Product Portfolio
  • Material Combination

  • Our products made from the combination of elastomers with plastics or rubber with metal can be found both in our individual components, the products for conveyor technology and in the field of belts and tapes.
      • Separate Components

      • Individual components from the field of material combinations are technical parts made of several materials, which only attain their full functionality when installed. Despite their comparatively simple construction, individual components are sometimes subject to enormous stresses. For this reason, we combine several materials with different properties in order to meet the demanding requirements of the industry.
          • Rubber-Plastic Elements

          • In many areas of application with extensive loads, components made of a single material quickly reach their limits. For this reason, we offer elements made of several, directly connected components that combine the advantages of different materials. Chemical-physical direct composites between thermoplastics and elastomers as well as TPE (thermoplastic elastomers) are our core competence.

            Since the elastic component is injected directly onto the stable thermoplastic body without prior priming, the associated costs can be effectively saved. In this way, applications in accordance with common food and drinking water requirements (FDA, BfR, etc.) can be guaranteed and demanding specifications of the electrical industry can be fulfilled.

            In addition, additional functions are integrated into components through material combinations. Bendable or filigree parts made of rubber become dimensionally stable and can thus be mounted in a functionally reliable manner. This leads to a reduction in the scope of assembly as well as additional reworking and lowers quality assurance costs. A central advantage of rubber-plastic compounds is that, unlike metallic materials, they are not prone to corrosion. Moreover, the total weight is reduced enormously by substituting the metals accordingly.

            We offer various material combinations of plastics and elastomers in direct bonding. In addition, an application-related material selection enables function- and cost-optimised solutions.

            Pipe clamp made of rubber and plastic:Our modular tube connector system was developed for connecting glass tubes in photobioreactors. The requirements for the rubber-plastic pipe clamp are extensive, because on the one hand the component must resist the existing pressure of the plant and on the other hand it must guarantee a reliable tightness.

            The simple assembly and disassembly of the pipe clamp using a torque wrench also eliminates the need for heavy power tools. Furthermore, the tight screw connection of conventional metal clamps often leads to glass breakage, which can be significantly reduced by using the Jäger clamp.

            The use of the rubber-plastic pipe clamp in other industries or with pipes made of different materials (glass-plastic or metal-plastic connections) is possible without any problems. They are already used in solar water treatment plants or in the plastics industry for granulate conveying.

            Pressure roller for seed drills:Components for the agricultural sector are usually exposed to various environmental influences and strong physical stresses. They must be resistant and should remain serviceable for as long a period as possible. Should individual components fail, this can have serious economic consequences, as the periods during which sowing and harvesting can take place are limited.

            Above all, material combinations of rubber and plastic allow reliable and consistent use of the machines, as they provide the necessary robustness despite their low weight and without the risk of corrosion.

            Seed drills use pressure rollers to regulate the depth of seed placement and for soil compaction after the sowing process. Previously drawn furrows are closed to prevent the seed from lying open in the field. For this purpose the press rollers must work permanently with appropriate pressure and on different types of subsoils.

            The JÄGER Group manufactures assemblies made of high-strength rubber and highly resistant plastic for this purpose in order to withstand the extensive influences such as abrasion and specific force-displacement behaviour. The penetration of dirt into the pressure roller bearing is optimally prevented by a well thought-out construction of lip seals and dust caps.

          • Rubber-Metal Elements

          • The combination of the specific properties of rubber and the known metal properties results in a very wide range of applications for construction elements made of rubber-metal compounds. We encounter them in all branches of industry as clutch buffers, friction wheels, bearing elements, spring and damping elements, bushings, valve balls, piston bodies, stators, disc springs or also as shaft bearings. In particular, machine feet and other rubber buffers, which serve to damp oscillations and vibrations, are used in mechanical and apparatus engineering as well as in measuring instrument technology and precision mechanics. The JÄGER Group offers an extensive range of different materials and hardnesses in the field of rubber-metal elements both for standardized and for components designed according to customer specifications.

            Suspension elements:Suspension elements manufactured as moulded articles with a firmly adhering connection of rubber and metal are used as components for vibration insulation, shock absorption and noise damping. While the actual spring body is made of rubber, the metal is used for stabilization and fastening.

            Compared to insulators made of other materials, mounting elements made of rubber-metal offer the advantage of damping, damping and springing. They are maintenance-free as well as easy and quick to install. In addition to an extensive range of standardized bearing elements which are kept in stock, we are your competent partner for the development of special parts.

            We supply suspension elements in the following designs:

            • Silentium Drive, the quiet innovation in the combine harvester
            • rubber-metal buffer and elements
            • torsion bushings
            • conical bearing elements
            • machine feet as rubber-metal connection
            • hollow springs
            • rubber-metal rails
            • axial and radial bushings
            Predominantly natural rubber (NR) is used for this purpose.

            For special requirements, however, the use of alternative materials is possible and sensible.

            For applications in the upper temperature range, for example, silicone is a suitable material.

            Injection molded seal:In many technical systems, the highest demands are placed on the individual components installed with regard to reliable sealing. In addition, the assembly process of individual components is often difficult, as conventional flat gaskets or profile gaskets cannot be installed due to the lack of space. For this reason, we offer the possibility of vulcanising the seals directly onto metal lids or housings using a tool in the injection moulding process. Thus the gasket is directly connected to the metal component and offers the following advantages, especially compared to freely applied gaskets:

            • precise seal cross section
            • profiled sealing cross sections with lips possible
            • constant cross section over the entire seal length
            • no butt joint and therefore better sealing
            • Connections without adhesive application possible

            Coating for rollers:In roll coating, metal cores are coated with a rubber layer, thus enabling a combination of both material properties. During production, the unvulcanised rubber is either wound onto the metal core or applied in a compression or injection mould to vulcanise it afterwards. The range is supplemented by roll cover hoses, which are already vulcanized and then wound under pretension onto the metal core.

            We also offer covers made of already vulcanized rubber sheets, which are glued to the metal core with special adhesive. In many cases, roller covers are exposed to several stresses at the same time. This is why special experience is required to determine the cover quality, the design of the core and the surface quality. We have decades of experience in this field.

          • Balls

          • 主要用作橡胶球和塑料球closures in valves and pumps or for the cleaning of pipelines, heating systems and screening plants. For our balls we use different types of rubber and plastic depending on the requirements in order to be able to offer the right material properties for each application. For this reason, our valve balls and screen cleaning balls can be found in many areas of the chemical industry as well as in mechanical and plant engineering.


            Valve balls:In valves, rubber balls act as a common shut-off device and thus prevent the unwanted backflow of gases, liquids or granular materials and dust. In the cage of the ball valves is the freely movable rubber ball, which is lifted from the valve seat by the inflowing medium. In the event of backflow, the ball is pressed back into the hard valve seat by force and its own weight, thereby sealing it. The valve seat should be adapted to the material used for the valve ball. Another field of application is the area of float balls. Ball concepts with floating elastomers and core materials are used here. For the various specific operating conditions, we have appropriate materials made of elastomers and plastics available.

            Screen cleaning balls:Our rubber balls are used for cleaning industrial screening plants. The balls are added to the material to be screened and their bouncing behaviour causes permanently repeated collisions with other balls, the material to be screened as well as the screen itself. These recurring impulses keep the screen passages clear. In order to counteract the resulting abrasion pressure and to ensure the required bounce characteristics, we use materials that are characterised by low abrasion and good rebound elasticity. This ensures the best possible results during the cleaning process. Our expertise in the field of balls enables us to produce a wide range of standard dimensions as well as numerous intermediate sizes in various degrees of hardness to meet your specific sealing application.

          • Compression Packing

          • Stuffing box packings are regarded as reliable and durable elements of sealing technology. Since they provide reliable leakage protection with high chemical and temperature resistance, stuffing box packings are used in various technical systems. They are preferably found in mechanical engineering such as pump technology or valve technology, but also in the chemical or metalworking industry as well as in tool and mould making.

            Stuffing box packings are used to seal a rotating or axially moving shaft against the effects of liquid or vapour pressures, as well as against penetrating dirt or escaping lubricant.
            A stuffing box consists of the stuffing box packing (the actual seal) and a stuffing box gland (a flange-like sleeve), with which the stuffing box packing is pressed axially by means of screws or springs.

            弹性密封material, the axial compression also results in radial compression of the stuffing box packing on the shaft. Thus the sealing gap can be adjusted to a minimum adapted to the operating conditions. A small leakage cannot be completely excluded, but is often desired.
            Advantages of compression packing: Universally applicable High mechanical strength Minimum cold flow Dimensionally stable Low leakage values and reduction of possible cross-sectional diffusion Fulfils the TA air and blow-out guidelines Suitable for use in the pharmaceutical and food industry (FDA and EU 1935/2004) Can be stored for an unlimited time

            Advantages of compression packing:

            • Universally applicable
            • High mechanical strength
            • Minimum cold flow
            • Dimensionally stable
            • Low leakage values and reduction of possible cross-sectional diffusion
            • Fulfils the TA air and blow-out guidelines
            • Suitable for use in the pharmaceutical and food industry (FDA and EU 1935/2004)
            • Can be stored for an unlimited time

            A special material — expanded PTFE (ePTFE):Our strategic partner TEADIT® uses a thermal expansion process following the sintering of the stuffing box packings to minimize the creep behavior of PTFE typical for the material. This results in sealing elements such as tapes or cords with monoaxial alignment or flat gaskets as well as plates with multidirectional structures. A high chemical resistance as well as a very good compressibility characterize ePTFE and predestine this material for sealing plastic and steel joints as well as for enameled flange connections. Furthermore, they often replace plates with hollow glass bead fillers.

        • Materials Handling

        • The field of conveying technology covers all applications where solid, liquid or gaseous media have to be transported over a certain distance. In order to be able to guarantee an economic transport of these goods in the long term, innovative further developments of the known processes are required. In this context, the best possible adaptation of the conveying systems to the respective operating conditions and processes in industry, mechanical engineering and plant construction is essential.
            • DELTA Transport System

            • The modular transport hose system is flexible and easy to integrate into existing systems. It consists of a delivery hose, seals and reusable, metallic flange couplings that are adapted to the application. The special feature of the suction and pressure hose system: The fittings are mounted around the hose from the outside so that no unevenness occurs within the conveying system. In addition, the hose connections do not come into contact with the medium to be pumped, thus enabling hydraulic transport of solids even in corrosive liquids.

              A pneumatic or hydraulic transport of abrasive solids can be easily mapped. The exact adjustment of the suction and pressure hose to the material to be conveyed results in a significantly extended service life compared to conventional steel pipelines.

              In addition, a significantly lower noise level is to be expected. The design of the system allows easy and flexible installation within the industrial plant. Due to the comparatively short installation times, unnecessary downtimes and the associated costs can be effectively avoided.

              The areas of application for these industrial hoses are diverse and range from the construction industry, power plants or gravel pits to the chemical industry and feed production. The delivery hose system is available as yard goods or in individual lengths as well as in many different dimensions. The assembly of complete hose line systems is also possible.
            • Pump Stators

            • Stators for eccentric screw pumps
              In the field of materials handling, progressive cavity pumps are successfully used for tasks that exceed the technical possibilities of pumps of conventional design. They have decisively expanded the range of available conveying systems and are used for conveying highly viscous, abrasive and corrosive media. The components of the progressive cavity pumps are the fixed stator and the rotating component, the rotor. Rotation and the design of both components create chambers through which the respective media are transported from the suction to the discharge side of the pump.

              Stators consist of a steel jacket lined with rubber. The composition of the rubber compound in the stator depends on the requirements of the progressive cavity pumps and the medium to be pumped.

              In materials handling technology, not only the abrasion behaviour but also the given physical, chemical and thermal medium properties are important factors that affect the composition of the material in the stator. The rubber mixture is therefore composed in such a way that the material wear of the stator is kept as low as possible. This increases the service life of your stators and prevents costly failures.

            • Pump Rotors

            • Rotors for eccentric screw pumps
              偏心螺旋泵属于积极displacement pump family and are used where the technical tasks exceed the possibilities of pumps of conventional design. In the field of conveying technology, they are used for pumping abrasive, highly viscous and corrosive media. This has contributed to a significant expansion of the range of available conveying systems. Eccentric screw pumps consist of a rotating component, the rotor, and the stationary stator located around it. The rotor rotates eccentrically, as its axis of rotation does not correspond to the axis of symmetry of the stator. The construction of both components form chambers through which the respective medium is conveyed by rotation in the pump via the suction to the discharge side. Rotors consist mainly of steel and have a special spiral geometry as the rotating centre in the stator. Different materials are used in the JÄGER Group in the manufacturing process of rotors for eccentric screw pumps.

            • Hose Assemblies

            • Hoses made of rubber, plastic and metal connections offer universal application possibilities in all areas of industry. They are used for conveying and conveying liquid, granular and gaseous media or for suction and pressure transmission. In addition, protective hoses are used to shield cables or other sensitive lines from external influences. The requirements for hoses and hose lines of the JÄGER Group are correspondingly extensive. These should be flexible, elastic and abrasion-resistant, but must also be pressure and vacuum stable as well as mechanically, thermally and chemically resilient. The fields of application for hose lines extend to most different industrial areas. They are used in the construction and food industries and in the chemical industry, as well as in agriculture, pump technology and pipeline construction.

              Assembled hose lines:Hoses and fittings are assembled by us into a functional and application-specific complete line. We procure all the necessary connecting and fitting parts, cut the hoses to the exact length and assemble them into ready-to-use systems. According to customer specifications, we can check and document the operating pressure for each hose line individually.

              我们的软管和配件从simpl延伸e water hoses to chemical hoses against aggressive media. Among other things we supply hose lines in the following designs:

              • Sandblasting hoses
              • Food hoses
              • Hoses against abrasive media
              • Metal braided ultra high pressure hoses
              • Heated hoses for two-component adhesives
              • Sterile tubes for the pharmaceutical industry
              • Heat protection hoses for electrical and hydraulic lines
              • Hose lines for the rotor blade production of wind power plants
              • Hose lines with leakage and drip-free couplings
            • SPIRA® Power Sections

            • SPIRA® stators for drill motors
              In addition to conventional stators, Artemis also produces stators with uniform rubber wall thickness under the brand name Spira®. These stators used in drilling motors are mainly used in the oil sector, but also for geothermal or mine drilling.

              Spira® stators offer many advantages over conventional stators. In particular, the higher torque for the same stator length, the uniform swelling in aggressive drilling fluid media and the uniform thermal expansion ensure significantly higher efficiency and longer durability. Spira® stators therefore drill to the required depth even in difficult applications without having to be replaced in between, thus saving a lot of time and money. The availability of different elastomers such as NBR, NBR-HR, HNBR and FKM for our stators offers optimal adaptation possibilities for your applications.

              Advantages of SPIRA® Stators

              • Higher efficiency due to increased motor differential pressure
              • Better heat dissipation
              • High performance, high temperature resistant NBR and HNBR rubber compounds
              • Increased durability / less stumbling / deep drilling
              • Suitable for motors with low speed and high torque
              • Higher torque at the same length compared to conventional stators
              • Shorter power sections at the same torque compared to conventional power sections
              • Reduced swelling and stator profile deformation due to aggressive drilling fluids
              • Uniform swelling around the stator contour
              • Uniform thermal expansion around the stator contour
              • Minimal stator profile distortion due to thermal expansion

              • Minimum internal heating, no hysteresis
              • High-precision, consistently high-quality stators and rotors “Made in Germany
          • Conveying and Sorting Systems

          • Within the JÄGER Group we produce belts and tapes for agricultural technology and mechanical and plant engineering. Through many years of practical experience, we know the requirements and problems of our clients and quickly find the application-specific solution for agriculture, industry, transport and services. Economic considerations, safety requirements, legal regulations and the desire for optimum performance utilisation are taken into account in our product development.
              • Sprockets and Drive Wheels

              • Drive elements are used in agricultural machinery as positive drive systems. Driving wheels or sprockets transmit the power of the motor to the screening belt. The JÄGER Group offers various drive wheels, which are available in diameters from 120 to 800 mm.

                Production
                Cast iron forms the heart of all drive wheels. Most drive wheels are separable to facilitate assembly and replacement. The wheel halves form matching pairs and must not be mixed. Our drive wheels are supplied drilled and keyed according to your specifications and, depending on requirements, the type and size of the keyways are cut according to German DIN (metric) or customs standards. The friction drive types FR, FRD and KW can be used with any belt type and pitch.

              • Flights

              • Consumers have high expectations of fruit and vegetables, they want to buy perfect goods. Potatoes whose skin is damaged or apples with bruises? They rarely make it into the shopping cart. For many buyers, appearance is synonymous with quality and taste. The harvest must therefore get from the field to the shops without damage.

                Previously used steel carriers are too hard and can cause pressure marks and scrapes on the crop. In order to avoid this, we have developed sieve bar belts with rubberized drivers for the agricultural industry, which enable the gentle transport of the crops. The drivers are used in potato harvesters, for example.

                The JÄGER GROUP offers individually adapted elastomer compounds for drivers and conveyor belts, which protect the crop. Furthermore, the light material also reduces the weight of the harvesting machines — the machines need less fuel and are therefore more environmentally friendly.

                Our flights can be divided into five categories:

                • RFL-Flight
                • MRF-Flight
                • Steel-Flight
                • Plastic-Flight
                • Snapping Flight
              • Process Belting

              • Profiled rubber fabric belts for loss-free product transport
                Our rubber fabric belts are characterized by precision, durability and efficiency. Efficient transport of a wide variety of goods requires constant new, innovative developments and improvements to the familiar systems. In this context, we focus on the best possible adaptation to the respective operating conditions and processes in industry, mechanical engineering and plant construction. We take belt speeds into account as well as the transport of sensitive goods.

                Special driver or cam profiles ensure loss-free transport of goods and can be manufactured by us from vulcanisation or plastic injection moulding tools with narrow tolerances.

                With individual surface structures and hole patterns, we open up further, diverse process possibilities. We optimize your production processes for the following applications, among others:

                • Washing plants for vegetables and fruit
                • Screening belts in the harvesting technology for sugar beets and potatoes
                • mechanical engineering for conveyor systems, for example for cement bags

                We offer among others the following materials in the field of belts:

                • Food safe mixture (for direct contact with food)
                • Especially ozone resistant mixture
                • NR/SBR/EPDM
              • Silentium Drive

              • Silentium Drive — the quiet conveyor system for combine harvesters
                "Silentium Drive", the new innovative conveyor system for combine harvester feeder channels with rubber fabric belts and cam drive eliminates one of the main sources of noise in the combine harvester.

                到目前为止,钢高速滚子链有蜜蜂n used in the harvester in the feed channel behind the cutterbar, which brings the crop to high speed with steel bars bolted on transversely and feeds it to the threshing units. This causes the chain and conveyor shaft to collide with each other. This creates the typical combine harvester noise, which is a considerable burden on the machine operator and the environment.

                "Silentium Drive"; for more power and comfort during harvesting
                Our “Silentium Drive” is based on a rubber fabric belt with parabolic cams, which replaces the conventional steel roller chain. This cam belt is manufactured in two versions: endless wound or with open ends and a special joining method. Bolts are vulcanized into the belt for an optimal connection between steel strips and belt.
                另外一项挑战是维护要求高ement of the steel roller chain used up to now. If not re-tensioned regularly, failures can occur and the combine harvester stops. Wear and tear is also problematic, as both the chain and the sprockets must be constantly monitored. If the combine fails during harvesting, the availability of parts and the replacement time are crucial. Every hour that the harvesting machines stand idle causes further costs.

                The advantages of Silentium Drive
                The “Silentium Drive” also helps to noticeably reduce maintenance costs:

                • The service life of the “Silentium Drive” is significantly longer than that of steel roller chains.
                • intake speed and conveying capacity are increased.
                • Chain wear reduced to a minimum.
                • Drive and deflection wheels are practically wear-free.
                • The permanent belt pre-tensioning by rubber fabric makes chain retensioning unnecessary.
                • Highest reliability avoids failures and downtime in the field.
                • low noise emission to protect the driver and the environment.
                • The costs per hectare are reduced.

                Over several years the “Silentium Drive” has been professionally developed and extensively tested by Broekema. The hunter company Broekema is a specialist in the development and production of rubber conveyor belts and screen chains with decades of experience in the agricultural machinery industry.
              • Belt Support Rollers

              • We offer you a wide range of idlers, idlers and support rollers for conveyor belts in harvesters. With them you can transport your crop safely and smoothly. Our product range includes lightweight rollers as well as plastic, cast iron and rubber rollers with one or two ball bearings.

                We are particularly proud of our specially developed idlers made of glass fiber reinforced plastic in combination with a rubber compound tread. The plastic has a noticeable effect in the lower weight, the elastomer ensures excellent running smoothness and provides the required elasticity for the idler.
                We manufacture the lightweight rollers from these special impact-resistant and wear-free plastics:

                • Polyurethane
                • Polyamide
                • Nylon
                These rollers are mounted either directly with a trunnion or with a hollow shaft.

                The plastic rollersare rubberized, have a low weight and are equipped with two ball bearings type 6005 2RS. They are available as standard with trunnion or open axle.

                铸铁辊和涂胶辊是equipped with two ball bearings type 6005 2RS as standard. Depending on the load, some rollers are offered with bearings of type 6206 2RS.

                All plastic, cast iron and rubberized rollers have a three-part seal on both sides as standard to prevent contamination:

                • Ball bearing seal
                • Oil-soaked felt ring (optionally with Vulkolan or steel filling rings)
                • Sealing lip and protective cap
              • Recycling Belting

              • Conveyor belts for recycling and disposal systems
                Especially in the waste management industry, forward-looking conveying solutions are increasingly required. We are your development partner with innovative ideas for your screening and conveyor belt — for the transport of the most diverse conveying media in a wide range of applications.

                The advantages of our conveyor belts at a glance:
                • High speeds possible
                • Smooth belt run
                • Energy efficient compared to steel chains

                For example, we equip beach cleaning machines with our conveyor belts. For many years now, these have been used daily in coastal areas to ensure clean beaches. For this purpose the soiled sand is picked up by a sieve belt, the sand is sieved off and falls back to the beach. Waste such as bottles and other larger particles are discharged separately.

                With our belts and the different pitches of the bar spacing we offer you the best possible influence on the quality of the screened surfaces. Heavy and sharp-edged stones, metals and organic materials can be picked up without any problems.

              • Fastening Components

              • Fastening components for belts
                The JÄGER Group supplies optimally coordinated fastening components depending on the installation situation and conditions of use. When connecting belts and rods, we distinguish between detachable and non-detachable connections. Detachable connections for quick installation on site are just as possible as riveted and endlessly vulcanized connections.

                High-quality products for demanding applications
                With our stepped or shafted and then vulcanised endless joints, we achieve release strengths far above the specifications and thus enable high load change stress. Artemis sets standards in the development of endless wound belts in any length as if “from a single mould”.

                Our innovative technology opens up further diverse applications for rubber fabric belts in a wide range of applications. These long-life belts replace heavy, noisy and wear-prone steel chains in machines for agriculture, waste management, soil remediation and beach cleaning. They make it easy to increase conveying speeds. The existing nominal strength of the belts can be fully utilised. In addition, compared to conventional splicing technology, a lighter fabric construction with lower strength can be made possible when used with smaller deflection diameters. A high pitch accuracy is achieved by a defined fabric pre-stretch. Even with friction drive with hydraulic pre-stretching, a long service life can be achieved with this system.

                Within the JÄGER Group, it is possible to continuously develop the different types of connections through laboratory and test bench tests under simulation of real operating conditions.

                • Waste Water Aeration

                • Jäger Umwelt-Technik has been developing and producing wastewater aerators for municipal and industrial wastewater treatment plants since the beginning of the 1980s, because an important element in biological wastewater treatment plants is the aeration system. With our aeration technology for waste water treatment we provide clean water worldwide. Our aerators are characterized by efficiency, reliability and durability. The JetFlex® tube aerator, for example, has been in continuous operation for almost 40 years. Saving energy is also important to us in order to protect the environment and reduce costs for plant operators.

                  Our JetFlex® product portfolio includes disc diffuser, tube diffuser and strip diffuser, which are suitable for various applications.

                  We develop the materials of our aerator membranes ourselves: In our in-house laboratory, our chemists test wastewater-resistant materials made of elastomers and polyurethane.

                  We use the following membrane materials for the aerators:

                  • Ethylene-propylene-diene rubber (EPDM) for waste water in municipal sewage treatment plants
                  • Nitrile rubber (NBR) and polyurethane (PUR) for use with oily waste water in industry
                  • Silicone rubber (SI) for special industrial plants
                  • Fluoroelastomers (FKM) for special treatment processes

                  The disc diffuser and tube diffuser are available with membranes made of EPDM, silicone, PUR, NBR and FKM, optionally with PTFE coatings. Both types of diffuser convince by low maintenance and quick installation. The product range is completed by our strip diffuser made of PVC with a micro-perforated membrane made of PUR. They are characterized by easy installation on the pool floor and a long service life.

                    • JetFlex® CBD

                    • JetFlex® CBD for more efficient mixing with air
                      For special applications our product portfolio also includes coarse-bubble aerators. These are available either in plate design or as stainless steel tube aerators. Used in the grit chamber of a sewage treatment plant, in sludge stabilization basins or as post-aeration, they offer the possibility of passing large air volumes and thus circulating the medium in the best possible way or ensuring a certain oxygen concentration in the effluent. In addition, the aerators can be used in aeration tanks to induce vertical flows and thus prevent sludge deposits on the tank bottom. This type of aerator, when operated continuously, can be regarded as completely maintenance-free.

                  • Marine Technology

                  • As the newest member of the JÄGER Group, Jaeger Mare Solutions GmbH works on the topics of scour, corrosion and noise protection for offshore wind energy, the maritime industry and marine technology.

                    We provide resource-saving and environmentally friendly solutions for the maritime sector. These include both our hose systems such as the bubble curtain for reducing underwater noise during offshore construction work and our innovative products made of sustainable materials such as basalt for offshore structures. In addition to the finished component, we also offer you a complete service — from the initial idea to tests in the water and product use on the high seas.
                      • Scour Protection

                      • Scour protection: basalt bags
                        我们为您提供个人保护被清洗ed out or undermined in the sea and also in inland waters — with our Jäger Mare Solutions basalt bags. The application possibilities of basalt bags are endless — we think ahead together with you. Developed for offshore applications, the potential behind the idea is becoming increasingly apparent.

                        Offshore wind turbines in particular are faced with the challenge that the ocean currents erode the soil layer around the foundation. This process is usually counteracted with the backfilling of stones.

                        However, the challenge cannot always be solved in this way. Sometimes the right rock is not available in the region in question to stop the scouring process.

                        Jäger Mare Solutions basalt bags are a flexible and environmentally friendly solution. The bags are made of a specially developed basalt fabric and are conveniently filled with round gravel or sand on site. Besides the application as scour protection, our Jäger basalt bags can also be used for the weighting of submarine cables or pipelines and as fixation in dike and coastal construction.

                        Your advantages of our Jäger basalt bags:

                        • High inertia of the filled bags
                        • Flexible filling of the bags on site
                        • Rock independent
                        • Easy installation Temperature resistant from ‑260°C to 800 °C
                        • 100 % UV-resistant No rotting of the natural tissue
                      • Corrosion Protection

                      • Basalt fiber protectors for offshore plants
                        Jaeger Mare Solutions manufactures durable protectors from a composite of basalt fabric, which protect steel structures in the offshore sector both against corrosion and mechanical stress. At the same time, the increased friction between the steel structure and the rubber fender caused by the protector promotes safe climbing over for technicians. Thanks to the long service life of our protectors you reduce your maintenance costs many times over.

                        Boatlandings of wind turbines are exposed to particularly high loads — maintenance boats damage the surface coating of the boat landing during docking due to the up and down movement caused by waves.

                        Hunters Mare Solutions protectors provide a remedy: The hard shells made of basalt fabric and vinyl ester resin are attached to the fender tubes with an adhesive specially manufactured for this application — similar to a shin guard. This can be done both on- and offshore.

                        Since basalt is a natural product, it is also non-toxic and therefore absolutely future-proof. Hunter’s protectors have to be as well, because even in cold salty sea water and under high UV exposure our protectors have a very long life span due to the basalt fabric.

                        Your advantages thanks to our JÄGER protectors:

                        • Cost-efficient by reducing maintenance costs
                        • Abrasion-resistant: long-term protection against mechanical damage
                        • UV-resistant
                        • Flexible installation both on- and offshore
                        • Individually definable length and color possible
                        • Safe passing of the technicians
                        • Corrosion protection
                        • Shock absorbing at mechanical loads
                      • Noise Mitigation

                      • Noise protection system: Bubble curtain
                        Jaeger Mare Solutions GmbH will provide you with a noise mitigation system tailored to your requirements. In addition to the proven conventional Big Bubble Curtain (BBC), we offer you two novel systems for reducing underwater noise.

                        Underwater jobs such as laying foundations or detonations of munition can cause substantial sound emissions. Particularly the construction of offshore wind turbines causes noise which can adversely affect sea dwellers. With its Big Bubble Curtain, Jaeger Mare Solutions contributes to the protection of marine animals during rammings of the heavy offshore foundations. For the benefit of the kind-protected porpoises, differently defined noise level limit values must be adhered to. The goal of Jaeger Mare Solutions is not merely the adherence to these values but a general minimization of sound emissions.

                        The Big Bubble Curtain
                        The Big Bubble Curtain is comprised of one or two hoses which are laid out in a ring around the source of noise. The perforated hoses are pressurised with compressed air – bubbles emerge from the sea-bed to the surface of the water which create a ring-shaped protective wall around the noisy construc-tion site. With the help of the bubble curtain the sound waves extensively spreading over the seabed are broken multiple times, decreasing the sound intensity and thus protecting the marine animals. After deployment, the hose system is retrieved and brought to the next construction site.

                        The Jaeger CBC
                        Our Conducted Bubble Curtain ensures less noise in the direct vicinity of the ramming point. Jaeger Mare Solutions is currently developing a flexible Conducted Bubble Curtain which is directly attached to the steel rod rammed into the seabed and which creates a dense net of air bubbles. This reduces the noise of the over 1000 required rams directly at the source while ramming the pile into the seabed.

                        The Jaeger BBC
                        With our new hose system, which is still under development, we can achieve the same noise mitiga-tion performance with substantially less pressure. For this reason, Jaeger Mare Solutions employs a technology developed for waste water treatment which has been tried and tested for 40 years at Jae-ger Umwelttechnik. With our innovative Big Bubble Curtain, we want to protect the marine animals, encourage the development of renewable energies, and reduce the costs for our customers. This is achieved with an improved bubble performance and the reduction of the required compressors.

                        • Cleartec® Biotextil and BioCurlz are used as fully submerged fixed beds in the biological stage of a wastewater treatment plant. The media are fixed in a stainless steel module that can be mounted above an existing aeration system or with integrated diffuser. The module dimensions are influenced by the required amount of Cleartec® Media and the aeration tank geometry. The modular design of Cleartec® provides an easy to install and low maintenance system.

                          The Cleartec® module consists of:

                          1. Stainless steel module
                          The stainless steel module serves as a supporting structure for Cleartec® Media (Biotextile and BioCurlz). The biotextile panels are fixed in the module by support tubes which are built into fixing loops. Each biotextile sheet has up to four loops, depending on the total material length. BioCurlz are fastened in the module by metal-reinforced support rods.
                          2. Cleartec® growth media
                          The textile structure of Cleartec® BioTextile and BioCurlz offers a large surface area and high roughness. It supports ideal conditions for the growth of biofilms. The textile flexibility associated with the air flow generated by diffuser regulates the biofilm thickness and prevents media clogging.
                          3. Diffuser
                          Fine bubble aeration diffuser are installed underneath Cleartec modules and the textiles. The diffuser have two functions to supply microorganisms with oxygen and to create a vertical flow. This vertical flow helps to control the biofilm thickness and contributes to its constant regeneration. It easily removes parts of the old biofilm and provides space for new active microorganisms to attach themselves to the media.

                          Advantages of the Cleartec® module for wastewater treatment

                          • Optimal growth conditions of the biomass
                          • Easy handling of the individual modules — even during operation
                          • Durability and time saving through maintenance-free operation
                        • IFAS-Process

                        • IFAS systems in waste water technology
                          An IFAS process (Integrated Fixed Film Activated Sludge) combines the advantages of conventional activated sludge with those of biofilm systems by combining the two technologies in a single reactor. In an IFAS system, synthetic media are used in the activated sludge tank as growth area for additional biomass. This combination allows a much higher biomass concentration and sludge age compared to conventional activated sludge processes.

                          The solid biomass also helps to improve the resistance of the system to organic or hydraulic shock loads. Our IFAS technology has been integrated into municipal and industrial wastewater treatment plants to modernize existing systems (improving treatment capacity and wastewater quality) and reduce the space requirements of new plants (by optimizing the aeration tank volume). With the IFAS process, an increase in treatment capacity of up to 100 percent can be achieved without construction work.

                          • Rubber Solutions

                              • The success of our company is based on the material rubber — benefit from our many years of know-how and our own mixing plant. Our chemists are very familiar with the material properties of rubber and the various manufacturing processes such as compression molding, transfer molding and injection molding.

                                We produce rubber products for sealing and damping worldwide. In the field of sealing technology we produce rubber profiles, O‑rings, molded rubber parts and foams. The latter two products are also suitable for insulation and damping. Our rubber hoses are also used in a wide variety of industries. The flexible hoses can be used to transport liquids or solids. Our products are not only used in industrial applications, but also in professional sports. For example, we also manufacture billiard boards for tournament tables from high-quality natural rubber.
                              • Power Transmission

                              • The field of drive technology includes all elements for the transmission of power and motion between different shafts. This transmission enables, for example, an effective speed conversion, the control of motion sequences in industrial production facilities or the general transport of goods. The JÄGER Group offers a wide range of products, especially for the area of belts and tapes made of rubber, plastic and various material combinations. In contrast to chain drives, which have a high degree of efficiency but do not allow any twisting within the system, belts and bands offer a significantly lower noise development with low maintenance. For these reasons, they are used in mechanical and plant engineering, the packaging industry as well as in the equipment and agricultural machinery industry, among others.

                                Non-positive drive elements
                                If the energy in a technical system is transmitted by the frictional forces generated between belts and driving wheels, this is referred to as non-positive drive elements. These are used wherever no synchronous movement of the elements is required and the drive may or should have slip. For this area we offer, among others, V‑belts, V‑ribbed belts and flat belts.

                                flat beltshave a rectangular cross section and, like all non-positive drive elements, transmit energy exclusively via frictional forces. The contact surfaces of the associated drive wheels usually have upwardly curved or raised edges to prevent the belts from slipping off the pulley.

                                V‑beltsare characterized by their easy installation and long service life and allow a high transmission ratio. They are available with sheathed or open-flank design and offer higher transmittable power than flat belts.

                                V‑ribbed beltshave individual ribs which run lengthwise to the belt itself. The larger contact surface on the V‑belt pulley results in greater friction and thus a higher power transmission than with ordinary V‑belts. They are very well suited for the simultaneous drive of auxiliary units.

                              • Billiard Cushions

                              • Artemis tournament billiard cushions made of rubber
                                In the billiard sport there are up to 35 different types of games, which take place on tables of different sizes. In pool billiards, the game is usually played on billiard tables measuring 2.54 meters by 1.27 meters. The increasingly popular game of snooker in this country is played on larger tables. In addition to the selection of billiard balls and cloth, the quality of the rubber cushions is crucial for the game.

                                Artemis billiard cushions are in demand from national billiard associations as well as from renowned table manufacturers. Our profiles can easily be glued to the billiard table and guarantee precision in the course of the game at tournaments and thus objectively comparable game results.

                                Our billiard cushions are — in contrast to many cheaper products — provided with two cotton fabric pads during production and heated in molds. This guarantees a synchronous run over the entire production length.

                                The materials used, BIBA RED, TBB GREY and KHF GREY, consist mainly of high-quality natural rubber. Additives according to our formula give the rubber mixture its special suitability for the game of billiards and excellent resistance to ageing.

                              • Freehand Products

                              • Freehand rubber articles are all parts that are handmade from intermediate products by grinding, sawing, turning, milling and drilling. Accordingly, no metal molds are used for this manufacturing process to represent the required dimensions and geometries. We envisage freehand rubber articles when the costly production of molds is not profitable or when a special molding is required for test parts or small quantities. Freehand articles are also produced in series as rubber elbows, hose rings and turned parts.

                                The processing of plates, blocks, tubes, hoses and solid rods is done by hand using mechanical aids. Sophisticated production techniques and qualified personnel guarantee high quality and constant dimensional accuracy. Due to their extensive design possibilities, freehand articles can be used in the most diverse areas. These include general mechanical and plant engineering, pump technology or agricultural technology.

                                Rubber bends
                                Bends made of rubber are used in systems where the directional flow of gases or liquids is to be diverted. When choosing the right material, rubber offers the advantage over metal manifolds that it can also be used to transport corrosive fluids. In addition, a certain degree of flexibility can be guaranteed with reliable dimensional stability.

                              • Rubber Molded Parts

                              • For the production of rubber molded parts, plastic rubber compounds are placed in specially designed metal molds. The desired geometry is first formed by pressing or injection, and then the mixture is stabilized by vulcanization. This process gives the material its specific elastic properties.

                                Rubber molded parts are particularly suitable for damping, sealing, insulating and protecting and thus offer almost unlimited application possibilities. They can be found as rubber buffers, seals and much more in all areas of mechanical and plant engineering, the electrical and vehicle construction industry, energy technology as well as agricultural and environmental technology. Most molded rubber parts are not standard or norm parts, but are developed for specific functions in close cooperation between our product development team and our customers and then manufactured to order.

                                Multifunctional
                                Molded rubber parts are elastic, pressure-resistant and abrasion-proof as well as mechanically and chemically resistant. The respective operating conditions and the desired function determine the choice of material and the type of manufacturing process. Each manufacturing process has specific characteristics and must therefore be precisely matched to the order to be produced and the associated purchase quantities. We can map both individual and series production as well as mass production within the JÄGER Group or via our strategic partners.
                                For the production of rubber molding parts we have, in addition to conventional vulcanization presses in which displacement and transfer molds are used for the compression molding process (CM) and the transfer molding process, injection presses for the injection molding process (IM) of the most modern design. Material, production process and production method are coordinated in such a way that an economic optimum in production and application is achieved. Among other things, the use of cold runner technology contributes to this, which also helps to protect the environment and conserve resources.

                                Customized
                                Molded rubber parts are subject to the influence of changing media, temperatures and climatic conditions, mechanical stresses or ozone and UV exposure from solar radiation, which limits their useful life and service life. In order to guarantee high quality, we rely on our own material development and production.
                                For this purpose, we carry out mechanical and dynamic tests, vulcanization and processing tests as well as material and damage analyses in the development laboratories of the JÄGER Group. For further analyses (e.g. electron microscopic examinations) we cooperate closely with the German Institute for Rubber Technology (DIK) in Hanover.

                              • 橡胶垫和橡胶板

                              • 乍一看,橡胶或橡胶垫出现to be comparatively simple semi-finished products, but they reveal enormous potential for all areas of industry. They are used for protection against abrasion, for the insulation of vibrations or also for electrical insulation. For occupational safety, rubber mats and rubber sheets are used as anti-slip underlays in almost every production area. The materials, thicknesses or surfaces used are directly adapted to the respective areas of application. These range from general mechanical and plant engineering to fittings and apparatus engineering to the chemical and electrical industries.

                                Cushioning mats
                                Cushioning mats and panels are usually made of rubber granulate or cellular materials. These are used to decouple machines and systems and are intended to minimize the vibrations generated during production. The damping of vibrations contributes to the protection of the machine environment as well as to a longer service life of the actual plant. It also reduces the maintenance requirements of susceptible components, which can significantly reduce the associated costs.

                                We supply rubber mats in the following designs:

                                • Rubber sealing plates
                                • High pressure sealing materials
                                • 橡胶垫(细胞的细胞材料制成的nd sponge rubber, polyurethane and silicone foams, foams)
                              • Rubber Profiles

                              • 橡胶生产资料由extrusio没完没了地n. For this purpose, the unvulcanized rubber mixture is plasticized in extruders and brought into the appropriate cross-sectional geometry by means of attached extrusion tools (mouthpieces) in the extrusion head of the system. The mouthpieces can be adapted as required to produce different profile cross-sections, so that the right geometry can be realized for every application. The profile is dimensionally stabilized by subsequent vulcanization. Vulcanization in a steam boiler or salt bath is used here, as well as hot air vulcanization, UHF production or IR shock vulcanization. Rubber profiles are used for protection or sealing in vehicle construction, the construction industry and general mechanical engineering, among others.

                                Individual
                                In the case of dynamically stressed profile seals, we calculate the necessary contact pressure forces and then adjust them specifically by means of hollow chambers or foam structures. The necessary overlap or the gasket stroke can be numerically optimized by means of FEM analysis. These special designs are supplemented by a wide range of standard profiles.

                                • full profiles made of one material
                                • duplex or n‑plex profiles made of several materials or hardnesses
                                • Foam rubber profiles and soft rubber profiles and their combinations
                                • Edge protection profiles with and without sealing and covering elements

                                Finishing techniques
                                To improve the handling and to facilitate further processing, we offer various finishing options.

                                • Simplified handling of small parts through kiss-cut punching to the liner
                                • Unique identification of the components through multicoloured liners and printing
                                • Partial notching and exact cutting to length to achieve tight bending radii of circumferential seals
                                • Injection of mould corners in elastomer or TPE
                                • Functional surfaces through flocking and bonded coatings
                                • connection of cut surfaces
                              • Rubber Hoses

                              • Rubber hoses are used in various industrial areas. In the first instance they serve as flexible means of transport for fluids or solids (as granulate or powder) and thus offer a decisive advantage over static pipes made of metal or plastic.

                                The properties of the material rubber open up a wide range of applications for hoses in the most diverse fields of application. Whether elastic and abrasion-resistant or mechanically, thermally or chemically resistant, the specifications of rubber hoses are virtually unlimited.

                                Where the material reaches its limits, it is also possible to extend the existing properties with textile inserts or metallic reinforcements. Technical hoses are usually standardized industrial products that are standardized according to DIN or ISO.

                                The JÄGER Group offers a comprehensive range of hoses for all areas of application and supplies hoses for pressure and vacuum stress in practical dimensions, wall thicknesses and lengths with and without fittings. This diversity enables reliable use in agriculture and the food industry (e.g. dairies) but also in gravel plants, mechanical engineering and pipeline construction.

                                Different hose variants
                                Since both the design and the materials and manufacturing processes used for a hose must always be precisely adapted to the existing conditions of the application, there is no hose that can meet all requirements and loads at the same time. For this reason, we advise you from the very beginning in order to precisely understand the challenges facing the component and to achieve the desired goal together.

                                Mandrel heated molded hoses
                                Narrow bending radii and limited installation space require the use of pre-bent shaped hoses produced in the mandrel heating process. Hoses manufactured on mandrel are extruded or wound. These usually have only very narrow dimensional deviations in the inner and outer diameter and are therefore suitable for applications which only allow very narrow tolerances. On customer request we develop hoses of any length and diameter. By means of injection molding, form-bound branches and fittings can be vulcanized on.

                                We supply rubber hoses in the following designs:

                                • Hoses without inlay — for simple applications
                                • Hoses with textile or metal reinforcements — dimensionally stable and pressure-resistant
                                • Hoses with spirals or rings and ribbed on the outside — for suction operation and additional flexibility
                                • Hoses with rings — compressible to a certain degree
                                • Hoses with braided or spiralled metal reinforcements — for very high pressure loads
                              • O‑Rings

                              • O‑rings are used in all systems as reliable elements of sealing technology. These are endless rings with a round cross section which are manufactured as molded parts from rubber (partly also from plastic). The possibility of axial or also radial sealing of different fluids (gases and liquids) distinguishes the simple and robust components.

                                Here, the JÄGER Group has a wide range of different materials and dimensions at its disposal so that the correct parameters are available for every application. With the correct groove design and material selection, a seal can be used for a long period of time, both stationary and moving, within the temperature limits of the material. The advantage of O‑rings is that they are easy to install and require little installation space.

                                O‑rings made of EPDM and NBR
                                As with all technical products, there is no universal solution for O‑rings for all applications. The material as well as the dimensions and assembly of the O‑rings must be adapted to the respective overall system and the given influences. If an assembly is exposed to external weather conditions, the material EPDM (ethylene propylene diene rubber) has become established.

                                Since EPDM is highly resistant to ozone and ageing and also has good resistance to cold temperatures, the material is predestined for such areas. However, EPDM has no resistance to mineral oil-based media and swells strongly under their influence. In this case, NBR (acrylonitrile-butadiene rubber) is the ideal choice, as this rubber is highly resistant to greases and oils based on mineral oil.

                                We supply O‑rings in the following designs:

                                • 肖氏硬度从40 - > 90±5海岸
                                • Black or colored
                                • 有或without coating, e.g. siliconizing, PTFE-coating, graphitizing, molycoating, talcumizing, painting
                                In addition, we offer a wide range of static seals, rotary seals, hydraulic seals, wipers, guide elements and retaining rings.
                              • Foams

                              • Foams are materials with a porous structure and the associated low density of rubber or plastic. The low specific weight and good compressibility open up a wide range of applications for foams.

                                Porous materials such as silicone foam, cellular rubber, sponge rubber as well as foam rubber offer a resistant supplement to solid materials and are excellent for insulating or sealing. For this reason, foams are widely used in vehicle construction, mechanical and plant engineering, medical technology, energy technology, the electrical industry, communications and agricultural technology.

                                Production
                                Foams are produced with or without pressure, depending on the process. Foaming is achieved by mechanical or physical processing or by a chemical reaction using blowing agents. The selected process and the raw material composition of the materials have a decisive influence on the achievable density of the foams, as they have an open, closed or mixed cell structure after production. The processing can be done by extrusion or injection molding. Prefabricated sheet products are often die-cut.

                                Common to all foams is the low weight, due to the low density. Parameters such as restoring force, compression set (DVR), water absorption capacity, acoustic decoupling, shock absorption, damping and insulation capacity sometimes differ greatly.

                                Compression behavior
                                通常,橡胶组件是不可压缩的firmly installed state if there is no room for them to escape when force is applied. An exception, however, is in the form of foamed elastomers. Due to the cellular structure of the material, the space required for displacement within the pore structure itself is provided, allowing compression even in fully filled spaces. This property predestines foams for sealing and insulation applications where no other material can offer an alternative.

                              • Punched Parts & Blanks

                              • 夯实部分和pl的空格用橡胶制成的(也astic or composite materials) are used in all industrial plants and machines. Among other things, they serve as seals, supports, wipers and dirt traps and are usually produced by machining semi-finished products. In particular, rubber flat seals, which are manufactured, for example, on punching machines, water jet cutting machines or plotters, offer extensive application possibilities. They are intended to compensate for gaps that occur on surfaces that come into contact with each other and provide a secure seal against media from inside and outside.

                                The starting materials are mainly sheets of various mostly elastic materials with and without inlays or mats with surface design. In addition to the standard designs with grooves or burls, we also offer customer-specific surface patterns. In addition to the solid materials, porous materials such as cellular rubber, sponge rubber, polyurethane and silicone foam can be used excellently for various sealing requirements. Stamped parts and blanks can be found in all areas of industry. They are produced for mechanical and apparatus engineering, the food industry, pipeline construction, the electrical engineering industry, vehicle construction or agricultural engineering, among others.

                                Processing of flat semi-finished products — water jet cutting
                                In contrast to the usual punching process, the manufacturing process of water jet cutting offers the advantage that it is particularly suitable for soft or multi-layer materials. In addition, materials of varying hardness and fine geometries can be processed. Plates lying flat on a metal grid are cut with a precisely directed thin water jet. The large number of different materials and the large differences in the number of stampings and blanks require specific production facilities. We therefore rely on strategic supply partners who complement our in-house production for projects with small quantities and specific manufacturing processes.

                                Refinement
                                Various finishing techniques can be used to significantly extend the possible uses of stamped parts and blanks. To facilitate component handling and reduce assembly work, the following techniques, among others, can be used

                                    • Flip ‘N Seal Slide-Out Sealing System®
                                      Today’s recreational vehicles offer a significant amount of features and amenities as many consumers seek the outdoor camping experience but want the same comfort as at home. One way in which a recreational vehicle can create more interior space is the “slide-out system”.

                                      While the “Slide-Out System” delivers an outstanding solution to maximize interior RV space, protecting the interior space from the outside elements creates a significant design engineering challenge. The sealing system plays a significant role in creating a watertight interior, minimizing temperature intrusions while delivering durability under dynamic and static loading conditions over a wide range of temperatures.

                                      通过与rapidl房车制造商密切合作y expanding the use of Jaeger Unitek Sealing Solutions Patented Flip ‘N Seal Slide-Out Sealing System®, together, we have met the complex application demands with Slide-Out sealing requirements. The results are a watertight seal, a one-part sealing solution vs. a two-piece design, lower installation costs during seal preparation and installation, and the elimination of reduced warranty claims. For consumers, this translates into the growing use of RV slide-outs to create more interior space, protection from the outdoor elements, satisfaction and enjoyment in the great outdoors.

                                      The advantages of Flip ‘N Seal include:

                                      • Excellent adhesion to surfaces of recreational vehicles for a secure seal against mechanical fastening methods resistance to repeated extraction at temperatures from ‑40°C to +90°C UV and weathering resistance for waterproof sealing performance The use of a viscoelastic foam copes with demanding loads and at the same time offers the elasticity to functionally seal if the individual components have different coefficients of thermal expansion during temperature changes Design freedom to take into account the significant variations in pull-out geometries and dimensions of leisure vehicles damping characteristics which cause an interruption of the vibrational forces while driving and thus minimize the energy transfer to other parts of the recreational vehicle Heat activated bond between the inner foam and the polymeric surface of Flip ‘N Seal forming a high strength sealing barrier
                                    • Plastic Molded Parts

                                    • Plastic molded parts insulate, decorate, connect and stiffen. Thanks to their specific properties, they are increasingly replacing components made of metallic materials. Their advantages include high design freedom, low specific weight, good corrosion resistance and high chemical resistance.

                                      The incorporation of additional components into the plastic matrix enables a targeted modification of the material properties. By incorporating elastomer particles, rubber-like properties can be created. The addition of selected fillers, on the other hand, offers, for example, an improvement in the electrical conductivity of the plastic molded parts or a targeted improvement in the mechanical properties.

                                      Plastic molded parts can be found in all areas of industry. Among others, they are produced for mechanical and plant engineering, the food industry, medical technology, the electrical engineering industry, vehicle construction, the energy sector or agricultural technology.

                                      Production Engineering
                                      The decisive factor for a plastic molded part that is convincing in use and withstands the given influences is the correctly selected production process. Within the JÄGER Group as well as through our strategic partners, various projects can be realized with different processes.
                                      Among other things we offer:

                                      • injection moulding
                                      • blow moulding
                                      • foam
                                      • thermoforming

                                      Simultaneous development
                                      The parallel development of plastic molded parts and tooling concepts ensures optimum throughput times and the best possible product performance. The use of simulation software for FEM (Finite Element Method) strength calculations and for displaying the mold-filling behavior (mold-flow) ensures the structural stability of the components and ensures reliable process sequences later in production.

                                    • Semi-Finished Plastic Products

                                    • Semi-finished or semi-finished products are made of various plastics and designate products with the simplest of geometries. Usually a single material is used, which is formed into the desired shape by forming or machining.

                                      Among other things, this mechanical processing is used to produce rods, profiles or sheets from selected plastics. Since the quality of the semi-finished plastic product has a decisive influence on the properties of the later end product, a correct choice of material must be made in advance. Among other things, resistance to certain media and the existing temperature conditions in use should be taken into account.

                                      Your projects are realized in close cooperation with the respective production departments, so that your requirements are implemented constructively. We will advise you individually and according to your application-specific requirements.

                                      Special material requirements:

                                      • food compatibility
                                      • biocompatibility
                                      • chemical resistance
                                      • resistance to radiation

                                    • Plastic Profiles

                                    • The material properties of plastic profiles allow a very wide range of applications. The raw material is processed as granulate into endless profile strands in the extrusion process by first plasticizing and melting it, then giving it the desired geometry and finally cooling it. This gives plastic profiles their dimensional stability and specific properties.

                                      与金属合金,这些属性可以增刊lemented and extended by certain additives. Thermoplastics such as PE or PP, for example, can be significantly mechanically reinforced by adding fillers. Compared to metallic materials, plastics offer the advantage that they are easy to shape, have a low specific weight, can be coloured as desired and are highly resistant to chemicals.

                                      Plastic profiles have a lower strength than metal profiles and a significantly lower heat resistance. For this reason, a precise knowledge of the operating conditions and the desired functions is required in order to be able to select the appropriate material for each profile.

We would be pleased to advise you on the selection of the material and on the functional and plastic design of the profile for your application.

                                      Co-extrusion for special applications
                                      Within the scope of co-extrusion, several different plastics with different properties can be brought together. For this purpose, several extruders are arranged in blocks of two or three so that the melt flows of the respective extruders run parallel and are joined to form a single profile strand. The resulting n‑plex profiles can cover a wide range of requirements. In addition, different colors or hardnesses can be combined.

                                      Fabrication and finishing
                                      The further processing of plastic profiles to finished parts according to drawings is usually carried out by downstream equipment within the production line. After cooling, profiles are drilled, punched or milled in the line. Fasteners, end pieces and caps can also be directly injection moulded onto cut profile pieces after the actual production process. Fastening elements such as clips can be formed by mechanical processing.

                                    • Plastic Hoses

                                    • Plastic hoses are used as flexible connections in various industrial machines. They are primarily used to transport fluids, granulates and powders, but also to protect the conveyed medium from environmental influences. In contrast to rubber hoses, plastic hoses can be manufactured in any color or even transparent. This guarantees a clear view of the conveyed medium. In addition to the material-specific properties of plastic, (textile) inserts as well as plastic spirals or metal spirals can be incorporated into the hoses. Plastic hoses are used, for example, in mechanical engineering, the construction industry or in wind energy, but are also found in the chemical industry and in agricultural engineering.

                                      Heat shrinkable tubing
                                      Shrink sleeves are used to sheathe sensitive components and thus protect them from environmental influences or various media. They are expanded during the production process directly during extrusion and only cooled down afterwards. As soon as the shrink hose is exposed to heat, it contracts back to its original size and thus reliably encloses the sheathed components. The so-called shrinkage rate (2:1; 3:1; etc.) indicates the ratio of the inner diameter before and after shrinking. Especially PVC tubing or also PTFE tubing is used in the electrical industry to protect cables or other conductors.

                                      The choice of materials
                                      Plastic hoses are made of different types of plastic and accordingly have different properties. Above all, the chemical resistance of the materials as well as their temperature resistance and physical properties are the main focus. However, plastics also differ considerably from an economic point of view, which is why the required conditions should be tailored exactly to the respective application. We advise you from the ground up and find the right hose for every application.

                                      We supply plastic hoses in the following versions:

                                      • shrink tubing hoses for line protection cable protection conduits suction hoses food hoses suction and pressure hoses
                                    • Protective Plugs & Protective Caps

                                    • Plastic protective plugs and caps are used to seal and secure sensitive and critical connecting parts and end pieces. Metal components are usually galvanized or painted to protect against corrosion. By attaching protective caps, these components are protected from scratches or other damage.

                                      Protective plugs are used to cover openings and bores or as dust protection for sensitive components. Both products can be manufactured in various plastics as well as in different colors. Due to their simple but at the same time indispensable function, they are used in the entire machine and plant construction as well as in the hydraulic industry.

                                      Different variants
                                      Due to countless possible applications, protective caps and plugs must have the most diverse geometries. A version without thread is suitable for protecting protruding components (screw heads or nuts), as these can be fitted comparatively easily and removed again if necessary. Plugs without threads can be used for permanent use in drill holes or other openings, but are difficult to remove again. Screw plugs or sealing screws are suitable here. These are screwed or unscrewed directly into or out of the intended opening and thus allow easy removal. A further possibility is provided by so-called strap plugs, which are fastened for quick assembly by simply pressing on them, but can be removed just as easily through the existing strap.

                                      We supply protective plugs and protective caps in the following designs:

                                      • valve protection caps
                                      • thread protection caps and sealing screws
                                      • protective caps for screws and nuts
                                      • tab stopper
                                      • screw caps including seals
                                      • dipping caps
