气动或液压驱动的机螺栓关闭喷嘴类型BHP用于处理热塑料。
对此喷嘴的支持是:
Cycle time reduction, shut-off in the nozzle of the melt-stream while withdrawing or dosing. With the BHP nozzle Herzog has designed a system which allows a single throughgoing melt flow channel. Therefore a much bigger flow channel is possible and that is responsible for a reduced pressure drop. With this single channel principle the so called “Memory effect” can be avoided. With the single channel system a cleaning of the unit is done within very short time (similar to an open nozzle).

包装,汽车和休闲行业,药用和电子设备。
手术:
组装集成的执行器(气动或液压激活)通过杠杆机制控制径向定位的螺栓。因此,熔体流的过程依赖于分离。螺栓机制以这样的方式构建,以使喷嘴的自动开口被过压。与针切系统相反,分离发生了。因此,在喷嘴孔口和关闭单元之间存在更长的孔。对于某些应用,这可能不合适。
