Machine nozzle with shut-off, type A(S) Technical description The spring actuated machine needle shut-off nozzles type A(S) are used in processing of thermoplastics, principally with low viscosity materials such as: PA, PPS, PE, POM, PP. Needle Needle Sleeve Finds application in: Packaging, automobile and leisure industries, medicinal and electronic equipment. Operation: The nozzle is opened directly from the injection pressure and closed again with spring power. A needle which moves axially in the needle shut-off nozzle is held in the closed position by the force of the spring. The nozzle...

Machine nozzle with shut-off, type A(S) Option: Integrated melt filter in A-Type nozzle General For a problemfree production process (keeping the injection opening clear) a final filtration of the material may be needed. The Herzog® melt filter is based on the so called „ gap filter principle“and can be assembled into the existing spring operated shut-off nozzle without any modification. Filter gap: A0 → 0.3 mm A1 → 0.5 mm A2 → 0.8 mm Retrofitting Just by changing the standard spring chamber with a filter-spring chamber the retrofit is already done and the nozzle is again operational....
