SHP
needle shut-off
spring-operated
World class in
injection moulding
The spring-actuated needle shut-off nozzle SHP was specially developed for users who require uncomplicated shut-off at high temperatures and pressures. This is achieved by positioning the spring system outside the melt flow. An axially movable needle in the nozzle is pushed against the outlet bore by spring force and closes it. At a melt pressure above 200 bar, the nozzle opens, while it closes again at pressures below 45 bar. The compact design facilitates installation and can be supplemented by a screen filter with minimal pressure drop. The SHP nozzle offers an efficient solution for applications with high temperatures and pressures and allows easy part replacement for versatile use.
