HP powered pin shut off nozzles
Available from Herzog Injection Technology, Inc.
The Herzog® HP type nozzle is the best performing pin shut-off nozzle on the market today.
The assembly integrated actuator (pneumatically or hydraulically activated) controls a nozzle-axis positioned needle via a lever mechanism. The melt flow is therefore process dependently separated at the nozzle orifice. The needle mechanism is constructed in such a way, that with over-pressure an automatic opening of the nozzle is ensured.
Modules for filters, mixers and GAIM-applications complete the range of shut-off nozzle products.
