Needle Pneumatic Hydraulic Shut Off Nozzle

Needle pneumatic/hydraulic shut off nozzle is mainly used to prevent leakage of high flow plastics such as nylons. Furthermore, it can also be applied in foam assisted injection and shorten cycle time. The actuator can be pneumatic or hydraulic depending on machine installation.

Application

  • Prevent leakage and shorten cycle time
  • Foam assisted injection
  • Combination with filter or color mixing
