- Optimized for highly viscous materials without the risk of vulcanization
- Designed for larger flow rates
- Flow-optimized geometry protects the material during injection
- Reliable opening and closing through active retraction
HPRE Retraction
actuated
for Elastomers
World class in
injection moulding
The HPRE needle shut-off nozzle was specifically developed for processing solid elastomers and HTV. An integrated cooling system reliably prevents premature vulcanization within the flow channel. The needle mechanism is actuated either pneumatically or hydraulically with active needle retraction, ensuring precise material separation at the mold interface while minimizing shear.
