- Designed for larger flow rates
- Optimized for highly viscous materials without the risk of vulcanization
- Reliable opening and closing through active retraction
- Flow-optimized geometry protects the material during injection
BHPRE
Bolt shut-off
with retraction
for Elastomers

World class in
injection moulding
The BHPRE bolt shut-off nozzle was specifically developed for processing solid elastomers and HTV. An integrated cooling system reliably prevents premature vulcanization in the melt channel. The single-channel flow geometry avoids memory effects, and quick cleaning or color changes are easily possible. The actuation of the bolt shut-off can be done either pneumatically or hydraulically, including active retraction.
