OFS-bolt shut-off nozzle type BV
By the controlled closing and opening the flow canal, the cycle time can be reduced and a more exactly injection process is possible. One flow canal technology.
application fields:
The OFS-bolt shut-off nozzle type BV is used for processing of thermoplastic materials and thermoplastic elastomers. An integrated pneumatic or hydraulic cylinder controls the bolt by a fixed lever, whereby the flow channel is closed and opened. The system is designed in such a way that there is no forced opening when the system pressure is present.
Due the one flow canal technology, the effect of stratification and memory effect during injection is prevented.
