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.
