OFS-needle shut-off nozzle type NV
By the controlled closing and opening the flow canal, the cycle time can be reduced and a more exactly injection process is possible.
The OFS-needle shut-off nozzle is actuated pneumatically or hydraulically by a flanged cylinder. This nozzle can also be controlled by a linkage of the machine.
Because the controlled closing of the flow path, shorter cycle times are possible and there are less material loss. The OFS-needle shut-off nozzle is suitable for all thermoplastic materials. The size of the nozzle depends on the injection rate, the material and the screw diameter.
