Needle Actuation

Needle Actuation

The needles can be moved with single valve gate nozzles and in multiple nozzle and manifold systems with

single needle valve
lifting plate
sliding plate mechanism

and can be designed for pneumatic or hydraulic operation.
Special holes in the mould clamping plate allow the depth of the shut-off needles to be adjusted individually from the outside. The choice of needle actuation depends on the application, the available space and the size of the mould.
