Ewikon Hotrunner Systems of America Inc. introduced an electrical needle drive for valve-gate systems.
The drive unit is designed for use with HPS III-NVE 1 and HPS III-NVE 2 valve-gate systems, with needle drive positioning in the clamping plate. It is suitable for nozzles with flow channel diameters of 3-9 millimeters, in four installation sizes that cover a broad range of shot weights.
Electric needle drive is good for clean room molding of medical parts. Ewikon said the needle drive also is well-suited for valve gates running on all-electric injection molding machines.
The controller can precisely operate up to eight needles. Each needle can be separately selected, adjusted, or switched off by changing to a manual setup mode.
During setup, you can move the needle, stepwise, in increments of 0.05mm.
During operation, if a deviation is detected, the needle automatically readjusts itself within one molding cycle.
Ewkon Hotrunner Systems is based in East Dundee, Ill.
