Improvements introduced in the dispensers of pigmentation, applied to machines or extruders Injection Molding

摘要

The equipment consists of a hopper for the pigment concentrate, which drops onto an endless screw driven by a DC motor with control box which receives a signal from the shaft of the main machine. The speed of the screw is synchronised with the endless screw of the extruder by a receiver of electromagnetic impulses which sends a signal related to the speed of the extruder screw.
