ABSTRACT:
Method and apparatus for the high-speed stabilization of molded parts. Stabilization is achieved for parts ejected from a molding machine by bringing about a rapid change in the surface temperature of the parts during the course of their conveyance from the molding site. The result is skin-effect hardening which gives dimensional stability to the parts, allowing them to be conveyed away rapidly for further processing. This permits early ejection of parts from the molding machine and enhances production capacity.
