Thermoplastic molding process and apparatus

摘要

A thermoplastic molding process uses the thermoplastic molding apparatus to mold a part of variable thickness from a slab of material heated during extrusion. The thermoplastic molding system includes a thermoplastic extrusion die for the extrusion of a thermoplastic slab. The extrusion die has adjustable die gate members for varying the thickness of the extruded material in different parts of the extruded slab. A plurality of molds are mounted to the platform to feed one mold into a loading position while a second mold is in a release position.
