Abstract

A process for molding an article having preselected portions formed of different organic plastic materials is described which comprises (a) positioning at least a first skin material essentially free of reinforcing fillers and at least a first core material containing reinforcing fillers in an elongated heating zone at preselected locations of the materials relative one to the other; (b) heating the materials to a temperature sufficient to melt each of the materials while maintaining said materials at their preselected relative positions; (c) exerting a force against an end of the melted materials; (d) linearly moving the melted material in response to the force through the heating zone and into a mold cavity; and (e) cooling at least the first skin and first core materials in the mold cavity. The process can be employed advantageously to provide substantially distortion free injection molded products having glass fiber filled large thin walled sections.
