An injection molding process for the manufacture of composite, molded, thermoplastic articles comprising an insert member contiguous with a second body of molded thermoplastic material, is carried out in a mold assembly comprising a core member and a cavity member engageable therewith. The core and cavity members cooperate to define a first molding station having a first cavity for molding an insert member, and a second molding station which is configured to receive and support an insert member therein, and to provide a second molding cavity contiguous with the insert member for molding a thermoplastic body contiguous with the insert. At the start of the process, an insert is supported in the second station, and thermoplastic materials are injected into the molding cavities in the first and second stations so as to mold an insert and a completed, composite member. The core and cavity are separated, the completed, composite member removed, and the insert transferred from the first molding station to the second molding station, after which the core and cavity are reengaged and the process repeated. Also disclosed herein is an apparatus for carrying out the method.
