MOLDING APPARATUS AND PROCESS EMPLOYING HEATED FLUID

摘要

A molding apparatus and method for forming a thermoplastic shell or skin product. The molding apparatus includes a hollow mold housing provided with a mold tool thereon, which together define a fluid chamber within the mold housing. A quantity of heated liquid is supplied at a predetermined or operating temperature to the chamber of the mold housing from a liquid supply via an elongate feed pipe until a rear surface of the mold tool is covered. The mold housing is then oscillated to uniformly distribute the heated liquid within the chamber and to effect uniform heating of the mold tool. Heating devices are located within the chamber of the mold housing to add heat to the liquid within the housing chamber to maintain a desired liquid temperature.
