This invention substantially improves the surface finish on resin filled foamed molded plastic products manufactured by injection molding by preheating the skin surface (70, 72) of that of the mold in contact with the part to be molded prior to the injection cycle of the machine and then subsequently chilling the mold via internal tube connections (124, 126) to shorten the time needed in the manufacturing cycle for solidifying the part sufficiently for release from the mold. |
