Abstract
PURPOSE: Thick-wall molded products with freeness from surface sink and void and with high dimension accuracy are produced by using top surface-opening built-up mold which is made of a mterial with double layered structure consisting of a heat-insulating material having a specific insulating effect and an inner surface material and cooling the mold at a low rate during heating the top surface.
