Abstract

PURPOSE: To easily remove the burrs of resin formed in case of molding, by treating the whole surface or a specified surface of a thermal hardening resin molding metal mold surface with a compound body obtained by treating a specified, metallic matrix with a polymer belonging to a system containing fluorine.
CONSTITUTION: The whole surface of a thermal hardening resin molding metal mold surface or an air vent portion or the like is treated with a compound body gained by burying, by dispersion-eutectoid executing or by impregnating a polymer belonging to a system containing fluorine, such as, tetrafluoroethylene resin, etc. into a metallic matrix, such as, hard chrome plating or nickel-phosphor alloy plating or the like. For example, only an air vent portion 7 is lower-portion shaved in a steel material of a cavity portion of a metal mold, hard-chrome plated in a thickness of approximate 50μ and tefloc worked. A cavity portion 6 is formed by means of discharge working and ground, a gate portion 4 is worked and the cavity portion 6 and a plane portion are hard-chrome plated in the thickness of approximate 5μ.
