PURPOSE:To obtain a molded article high in heat resistance and durability without generating ill effects of metal, by performing molding after conductive coating containing nickel-coated graphite has been applied to the inside of a molding tool of a plastic case material. CONSTITUTION:A molding tool consists of a cavity mold 1 forming an outside surface and a cored mold 2 forming the inside. Conductive coating is applied to the surface of the cavity mold 1. As for a coating method, various methods are possible according to a kind of the conductive coating. The conductive coating is thermoplastic or thermosetting coating for which nickel-coated graphite is used as conductive powder. Along with a matter that the molding tool is clamped, a molten article of thermoplastic is injection and filled through a filling hole 3 and a case material 8 is molded, the coating which has been stuck peelably to the inside of the cavity mold 1 is trans-stuck on the outside surface of the case material and adheres strongly for unification. In a mold releasing process, the case material 8 wherein the coating 7 has adhered strongly for integrity is demolded. |
