Title: METHOD FOR PRODUCING METAL-IMITATING RESIN MOLDED MEMBER, METAL-IMITATING RESIN MOLDED MEMBER AND USE OF METAL-IMITATING RESIN MOLDED MEMBER
Abstract:
This method for producing a metal-imitating resin molded member is characterized in that: a high specific gravity resin material composed of tungsten and a resin is molded; the surface of the molded high specific gravity resin material is subjected to plating; the high specific gravity resin material is molded by injection molding; the weight ratio of tungsten is from 70% to 95%; the weight ratio of the resin is from 30% to 5%; the specific gravity of the high specific gravity resin material is 6 to 13; the resin is a nylon resin or a polyphenylene sulfide; and one or more substances selected from among zinc oxide, silica, talc, silicon, glass fibers, carbon fibers, aramid fibers and cellulose nanofibers are mixed into the high specific gravity resin material.
