Abstract

PURPOSE:To simplify exceedingly preparation in comparison to conventional after-treatment system by giving metallic luster only to mark parts when a decorative substance is molded. CONSTITUTION:A female mold 1 and a male mold 2 are closed to form a cavity 3. The insert 4 of metallic color corresponding to a mark is set on the male mold 2. When transparent resin material is injected, a decorative substance in which a transparent resin molded body 5 and the insert 4 are combined in one body is obtained. When this decorative substance is seen from the surface side (arrow direction) the metallic insert 4 of metallic luster or the mark is seen through a transparent resin molded body 5. Parts excluding the mark of the back is coated generally with paint film. A press-molded piece of aluminum, stainless steel, copper, etc. and a resin molded piece of aluminum, stainless steel, copper, etc. are used suitably for the insert 4. Transparent polycarbonate, acryl resin or the like is used for resin material.
