PURPOSE: To extremely simply produce the interior materials etc., of automobiles by stamping molding by bicolor-extruding a molten material of a soft resin and a hard resin on a lower mold and molding a laminated molded article comprising a soft resin layer and a hard resin layer by pressing a bicolor- extruded molten material with the lower mold and an upper mold. CONSTITUTION: In molding interior materials, first a soft resin 2 and a hard resin 3 are bicolor-extruded from an extruder 6 on a lower mold 4. The soft resin 2 is selected from acrylic rubber, butyl rubber, silicon rubber, urethane rubber, etc., and the hard resin 3 is selected from polypropylene, hard polyvinyl chloride, acrylonitrile-butadiene-styrene copolymer, etc. In a bicolor-extruded molten material 1, the lower side is the soft resin 2 and the upper side is the hard resin 3, and an interior material, for example a door trim, is molded by pressing with the lower mold 4 and an upper mold 5. In this process, since a hard resin layer 3A is a base material and a soft resin layer 2A is a skin material, a conventional skin material production process and a lamination process are eliminated. |
