PURPOSE:To eliminate the terminal processing after molding by a method where in compressed air is blasted against the terminal part, which is projected from a cavity, of a skin material so as to curl it in the cavity at the closing of molds, to which the skin material is set. CONSTITUTION:A skin material 11 is set along a cavity surface 7 under the state that the terminal part 11a of the skin material 11 is set to be projected from a cavity 5. A movable mold 4 and a fixed mold 3 are parted from each other so as to make a gap l3 between them. The relationship l3<l2 is satisfied between the gap l3 and the projected width l2 of the terminal part 11a. Com pressed gas is blasted through pipes 21 against the terminal part 11a of the skin material 11 in order to curl the terminal part 11a inward of the cavity 5. By injectingly filling molten resin through a sprue 2 in the cavity 5 after the movable mold 4 and the fixed mold 3 are fully clamped together, the skin material is pushed from its back against cavity surfaces 6 and 7 and at the same time the resin is brought into close contact with the back of the skin material 11. Through the solidification of the molten resin, a core material is formed, resulting in obtaining a molded item on the core material of which the skin material 11 is integrally formed. |
