发明名称 MANUFACTURE OF MULTILAYERED MOLDING
摘要 PURPOSE:To manufacture a multilayered molding with a good appearance at a high cycle that has no creases and breakages in its skin material by securing a skin material on the upper mold or lower mold for molding through vacuum suction from the gap provided on the place corresponding to the non- product part of a multilayered molding in the upper mold or lower mold. CONSTITUTION:Between the not-yet-closed upper and lower molds 1, 2, a skin material 7 and molten thermoplastic resin 8 are supplied and then press-cooled so as to form a molding, at the same time, the molding surface is glued with the skin material 7. In this instance, a gap 5 is provided on the place corresponding to the non-product part of a multilayered molding in the upper mold 1 or lower mold 2. From this gap 5, the skin material 7 is secured and then molded on the upper mold 1 or lower mold 2 through the vacuum suction.
