发明名称 METHOD FOR MOLDING RESIN MOLDED ARTICLE
摘要 PROBLEM TO BE SOLVED: To provide a resin molded article molding method that is less restricted by the kind, material, and properties of a thermoplastic resin and can mold a thin resin molded article having high flatness and a uniform thickness.SOLUTION: In a resin molded article molding method for molding a transfer-molded resin molded article by applying a molten resin, supplied from an in-line screw type injection plasticizing device, to a mold while discharging it from a T-die, and cooling and solidifying the molten resin, the molten resin is pressurized by moving forward a screw by a predetermined amount (screw pressurizing stroke) before the application of the molten resin to sufficiently increase pressure in the T-die and the injection plasticizing device flow pass and make the pressure distribution uniform, and then the application of the molten resin to the mold is performed by relatively moving the T-die with respect to the mold while maintaining an application distance between a resin discharge port of the T-die and a stamper at a thickness substantially same as that of the resin molded article.SELECTED DRAWING: Figure 1
