PURPOSE:To efficiently produce a thin-walled molded product reduced in warpage and excellent in the advessiveness between a plurality of different laminated thermoplastic resin layers and surface appearance. CONSTITUTION:In an injection compression molding apparatus wherein a plurality of injection devices respectively injecting a plurality of different thermoplastic resins into a mold are connected to the mold, at first one thermoplastic resin is injected into the mold to perform injection molding. Subsequently, the mold is opened to form a gap 1.05-3.00 times, pref., 1.10-2.00 times the thickness of the thermoplastic resin to be subjected to injection compression molding next between the molded thermoplastic resin and the mold and the next thermoplastic resin is injected into the gap to perform injection compression molding to produce a thin-walled molded product wherein a plurality of the different thermoplastic resins are laminated. |
