    摘要： A molding method and an injection-compression molding machine provided with an opening/closing valve between an injection unit and a metallic mold for achieving said molding method, in which in order to make the density of molten resins uniform and thus produce stable molded products, said valve is closed to carry out the preliminary pressing within the injection unit before the molten resin is injected into the metallic mold and then the molten resin is pressed within the metallic mold during or after the injection. This molding machine is arranged in a molten resin passage (46) provided between the injection unit (10) and the metallic mold (30) so as to be opened and closed and provided with the valve (40) for closing said passage and changing a sec. tional area of said passage.
