ABSTRACT:
A method for producing an inner shell used for a disc cartridge in which an optical disc, an inner shell and shutter members are housed in a main cartridge body unit. The inner shell provided in the main cartridge body unit includes a first molded portion, provided with an aperture, a second molded portion having a resin injection port and molded at a position where the aperture is formed, and a flanged thin-walled section connecting the first and second molded portions to each other. The method includes the steps of injecting molten resin into a cavity defined by a fixed metal die and a movable metal die for molding the first molded portion, the second molded portion, and the flanged thin-walled section, and severing the flanged thin-walled section by a punch provided to the movable metal die before the molten resin injected into the cavity is cooled and solidified.
