  • Publication number: 20020172736
    Abstract: An injection press for molding pieces of elastomer comprises a fixed platen, a moving platen, and a turret carrying a plurality of molds, the turret and the molds being interposed between the two platens so as to be capable of being clamped between them in order to close the molds, and the turret being mounted to rotate so as to move each mold sequentially between an injection station, vulcanization stations, and an unmolding station. The press also comprises an injector device adapted to inject elastomer into each mold while it is in the injection station, heater devices adapted to heat the molds, and a control device adapted to move the moving platen and to cause the turret to turn.
