  • Patent number: 4379688
    Abstract: An injection blow molding apparatus capable of achieving biaxial orientation and the produced article is disclosed. The apparatus features a transport table rotatable about and reciprocally movable along its center axis and at least an injection molding station and a blow molding station positioned adjacent to and around the transport table. There is at least one core rod mounted to the transport table, which core rod is moved from the injection molding station to the blow molding station by the table movements. The core rod coacts with the injection molding station to form an injection molded parison which is transported on the core rod to the blow molding station. At the blow molding station, a stretch pin mounted within the core rod is utilized to aid in the biaxial orientation of the final article blown at the blow mold station.
