ABSTRACT
Injection blow molding combines injection molding with blow molding, thus resulting in injection blow molding. The injection phase uses either a vertical plastifier or a horizontal plastifier to take the thermoplastic resin from the plastifier’s hopper and convey it into the heated barrel containing a screw for mixing and melting the thermoplastic material into a homogeneous melt, ready to be injected into a heated manifold. The heated manifold maintains the homogeneous melt and distributes it to the injection cavities of the parison injection molds. The parison injection molds contain the parison shape and are closed onto a metal core rod, which is centered in the parison injection mold. The metal core rods are mounted onto the rotating horizontal rotating table by retainers and a face bar. Once the homogeneous melted thermoplastic material is injected into the injection parison mold, the injected material is cooled so that the outside skin of the injected parison will not fracture on the opening of the injection parison mold.
