Abstract

PURPOSE:To facilitate the secondary process by a method wherein the secondary processing mold and the secondary injection unit are arranged between the orientation blow molding station and the unloading station in an injection orientation blow molder intermittently rotating, and partial injection molding to blow moldings is carried out in succession to the orientation injection blow molding. CONSTITUTION:A battomed parison is molded in an injection molding station A and transferred to a temperature regulation station B by holding in a neck- mold. After regulating the temperature, it is transferred to the orientation blow molding station C and orientatively blow-molded to be a blow molding 15. Then, the blow molding 15 is clamped by the secondary processing mold 16 of the secondary processing station D. Thereafter, the injection unit 18 ascends and a cavity is formed surrounding the bottom part of blow molding 15 due to the ascent of the nozzle 20 and the bottom mold 21. In addition to this, compressed air is blown into the blow molding 15, and resin is injected surrounding the bottom part. Thus, the secondary process can be easily carried out.
