Abstract:
An injection stretch blow molding method, comprising:an injection molding step in which preforms are injection molded in an injection molding station; a step for inserting the preforms from the injection core mold into cooling elements surrounding the exterior surface of the preforms; a step for cooling an exterior surface of each of said preforms, after injection molding said preforms, in said cooling elements; a movement step for simultaneously transferring all of the preforms from the cooling elements to an intermediate circulatory carrier; a step for circulating all of the preforms on the intermediate circulatory carrier; and a delivering step in which said preforms are delivered by a delivering mechanism to carrying members of a blow molding circulatory carrier from said intermediate circulatory carrier; and a blow molding step in which said carrying members, supporting said preforms, are circularly carried and said preforms are stretch blow molded into containers in a blow molding station.
