摘要： High production injection blow molding by constantly traveling a series of cored blow cavity molds in a closed path, and by injecting plastic to form parisons (blanks) on the cores in the blow cavity molds while the latter are open. The injection is done by means of cavities in an injection cavity mold having a short synchronized travel with each blow cavity mold in turn, the blow mold cavities thereafter closing, the molded articles being formed by air under pressure directed through the cores into the parisons; curing (cooling), ejecting, and completing the closed path for continuous production without the use of intermittent steps.
