Abstract:
An injection blow molding apparatus and method produces articles by injecting a settable material at high pressure into the cavity of an injection mold to form a parison and then expanding the parison in a blow mold defining the configuration of the article. The injection mold defines intricate detail in the walls of the injection cavity and produces a parison with the detail formed thereon. Detail on the expanded portion of the parison is preserved in the blow mold and appears on the surface of the blown article without loss of definition.
