초록

A process and multistation apparatus for injection blow molding a thermoplastic material to form a blow molded container having an integral injection molded handle is disclosed. The process and apparatus feature an injection mold which is closed to form an injection mold cavity with a contiguous injection mold handle cavity. A preform pin is inserted into the injection mold cavity through a preform carrier to form a preform recess into which hot thermoplastic is injected to form a hollow preform having a solid injection molded handle. After cooling the t...
