<p>Apparatus and method for forming hollow articles from plasticized materials are disclosed. A preform is partially formed under substantially no pressure on a preform core by introducing the core into a void-free charge of plasticized material that is placed in a preform cavity from a source of the plasticized material. After the preform core and preform cavity have moved together to define a preform mold space, the charge of plasticized material is subjected to a pressure forming step to form a completely packed preform on the core. The preform is then blow molded in a blow cavity by introducing blowing gas into the preform through the preform core. Neck mold structure that strips and releases the formed article from the core is also disclosed.</p> |
