Abstract
An injection blow molding (IBM) system and method for forming a plurality of parisons and molded articles. The IBM system includes an injection station having two die sets and a plurality of first and second body mold halves each attached to a respective die set. Each of the first body mold halves has a corresponding second body mold half with which it cooperatively defines a cavity for forming the exterior shape of the body of one of the parisons. The individual, independent attachment of the body mold halves to the die sets allows easy individual replacement of faulty or worn molds. Further, such an attachment configuration also permits the body mold halves connected to a common die set to be spaced from one another, so as to reduce thermal expansion problems and ease dimensional tolerances required for the width of the body mold halves.
