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, two body mold halves, and two neck mold halves. Each of the neck mold halves is attached directly to one of the die sets. The neck mold halves are configured to cooperatively form the exterior shape of the necks of one or more parisons. This type of neck mold attachment configuration can allow for better temperature control of the neck portion of the parison being molded therein. Further, such a neck mold configuration can reduce the cost of fabricating, installing, and/or replacing the neck molds.
