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 two mold half assemblies. Each of the mold assemblies is attached to one of the die sets. The mold half assemblies are configured to cooperatively form the exterior shape of the necks of a plurality of parisons. Heat transfer channels formed in both the die sets and the mold half assemblies are fluidly connected with each other, such that a heat transfer fluid can be routed to the mold half assemblies via the die sets.
