Abstract
An injection blow molding (IBM) system and method for forming a plurality of parisons and molded articles. The IBM system includes at least one upper body mold half and one lower body mold half, with the upper and lower body mold halves cooperatively presenting a body cavity and being configured to define an exterior shape of a body of the parison. The tooling additionally comprises at least one upper neck mold half and one lower neck mold half, with the upper and lower neck mold halves cooperatively presenting a neck cavity and being configured to define an exterior shape of a neck of the parison. The tooling further comprises an upper thermal barrier plate positioned between the upper body mold half and the upper neck mold half and a lower thermal barrier plate positioned between the upper body mold half and the upper neck mold half.
