Abstract
A process for crystallizing a thermoplastic preform or container which utilizes a preheated plug to provide the sole upright support for a workpiece in the crystallizing process. The preheated plug aids in the crystallization process by applying heat to the interior surface of the finish area while heat is also applied to the exterior surface of the finish area to crystallize the finish area. The thermoplastic preform or container is then cooled and removed from the plug.
