Abstract:
Method of making grooved, bell-ended thermoplastic pipe. In order to remove the core from undercuts, most of the molded article is cooled until substantially rigid while the bell-end is cooled more slowly. The article is ejected from the mold while the bell end is still soft enough to be deformed during ejection but recovers its shape after removal from the mold.
