    • Apparatus for making open-ended thermoplastic tubular articles, which are dimensionally stable up to elevated temperatures comprises a fixed, heated external mould (12) and cooled mandrel (10), which is vertically displaceable relative to the mould (12). An open-ended polymer tube is disposed between the mandrel and mould and both its ends clamped to restrain the tube axially. The polymer tube is radially expanded into contact with the hot mould and maintained in contact for a time sufficient to ensure dimensional stability, and then allowed to shrink back into contact with the cooled mandrel, which is maintained at a temperature below the glass transistion temperature of the polymer. The resulting article is then stripped from the mandrel.
    • 用于制造开口端热塑性管状制品的装置,其尺寸稳定至高温包括固定的加热的外部模具(12)和相对于模具(12)可垂直移动的冷却的心轴(10)。 开口聚合物管设置在心轴和模具之间,并且其两端夹紧以轴向地限制管。 聚合物管径向膨胀成与热模接触,并保持接触足以确保尺寸稳定性的时间,然后使其收缩回与冷却的心轴接触,冷却的心轴保持在低于玻璃化转变温度 聚合物。 然后将所得制品从心轴剥离。
