摘要： A method of extruding a homogeneous plastic rod substantially free of shrink voids, the method having the steps of: extruding a rod central portion of plastic material having a glass transition point and a Vicat softening point below the glass transition point, the rod central portion having a center core and an outer skin; cooling the rod central portion while maintaining the outer skin above the Vicat softening point until the center core is cooled to approximately the Vicat softening point; using an extruder to extrude around the rod central portion a sheath of the same plastic material, the sheath having an outer skin and inner and outer portions, such that the rod central portion acts as a heat sink for the inner portion of the sheath, and such that, at the extruder, the plastic material forming the outer skin of the rod central portion is melted upon contact with the plastic material forming the sheath and the plastic material of the rod central portion and the plastic material of the sheath form the homogeneous rod, and such that the plastic material forming the center core of the rod central portion remains at a temperature below the glass transition point; and cooling the sheath while maintaining the outer skin of the sheath above said Vicat softening point until the inner portion is cooled to approximately the Vicat softening point.
摘要翻译：一种挤出基本上没有收缩空隙的均匀塑料棒的方法，所述方法具有以下步骤：将具有玻璃化转变点和维卡软化点的塑料材料的棒中心部分挤出到玻璃化转变点以下，棒中心部分具有中心芯和外皮; 冷却杆中心部分，同时保持外皮高于维卡软化点，直到中心芯冷却至大约维卡软化点为止; 使用挤出机在棒中心部分挤出相同塑料材料的护套，护套具有外皮和内部和外部，使得杆中心部分用作护套内部的散热器，以及使得在挤出机中，形成杆中心部分的外皮的塑料材料在与形成护套的塑料材料和杆中心部分的塑料材料接触时熔化，并且护套的塑料材料形成均质棒并且使得形成杆中心部分的中心芯的塑性材料保持在低于玻璃化转变点的温度; 并且将护套的外皮保持在所述维卡软化点之上，直到内部部分被冷却到大约维卡软化点为止。

摘要： A method of manufacturing an etched extrusion, the method comprising the steps of extruding a thermoplastic material to produce a hot extrusion, and contacting the extrusion, while the extrusion is still hot, with a mixture of at least two fluids having different thermal conductivities so that the extrusion develops an uneven outer surface due to different rates of shrinkage caused by the different thermal conductivities.
摘要翻译：一种制造蚀刻挤出物的方法，该方法包括以下步骤：挤出热塑性材料以产生热挤压，并且在挤出仍然是热的同时使挤出物与至少两种具有不同热导率的流体的混合物接触，使得由于不同的热导率引起的收缩率不同，挤出产生不均匀的外表面。
