| description | PROBLEM TO BE SOLVED: To provide a method for producing a hollow pipe with improved cooling efficiency.SOLUTION: The method for producing a hollow pipe of the present invention comprises a shaping step and a cooling step. In the shaping step, a thermoplastic resin is shaped to obtain a hollow tubular resin. In the cooling step, a cooling fluid is circulated between hollow interior and outside of the hollow tubular resin to cool the hollow tubular resin from the inner wall. This constitution enables the cooling fluid to be continually replaced by generating a circulation flow actively in a wide range of the hollow interior of the tubular resin, thereby resulting in efficient cooling of the tubular resin.SELECTED DRAWING: Figure 1
【課題】 冷却効率が向上された中空管の製造方法を提供する。【解決手段】 本発明の中空管の製造方法は、賦形工程と、冷却工程と、を含む。賦形工程では、熱可塑性樹脂を賦形し、中空管状樹脂を得る。冷却工程では、中空管状樹脂の中空内部と外部との間で冷却用流体を循環させて、中空管状樹脂を内壁から冷却する。この構成によって、中空管状樹脂の中空内部の広い範囲において積極的に循環流を生じさせることで、冷却用流体を絶えず交換することができるため、中空管状樹脂が効率よく冷却される。【選択図】図１ |
