摘　　要：研究了在相同的挤出速度下不同机头温度对挤出小口径塑料软管(以下简称小管)成型尺寸的影响以及不同的挤出速度下温度对小管成型尺寸变化的影响,并阐述了温度在小管挤出中的重要性。试验证明,调整挤出机头的加热温度或调整挤出速度的大小,均能达到改变挤出管尺寸的目的。Effects of different head-temperature at the same extruding speed and that of different extruding speeds at the same temperature were studied respectively on the molding dimension of the thin and flexible tube. Tests showed that the adjustment of the head - temperature and that of the extruding speed can both result in the alteration of molding dimension of the extruding tube. The importance of temperature in the extrusion process was expounded.
