摘要
本文对塑料异型材挤出模机头典型流道结构进行了分析，给出了塑料熔体在各种类型流道中停留时间的计算公式，并讨论了影响熔体停留时间的因素。
The structure of the typical channel in the extrusion die for Plastic Profile extrusion is analysed in this paper. The calculation formulae of residence time of the polymer melt is various channels are also given. And the influence factors on residence time are discussed.
