It is also predicted that the orientation ratio responds to the diechannel length, the channel area expanding ratio of die and plastics melt viscosity.
此外还预测了扩张机头流道长度，面积扩张比、塑料熔体粘度对取向度也有影响。

Analyzing the diechannel structure and the melt flow of the circle profile in the extrusion die provides the basis of the die design for the circle profile.
分析了模头流道结构和熔体在圆环型材挤出模中的流量，为环类型材挤出模设计提供了依据。

The extrusion diechannel is composed of three sections: transportation section, transition section and dicing section. The functions based on CAE of the three sections have been clarified.
