To get the steady interface, the ratio of coextrusion flow length to height is at least l-1.5._The role of smooth flow zone is important to reduce the pressure-fall. The higher surface quality of the fluid path can make the velocity field more uniform and the interfacial offset less. However, the layer interface position was almost unaffected by the convergence angle, so for the convenience of die manufacture and extruder\'s collocation, it is fit to make the contact angle as 90°with smooth corner.

在模具结构参数中，共挤出流道的长度和模具壁面光滑程度对界面有重要的影响，根据计算结果得到了方形流道共挤出段长度与高度比的取值范围；而模具入口收敛角对界面的影响不大，在实际生产中为了模具制造和共挤出机布置的方便，可采用圆滑过渡的90°入口角。
