塑料熔体的流量分析与圆环型材挤出模的设计

The Flux Analysis of the Plastic Melt in Extrusion Die Circle and Construct Design Channel

塑料异型材的加工是通过挤出成型的。塑料熔体在挤出模中的流动状态分析是挤出模设计的基础。塑料异型材加工的模具尽管种类很多,形状各异,但都可视为圆环和孔隙的组合,分析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打下了基础。

The plastic profile is produced with extrusion die. The flow state analysis of the plastic melt in extrusion die is basisof extrusion die design. There are many kinds extrusion dies. Their shapes are difference, but all can be combine by circle andlire. It is base of the circle plastic profile extrusion die design to analyses the flow channel structure in the extrusion die and theplastic melt flow sate in circle flow channel.
