摘要
介绍了一种基于横截面法的异型材挤出成型中熔体在模头内流动压力降的数值计算方法 ,可用于预测截面复杂的异型材挤出模头的压力降 ;
A numerical method for the calculation of the pressure drop in complex plastics profile extrusion die is presented,whic is based on the cross-section method and is very advantageous from a computational cost standpoint and suitable for industrial application.The validity and practicality of the proposed method is illustrated by one example.
