However, if we exert the CAD/CAE technology on the design of extrusion dies, simulate the flowing state of plastics melt in die, and use computer to modify the design of extrusion dies, which will enhance the successful chances.

• 然而把CAD/CAE技术运用于挤出口模设计，模拟出熔体在机头流道内的流动状况，把试模过程放在计算机上进行，则可以大大提高试模的成功率。
