Abstract: The CAE-oriented parametric model of extrusion die is established by the integration of proportional spacing method and ray tracing method. The pressure distribution and velocity distribution in the runner are educed through the three-dimensional numerical analysis of the parametric model. Based on the results of finite element analysis and the parametric modeling of the runner, some important structure parameters of die are optimized. The optimization objective of the model is that the average current velocity of each domain in the cross sections of extrusion profile is equal. The optimization results could be mapped to the parametric model directly. And the integration of CAD/CAE is fulfilled directly. Last, the correctness and validity of the method are illustrated through a case.
