Optimization Design of Extrusion Die Channels for Polymer Profile

The objective function is the same flow speed of each sub-filed of product section at exit of the extrusion die for the complexity of hollow polymer profile, and design variables are impact on the flow uniformity of the space above the compression, the example based on finite element numerical simulation and based on the CAD/CAE/ERP database system, the result showed the velocity is obviously improved after the optimization, well positioned to meet the requirements of customer.
