| Abstract: | The die of square-shaped plastics profile being taken as an example,the geometry,mathematic and finite element model were established,and numerical simulation and analysis were performed.Besides,how to effectively apply the function of POLYFLOW inverse extrusion to design the square-shaped plastics profile extrusion die was discussed.The research indicated：the function of POLYFLOW inverse extrusion can forecast its distortion tendency ahead of time and enhance the success ratio to design the disposable profile extrusion die.It reduces the design cycle time and the cost of development. |
