Optimization of die design for thin-walled flat multi-port tube with the aid of finite element simulation

Die design plays a critical role in aluminum alloy profile production, which directly influences the quality of the final products and the service life of the die. In the present study, a porthole die for a multi-hole extrusion process of a thin-walled flat multi-port tube is designed and optimized through numerical simulations. The simulation results show that with the original die, the extruded tube has a non-uniform velocity distribution in...
