Abstract :
Extrusion process of a large diameter thin-walled aluminum profile was simulated by FEM based on Deform-3D software. The results show that the material flow velocity in the bearing exit of the original designed die is non-uniform. Three times modifications were performed and simulated. The optimal design with more uniform flow velocity in the bearing exit was obtained.
