Abstract：

The exit velocities in the process of aluminum profiles extrusion appear to be the most important parameters for optimal die design. Incorrect die design is one of the reasons for different velocities in profiles. To receive extruded product with high quality, it is necessary to know the arrangement of the velocity profile at the outlet of die. The deformation process of aluminum profiles is simulated by finite element software, DEFORM-3D ,which gives us an opportunity to get exit velocities of profiles before the manufacturing of die. Numerical simulation results are confirmed by experimental procedure in real production conditions, which is very important for optimal die design process.
