Article Preview

Extrusion is one of the youngest processes in metal forming. In this proceeding the influence of the form and the angle of the die in the process of direct warm extrusion of aluminum is studied. Utilizing FEM and different forms of the curves of the die form, we have analyzed the various angles with the use of FVM; the improved angle and form of the die have been extracted from the findings. Having been modeled in the domain of Pro/Engineer, the dies are analyzed with the use of SuperForge2004 and Ansys6.1 softwares. To prove the correctness of the modeling and the analysis, we have compared our findings with available conclusions. So, with these methods we can model real industrial processes with minimum simplification and take effective steps in designing processes and reducing difficulties in manufacturing and improving the products.
