Abstract

In this research, the extrusion of copper and aluminum in cylindrical forms was investigated by finite element simulation. In addition, the effect of angle and internal profile of the mold on the extrusion force and dimensional uniformity of the produced part was investigated using two types of molds with conical and curved geometry, and its effect on extrusion force was examined by changing the friction coefficient. Based on the results, increasing the conical mold's profile angle leads to an increase in dimensional non-uniformity in the piece and increases the extrusion force. Conversely, the use of curved molds lead to reduction of extrusion force and dimensional uniformity. Interchanging the material of the core and shell can also affect the extrusion force and diameter. Furthermore, curved molds use leads to close the copper core/aluminum shell extrusion product and affect the extrusion force and dimensional changes. Based on investigating the effect of friction coefficient, extrusion forces were increased by increasing the coefficient and shear stress of material flow. The results were compared and validated with similar experimental research.
