Paper Title:
Numerical Analysis of Four-Hole Extrusion of Aluminum Alloys
  Abstract

The work presents the results of FEM simulations of extrusion process with the use of four – hole dies of various geometry. The traditional flat dies and pocket dies were adopted for comparison. The calculations were conducted for indirect extrusion of rods of 14 mm in diameter from the 6061 aluminium alloy. The distributions of strains, stresses, metal velocities and temperature within the deformation zone were the basis for metal flow analysis. Based on the conducted calculations the die configuration, leading to the best product quality was recommended. The product quality was evaluated by the flow direction of rods from the die orifices.
