Experimental and Numerical Study of Multi Hole Extrusion Process

The main objective of the present work is the study the experimental and numerical study of multi hole extrusion process for making circular rods. The pure lead is used as extrude material for extrusion. The die consists of 5 holes with 5mm diameter. For prediction work, process has simulated using a Finite Element Method (FEM) code metal forming software DEFORM-3D®. All the experimental work and simulation are done at ambient conditions. The maximum load and maximum ram displacement are calculated for circular rods during the experimental work. From the results, it is noted that the behavior of load vs displacement is almost same for both experimental and numerical study of multi hole extrusion process. This study becomes illustration the behavior of the other tough materials by which one can understand the extrusion behavior of nonferrous materials.
