When comparing with other manufacturing technologies, the extrusion technology
always stands out as it is known to be highly efficient in terms of producing products of
superior quality with the least possible amount of wastage. With the ever-increasing cost
of materials, energy and the competition in the market, it becomes almost necessary to
device a model with the minimum number of trials and shortest lead time. A multi-hole
extrusion process was hence devised to serve the above needs. It employs a die with more
than one hole and is considered to be highly effective in micro-extrusion and producing
parts with smaller lengths and cross-section.
The present thesis mainly focusses on the multi-hole extrusion process. Previously,
various experimental analysis has been carried out to calculate the effects on process
parameters on the extrusion process as a whole.
In our present work, a finite element analysis software known as DEFORM 3D has been
used to simulate the proposed model prepared on AUTOCAD FUSION 360 and thus,
obtain the values for extrusion load and effective strain for multi-hole extrusion for
different multi-hole dies. The values obtained from FEA are compared with the
experimental results and a good agreement was observed.
