Design of a multi-hole extrusion process

This work describes the procedure for the design of a multi-hole extrusion process. For the same sizes of the holes, the ram force in a single-hole extrusion process is more than in a multi-hole extrusion process. Therefore, a simplified upper bound and slab method analysis has been carried out for a single-hole extrusion process. The ram and die pressures obtained from this analysis are used for designing a multi-hole extrusion process setup. The stresses in the die are computed using the finite element method. Based on this approach, an experimental setup was fabricated and experimental study was carried out.
