The fabrication of aluminum alloy products through the hot extrusion process has been a forwarding and promising method for most manufacturing industries. In the extrusion process, process enhancement has been taken care of to improve the productivity of the multi-hole extrusion process. Since the improper selection of process parameters leads to poor quality and yield, an attempt was made to simulate hot direct extrusion of AA6063 alloy using DEFORM-3D, the optimal process parameters were selected through Taguchi-based grey relational analysis with a multi-response optimization technique....
