Abstract

Design of forming tool (Extrusion die) is one of the most important factors that affect the mechanical properties of formed products (specific tension) . Other factors as die profile along ,friction,temperature and reduction of area will produce aspecific deformation mode that affect on the mechanical properties of the extrusion product . The aim of this research to study the efficiency of extrusion dies on the basis of both theoretical design concepts (CRHS, CMSR) and industrial concept (TAPER ) . This research studied final tension property of the extrusion products through these dies with theoretical concepts and industrial concept .The reduction of area of all this dies is (50%) . The results show that extrusion die (CMSR) is the most efficient die in design ,at the same time ,design of taper die show lost efficiency .
