| Abstract | ||
| One of the most important factors that affect the hardness of formed products is forming tool design( drawing die profile). Die profile shape with other factors like reduction of area, forming temperature , friction... etc. Will produce a specific deformation mode that characterizes deformed metal by drawing process. This will have a direct effect on hardness of the drawn product .This was carried out by studying the final mechanical properties of the drawn products through dies with theoretical concepts(UCRHS, ACRHS , DCRHS , CMSR) and other with industrial concepts taper die ( = ) All at fixed reduction in area of 64% . The material used in this research is commercial pure copper . the drawing process was carried out at room temperature. Obtained results show that drawing die( CMSR) is the most efficient die design, at the same time, design of taper die ( = ) shows the lowest efficiency as compared with others.
