In this study, the effect of upper die type on the load characteristics of lower die and the wasted material was studied numerically. The different shapes(A-type, B-type, C-type) of upper die were applied and finite element analysis method was applied for the analysis in each stage. The half of X, Y plane was analyzed due to the symmetrical shape in order to reduce the analysis time. The coefficient of friction was set to oil_cold conditions as refer to the system library. It was revealed that principal stress was the order in A, C, and B. A and B type have the highest value in 4 stage, and C type shows the highest value in 3 stage. In addition, Von mises stress were higher in order A, B, and C. A and B type have the highest in 4 stage, and C type shows to have about the same value in the 2 - 5 stage. The load was generally higher than C type. The load of C type was reduced in YY-direction at each stage without 2, 5, 6 stage.
