This study estimates the displacement of the bolster and slider having a few kinds of the adjustment methods at press forming by several EEM analysis and experiments, respectably. The methods of the adjustment have as follows, 1)Curved surface at the die and mold bottoms, 2) Lay with the shim plates, 3)With T- Blocks in T groove on the bolster. First and Second methods are adjusted according to the curvatures of the bolster in order to elastic deformation of the bolster at press that having it curvature or used various shim plates between the die and the bolster. In this report, a T-block method hardens the bolster or slider used to bury the part of the T grooves. As the results by several experiments and FEM simulations, development method could adjust the elastic deformation at the press forming.
