In the recent years, weight reduction of the vehicle is one of the major methods for improving automotive fuel efficiency. The use of low-density material such as high-strength aluminum alloy in the automotive industry is increasing every year. In this study, the aluminum extruded profile is analyzed by two bending processes using a commercial finite-element code (DEFORM-3D) in order to evaluate the press bending process. The first method is using the side-punch and the second method is the press bending process using the wing-die. From the results of FE-analysis, the distribution of the effective strain has been compare the wing-die bending process with the side-punch bending process. Especially, sagging phenomena have been predominant in the side-punch bending.
