To cope with this challenge, German automotive manufacturer Adam Opel AG, in cooperation with ThyssenKrupp System Engineering and the ESI Group, carried out an extensive development project. The team developed a solution approach in which an increased geometrical stiffness of the component was achieved by means of a double S profile instead of the conventional die radius. With ESI PAM-STAMP, the team was able to precisely predict the influence of the size and shape of the punch on the opening of the frame, the spring back and the twisting of the finished component.
