Abstract: The production process that forming three-parts in a die for rear door outer panels was described. During the production, some bilateral symmetrial slip lines were obviously on the upper surface of the outer panel, which affected the surface quality of car body. By means of CAE simulation analysis and process optimization, the problem of slip line on the upper surface of the outer panel was solved. It summarized the control method for slip line in the production process of stamping parts with such structure.
