Abstract: The cause of dark pits, shuttle defects on skylight roof launder area and the solutions were expounded. Based on the analysis of stamping forming process, die structure, and die debugging, the optimization of process and die structure was adopted. Finally, it realized the controllable for dark pit and shuttle defects, which improved the vehicle surface quality.
Key words: skylight roof; launder; dark pit; shuttle; process optimization; structure optimization
