Surface deflections are generally occurred in door outer handle area or fuel injection area where the shape of its section is changed suddenly. Usually, their basic cause is compressive stress occurred in forming process because of different touching time between die and panel. Surface deflection amounts can be reduced with sub pad which is pressing down around handle area prior to forming concave door handle. New die structure with it is developed and applied to minimize surface deflection amounts through the forming analysis, springback analysis, comparison of surface deflection amounts depending on the parameters and analysis of distances between sub pad and punch depending on padding forces. To analyze effectively surface deflection occurred around door outer handle area, die of door outer panel is manufactured partly containing door handle area. And to determine its proper size, the preceding investigation is executed through the simulations. To compare surface deflection amounts with typical dies and suggested dies with sub pad, simulations according to the process of surface deflection analysis are executed and then 3D scanning is preformed with stamping panel to verify effect of sub pad.
