Abstract

In this paper, The experimental study on the crack during press forming of the door latch assembly for a vehicle door is performed. Length to be inserted into the conventional mold upper die punch is 20 mm, wherein the cracks are generated on the product surface and causes a secondary quality problem. In this study, the length to be inserted in the mold upper die punch 0 mm, 10 mm, 20 mm, which was changed to perform the experiment. Through the experiment, the length inserted into the mold can be seen that the upper die punch of the press forming conditions optimized when the 0 mm.
