초록
This study was researched to improve the quality and to reduce the defects of the Indenting shape of bottom chassis, which is one of the B.L.U (Back Light Unit) parts. Experiment result is the formation of the Indenting shape must be carried out by two forming processes. It was found that the forming one-step shape is an important factor in determining whether or not the two-step shape will succeed. When the shape of the forming pad is set to a convex shape such as a triangle, there is a good flow of material at the bottom. As a result, the thickness of the sidewall of the product becomes thick and the sidewall is formed vertically. In this respect, it was considered that the Indenting shape was excellent.
