The anisotropy of sheet metal is important in bendability. The anisotropy in cold rolling sheets appears by the alignment of impurities, inclusions, and voids. The material ductility is reduced by this anisotropy. This anisotropy leads to cracks. Therefore, it is important to consider this anisotropy when designing progressive die. A automatic production system was developed for high productivity and safety. The conventional semi-progressive die is unfavorable for safety, material saving and high-speed production. By introducing two array type new progressive die for automobile door checker mount bracket, four times productivity more than conventional production methods is achieved. The press die parts solid modeling system is built by using Pro-Engineerⓡ through this research and verified allowable tolerance and possibility of assembly and disassembly of parts. Therefore, die manufacturing time and cost was reduced. The conventional die can produce 1000 products per hour, but new progressive die is able to produce 2000 an hour. The manufacturing cost curtailment effect is accomplished more than 40% in comparison with traditional method.
