Steering Stop parts constituting the suspension system of automobiles are located inside an automobile suspension. They are used to fix upper and lower suspension arm parts by welding. The purpose of this study was to develop Steering Stop parts for automobile suspension. Cost increase due to problem of existing tool life is a challenging issue. This study tries to solve the tool life problem and reduce the cost using a former cold forging complex forming technology. We developed a long-life complex forming technology between multistage former forging and cold forging for producing Steering Stop parts of automobile suspension.
