For a easier bolt molding, an extrusion process, the 2nd step of the molding process, was moved to step 4, and the bolt head section was exclusively molded in steps 2 and 3. As a result, the molding process was made easier thanks to the minor modification, and the contact pressure decreased in step 1 and increased in step 2 over its earlier intensity. Also, the maximum effective stress, effective strain, and molding force were all increased in both steps 1 and 2.
