ResumoA plastic cold joining method of a rotor shaft with a flange was developed to produce automobiles axle parts. In this process, a high strength shaft with serrated teeth was indented into the hole of a thick disc at room temperature. The serrated shaft acts as a tool to indent to the hole. Since the disc with the teeth-shaped hole was strengthened by work hardening, the yielding strength of the join was 1.5 times as high as that of a joint produced by metal cutting. Those conditions and mechanism were experimentally determined.
