The parts with axial special-hole are widely used in many fields.But they are impossible to be manufactured by special processing and too difficult to be processed by common method because of the high cost and low efficiency.In this paper,a new practicable method of axial special-hole by open-die cold extrusion is discussed.The key parameters which largely influences forming process and the feasible limits are analyzed by numerical simulation with experimental research.Based on the analysis,the law of shaping and the limit of the key parameters are concluded..
