The plastic forming process of crankshaft was simulated by software DEFORM and orthogonal test principle combined with four factors of mold parting surface rounded corners (R), the length percentage, width percentage and height percentage of cavity for pre-forging and final forging. Through the range analysis, the influence order of plastic deformation load on crankshaft is height percentage, length percentage, width ratio and R.The results show that in the plastic processing of crankshaft pre-forging, the maximum forming load is 3.63×107 N and the optimal design is mold parting surface rounded corners R of 8 mm, the length precentage of 0.998, width percentage of 0.98 and height percentage of 1.12, while in the final forging, the optimal design is mold parting surface rounded corners R of 8 mm, the length percentage of 0.998, width percentage of 0.95 and height percentage of 1.09.
