Because the hub cast by spinning integrates various process characteristics such as forging, extrusion, stretching, bending, ring rolling, transverse rolling, rolling and the like, the cast product has the advantages of high quality, good flexibility, light weight and the like. The hub subjected to spin forming can keep the density of metal and the dynamic balance of the whole hub, so that the hub has enough rigidity, and meanwhile, the thickness of the material can be obviously reduced, and the hub becomes lighter and more durable. Compared with the aluminum alloy hub produced by common low-pressure casting, the weight of the hub with the same size can be reduced by 15 percent.

However, through the wheel hub of spinning casting, bear great pressure in the shaping stage, especially the clearance with the upper mold core of spinning upper mould after the spinning is finished is very little, leads to having the phenomenon of taking off in the drawing of patterns in-process, even has the condition of not drawing of patterns, not only reduced production efficiency, but also can cause the influence to product quality, increase the defective rate.
