company news about What is the aluminum alloy wheel preform shell and low pressure casting aluminum alloy wheel mold?

The company develops one kind of aluminum alloy wheel preforms the shell and the low pressure casting aluminum alloy wheel mold. The preformed Shell has an inner surface which is attached to the bottom of the upper die spoke in low pressure casting and an outer surface facing the die cavity, and is made of metal. The technical scheme of the utility model has the following advantages: solving the problem that the metal die is limited by the angle of the edge die, making the spoke root of the blank of the wheel thin, facilitating the casting forming, eliminating the original casting defects and improving the rate of finished products; removing the dull weight of the spoke root, lightweight the wheels.
