The company has developed a low pressure casting method for preformed aluminum alloy wheel shell and aluminum alloy wheel. The invention provides an aluminum alloy wheel preform Shell, which is characterized in that the preform shell has an inner surface which is adhered 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 proposal of the invention has the following advantages: solving the problem that the metal die is limited by the drawing angle, 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; Lightweight the wheels.
