CNC machining of high quality cast alloy wheels
The manufacturing process of aluminum alloy wheels includes smelting, casting, heat treatment, machining and painting and other main processes. In the smelting process, it is the key to control the composition, hydrogen content and temperature of the liquid aluminum. In the casting process, the liquid aluminum temperature, mold temperature and cooling parameters need to be strictly controlled. Heat treatment is designed to improve the mechanical properties of castings and eliminate internal stress. CNC machining is usually used, and the key control items include center hole diameter, PCD position, end diameter jump and dynamic balance. Coating is designed to improve the reliability, durability and appearance of the wheel decoration.
