The technological characteristics of forged wheels are roughly as follows:

1. First heat the aluminum ingot to around 400 degrees Celsius, then it is ready for forging;

2. Hot forging and pressing, the higher the tonnage of the forging press requires the lower the working temperature of the aluminum ingot, the smaller the grain of the forged product, and the higher the toughness;

3. The temperature of the rough embryo formed by high temperature and high pressure is very high, and the surface is covered with black carbides, which must be handled by a fork motive. The rough embryo after pickling surface treatment already has the embryonic shape of a wheel hub;

4. After long-term reprocessing and heat treatment of the T4 and T6 heat treatment machines, the grains of the rough embryo will be firmer and the toughness of the product will also be improved;

5. Forged aluminum ring must rely on mechanical processing to process the rough embryo to the rim forming, so the work content includes bead forming, screw hole drilling, disk turning, detail processing and other steps;

6. Before painting, you must check the rim surface for flaws.
