The process and advantages of forging wheels

The process of forging aluminum wheels is to use high pressure (mostly 10,000 tons of pressure) to press a piece of alloy that has been heated to nearly 500 degrees into a rough embryo (prototype) of the wheel, undergo a powerful cold spinning process, and then enter T6 Heat treatment, and then secondary processing with CNC detail engraving.

Due to the high pressure axial forging and the transverse super cold forging (spinning), the molecules between the alloys will be smaller, the gap will be finer, the density will be higher, and the interaction force between the material molecules will be stronger, so the wheel hub Only less raw materials are needed to achieve sufficient rigidity, making the overall weight lighter.

Because the metal is still in a solid state during forging, the shape cannot be as varied as liquid casting, and the body is plump. The appearance of forged aluminum wheels is mostly simple, thick lines. Forging can eliminate defects such as loose as-cast during the smelting process and optimize the microstructure. At the same time, due to the preservation of complete metal flow lines, the mechanical properties of forgings are generally better than castings of the same material. For the important parts of related machinery with high load and severe working conditions, forgings are mostly used except for simpler shapes that can be rolled, profiles or welded parts.

The advantages of forged aluminum wheels are: light weight and high rigidity.
