Forging
In the forging process, the aluminum alloy bar (6061/7075) is first forged into a forging billet through a multi-stage forging process. The raw material is processed and shaped several times in a forging press with a force of about 10,000 tons. At the same time, it must be heated repeatedly (T6 heat treatment). In the first stage, the rod is compressed into a disc. In stage 2, the disc is pressed into the shape of a narrow forged billet of specific dimensions. The rims are designed with suitable blank drawings, then turned and milled on CNC machines.
Forging technology can produce wheels of exceptional strength. The complex forging technique results in a higher material density of the light metal alloy, which ensures higher strength compared to conventional casting techniques. Potential pores and cavities are eliminated. Material thickness can also be chosen to be lower than casting and flow forming wheels. Due to the thickness of the material, the correspondingly finely machined forged alloy wheels are noticeably lighter and more refined. The resulting reduction in unsprung mass contributes significantly to improved driving dynamics.
