Manufacturing Process
Forged wheel manufacturing process
The manufacturing process of forged wheels involves several intricate steps. Initially, a solid piece of aluminum or magnesium alloy is heated to a high temperature, which softens the material. It is then placed under immense pressure using hydraulic presses or hammers, forcing the metal to take the shape of the wheel mold. The intense pressure compresses the grain structure of the metal, resulting in enhanced strength and durability. After forging, the wheel undergoes machining to create the necessary features and mounting points.
Cast wheel manufacturing process
In contrast, the manufacturing process for cast wheels involves pouring molten metal, typically aluminum or steel, into a mold. The molten metal is allowed to cool and solidify, taking the shape of the mold. Once the metal has hardened, it is removed from the mold, and any excess material is trimmed off. Cast wheels are generally simpler and quicker to produce compared to forged wheels, making them a more cost-effective option. However, the casting process can result in a less dense material structure and decreased overall strength.
