What is the Difference Between Forged and Cast Wheels?
1 Answers
The distinction between forged and cast wheels mainly lies in the manufacturing process, cost, and weight. Here are the detailed specifics: 1. Different Processes: In terms of mold selection, cast wheels use sand molds, while forged wheels utilize steel molds. Cast wheels undergo natural cooling before mechanical processing, including deburring, surface finishing, and polishing. Forged wheels, on the other hand, are shaped through stamping before mechanical processing. The casting technology determines performance. From a performance perspective, forged wheels offer higher strength and lighter weight, whereas cast wheels exhibit better filling properties, fewer shrinkage cavities, and higher density. 2. Different Costs: The casting process is simpler and relatively cheaper, while forging involves more complex procedures, resulting in higher manufacturing costs. In terms of pricing, forged wheels of the same model are typically much more expensive than low-pressure cast wheels. 3. Different Weights: Forged wheels require continuous stamping to form, which results in a very dense molecular structure after shaping, enabling them to withstand higher pressure. Therefore, forged wheels are lighter in weight compared to cast wheels of the same size and strength. In summary, the production process of forged wheels is more precise, making cast wheels somewhat inferior in comparison. As a result, high-end vehicles more commonly opt for forged wheels.
