What is the difference between forged wheels and cast wheels?
1 Answers
The differences between forged and cast wheels are mainly reflected in: 1. Different processes: In terms of mold selection, cast wheels use sand molds, while forged wheels use steel molds; cast wheels undergo natural cooling before mechanical processing, including deburring, surface repair, polishing, etc., whereas forged wheels are formed through stamping before mechanical processing. The casting technology determines performance. From a performance perspective, forged wheels have higher strength and lighter weight, while cast wheels have better filling properties, fewer casting defects, and higher density. 2. Different costs: The casting process is simpler and relatively lower in cost, while forging is more complex and thus more expensive to manufacture. In terms of price, wheels of the same model that are forged are usually much more expensive than those made by low-pressure casting. 3. Different weights: Forged wheels require continuous stamping to form, so after molding, their molecular structure becomes very compact, allowing them to withstand higher pressure. Therefore, forged wheels are lighter in weight than cast wheels of the same size and strength. In summary, the production process of forged wheels is more precise, making cast wheels somewhat inferior by comparison. As a result, high-end cars more often choose forged wheels.
