What is the Difference Between Forging and Casting?
1 Answers
The distinction between forged and cast wheels mainly lies in the manufacturing process, cost, and weight. Different Processes: In terms of mold selection, cast wheels use sand molds, while forged wheels use steel molds. Cast wheels undergo natural cooling followed by machining processes such as deburring, surface finishing, and polishing. Forged wheels, on the other hand, are shaped through stamping before undergoing machining. The casting technology determines performance. From a performance perspective, forged wheels are stronger and lighter, while cast wheels offer better filling properties, fewer shrinkage cavities, and higher density. Different Costs: The casting process is simpler and relatively lower in cost, whereas 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. Different Weights: Forged wheels require continuous stamping to take shape, which results in a very tightly packed molecular structure after forming. This allows them to withstand higher pressure, making forged wheels lighter in weight compared to cast wheels of the same size and strength. In summary, forged wheels have a more precise manufacturing process, making them superior to cast wheels. As a result, high-end vehicles often opt for forged wheels.
