Can Low-Pressure Cast Wheels Be Used for High-Speed Driving?

[JosephAnn]

Casting wheel strength is designed and calculated, and as long as they meet standards, there are no safety hazards. Below is relevant information: Gravity Casting Method: This method uses gravity to pour aluminum alloy solution into a mold. After forming, it is processed and polished by a lathe to complete production. The manufacturing process is relatively simple, requiring no precise casting techniques, resulting in low costs and high production efficiency. However, it is prone to bubbles (sand holes), uneven density, and insufficient surface smoothness. Many Geely models, especially earlier ones, use wheels produced by this method, though newer models have mostly switched to newer wheel types. Forging Method: An entire aluminum ingot is directly extruded into shape on a mold by a thousand-ton press. The advantages include uniform density, smooth and fine surface, thin and lightweight wheel walls, and the highest material strength—over 30% higher than casting methods. However, due to the need for more sophisticated production equipment and a yield rate of only 50-60%, the manufacturing cost is higher.
