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

[VanOscar]

Casting wheel strength is calculated through design, 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, the wheel is processed and polished on a lathe to complete production. The manufacturing process is relatively simple, does not require precise casting techniques, and is cost-effective with high production efficiency. However, it is prone to bubbles (sand holes), uneven density, and insufficient surface smoothness. Many early models from Geely used wheels produced this way, though newer models have mostly switched to updated wheel designs. Forging Method: An entire aluminum ingot is directly extruded into shape on a mold using a thousand-ton press. The advantages include uniform density, smooth and refined surfaces, thin and lightweight wheel walls, and the highest material strength—over 30% higher than cast wheels. However, this method requires advanced production equipment, has a yield rate of only 50-60%, and incurs higher manufacturing costs.
