How Many Types of Wheel Manufacturing Are There?

[NadiaRose]

Wheels are manufactured through three methods: gravity casting, forging, and low-pressure precision casting. Below is a detailed introduction to wheel casting: Gravity Casting: This method involves pouring molten aluminum alloy into a mold using gravity. After forming, the product undergoes lathe processing and polishing 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. Forging: A whole aluminum ingot is directly extruded into shape on a mold using a thousand-ton press. The advantages include uniform density, smooth and fine surface finish on the product, thin and lightweight wheel walls, and the highest material strength, which is over 30% higher than casting methods. Low-Pressure Precision Casting: This method involves precision casting under a low pressure of 0.1Mpa. It offers excellent formability, clear contours, uniform density, and a smooth surface. It achieves high strength and lightweight while controlling costs, with a yield rate of over 90%.
