Advantages of forged wheels

Forging is currently the most advanced production method under mass production of wheels. The forged wheel hub is a piece of 6061 aluminum alloy billet heated under a certain pressure and repeatedly forged into a wheel hub blank by a large forging press.

After forging and pressing, the blank is processed by spinning. The effect of this process is to stretch the width of the rim to reach the corresponding specifications. After spinning, the hub has been basically formed, and then processed by machine tools, after polishing and painting. Get the finished wheel hub.

It is precisely because of the continuous stamping that after forming, its molecular structure will become very tight and can withstand higher pressure. Therefore, under the same size, forged wheels are lighter, stronger and stronger than cast wheels. .

Because the forging technology is complex and the forging equipment is expensive, the cost of purchasing some large forging presses is tens of millions, so the cost of forging wheels is relatively high. Forged wheels are basically used in high-end cars and commercial trucks that pay attention to handling, especially those high-performance supercars that use large-size, multi-model forged wheels without exception!

The casting wheel hub refers to the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling, solidification and cleaning, a casting (part or blank) with a predetermined shape, size and performance is obtained.

Disadvantages: long casting time, long time-consuming feeding and mold changing, large equipment investment, insufficient toughness of wheels using this process, loose metal molecular structure, large gaps, and easy to break when impacted.
