What are the differences between forging and casting of aluminum alloy wheels?
The forging is the use of steel mold, the heating softened aluminum block placed in it, stamping method to shape it, after cooling, and then made by mechanical processing. Easy casting of mass production, and the forging process was more complex, so the production cost is relatively high, but the forging hub in the production process for aluminum block after continuous stamping, so after forming, its molecular structure will become very close, so can withstand high pressure, and at the same size of the same strength, forging hub lighter than casting wheel.
Further, because the forging wheel structure, can bear high stress, so in the design, it can design some of the more lively thin spokes, freedom of design is higher but relatively, the price is the hub forging casting wheel is much higher, which are basically used in focus control high-grade car. And those high-performance super running, there are no exceptions to the use of forged wheels
Production and processing in different ways, so the characteristics of the use is also quite different. A cast wheel is a process of casting molten aluminum into a sand mold, which is then formed by mechanical processing (deburring, trimming, appearance, polishing) until it is cooled.
