WHATS THE DIFFERENCE BETWEEN WHEEL FORGING AND CASTING?
FORGING uses intense heat and pressure to transform a solid slug of alloy material into the final shape of a wheel. FORGED ALUMINIUM IS ABOUT 300 PER CENT STRONGER THAN CAST ALUMINIUM, yet less material is needed to produce the same “cast alloy wheel”, which results in a lighter product. Because of the basic limitations inherent in forging, most forged wheels are two or three piece units. In two-piece construction, a centre is forged and welded or bolted into a spun or stamped outer rim. In a three-piece wheel, the centre is bolted to an inner and an outer rim half. This stands as an advantage of being easily customisable for a variety of widths and offsets. CASTING is a relatively inexpensive way to produce a high-quality, fairly strong alloy wheel. There are two methods used. One, system is known as gravity casting whereby the molten material is poured into a mold and allowed to cool. These molds are usually made by machining a piece of material on CNC machine equipments to produce a
