Cast Aluminium The simplest type of casting is called Gravity casting and is done by pouring molten aluminum into a mold and letting it spread, harden and set. Low pressure casting is a slightly better process, whereby the aluminum is forced into the mold and set with vacuum pressure, where helps to eliminate those air pockets and increase structural integrity. While cast wheels can be quite strong, they are also heavy, making them not optimal for performance. Flow-Forming “Flow-forming” (also known as “roll-forging” and “spun-rim manufacturing”) starts out similarly to low pressure casting. But instead of letting the allow fully set, it is finished...
