Want to know the difference between gravity cast vs flow form? Gravity casting wheels process: Gravity casting is the most basic and traditional method of wheel manufacturing.This is the most primitive processing method for aluminum alloy wheels, which can be formed by pouring high-temperature liquid metal into the mold and cooling it. This method is efficient and low cost, but the uniformity of each part of the manufactured casting wheel is poor, and the molecular density is relatively low, resulting in low strength, so it is not very suitable for high-strength use of passenger vehicles. Despite their drawbacks, gravity cast wheels offer a decent level of strength and a variety of styling options.
