Forged Wheel Spacers or Casting Wheel Spacers?
The main manufacturing processes of wheel spacers on the market are forging and casting. Even with the same material, wheel spacers behave with different mechanical performances by different processes. Forged aluminum alloy wheel spacers are manufactured from a solid piece of billets. They have undergone continuous intense pressure to be formed. Particularly, forged wheel spacers are one-piece wheel spacers. Due to the continuous stress cycle and process of deformation, the forged wheel spacers become hard and tough. The strength is greatly enhanced.
Casting wheel spacers are considered to be inexpensive in terms of manufacturing. However, the major defect can’t be avoided- the nature of its manufacturing results in the occurrence of porosity. In addition, since it is not manufactured with the same structural integrity continuously, its mechanical properties are not as good as forging.
