American Off Road Wheels is the first to introduce truck wheels produced using Rotary forged technology for both the barrel and lip, also known as Flow Forming. Once wheels centers have been cast, they are spun at a high rate of speed, while at the same time special circular rollers add extreme pressure to the inner barrel and outer lip creating a stronger, unmatched, compressed aluminum barrel and a massive stronger front lip. Over all American Off Road Wheels are stronger and lighter than almost any other truck wheel in the market today.
In flow-forming, a cylindrical preform is fitted over a mandrel. After both are made to rotate, compression forces are applied to the outside diameter of the preform by three CNC-controlled rollers. The desired geometry is achieved when the outer diameter and the wall of the preform are decreased and the available material volume is forced, through plastic deformation, to flow longitudinally over the mandrel. Typically, the preform can be flow-formed four to six times compared to its starting length before needing re-annealing.
The flow form process creates a more compressed and dense wheel that requires less material, boosting weight reduction.
Compressed and elongated, the make up of the material allows it to be more impact resistant than conventionally cast wheels.
When combined, the lighter and stiffer attributes of the wheel births a strong, high performance wheel.
