What is Flow Forming?
Flow Forming Technology involves the application of pressure to the inner barrel of the wheel, while spinning & after it has been casted. This process shares similarities to that found in the forging process in which the aluminum molecules are compressed resulting in a lighter & stronger wheel with greater shock resistance & elongation properties.
