    • 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.

    • The process of flow forming starts out with a precisely casted wheel that’s narrower then its final width.

    • The wheel is spun under heat while applying pressure to the inner wheel.

    • The end result has arrived to it’s desired width & is now stronger, lighter & shares properties of that of a forged wheel.
