Flow Forming

Flow Forming is a metal production procedure that turns the metal over a special mandrel and hydraulic rollers using tremendous pressure. The pressure and turning then force the metal area to form against the mandrel, creating the shape and width of the final product.[1] During Flow Forming in automobile wheel production, the rim actually "flows” down to create the full rim width. [2]

During Flow Forming, pressure applied to the cast metal actually changes its mechanical properties, so its strength and impact values become similar to those of a forged metal. That translates to up to 15% less weight when compared to a standard cast metal.
