The Flow Formed Process
Utilizing the latest forge-hybrid, flow-forming technology, Giovanna FF (Flow Form) wheels are 20-30% stronger and lighter than other cast wheels. The Flow Form manufacturing process maintains the integrity of the design, while improving the grain structure of the aluminum, creating a stronger, lighter and thinner barrel. The superb squeeze forging capability stretches the inner or outer portion of the wheel, resulting in a wider range of widths.
The cast preform is loaded onto a heated drum that will determine the final width of the wheel.
Rollers stretch and compress the barrel, widening and thinning it as they go.
The final wheel, lighter and stronger, is cooled and prepped for finishing.
