Spin-formed wheels maintain the density of the metal and the dynamic balance of the entire wheel, making the wheel lighter and more durable by significantly reducing the thickness of the material while providing sufficient stiffness.
Flow forming is one of the most advanced manufacturing technologies to enter the wheel industry. Flow Forming Technology involves the application of pressure to the inner barrel of the wheel, while spinning and after it has been casted. This process stretches and compresses the aluminum, which increases tensile strength. In this respect the process shares similar properties to those found in the forging process. The final product is lighter, stronger, has increased elongation, and a much greater shock resistance as well as an increased load capacity over regular cast wheels.
