What is Spin Forged?
IT’S ALL ABOUT INNOVATION
Rotary Forged or Spin Forged is the technology of Flow Forming a wheel and is one of the most innovative manufacturing processes to enter the wheel industry. This complex process involves the application of heat and pressure to the inner barrel of the wheel, stretching and compressing the aluminum, which increases the tensile strength of the barrel. This development shares similar properties to those found in the forging method.
The final product is lighter, stronger and has improved shock resistance as well as an increased load capacity over regular cast wheels. The major difference between cast and flow-formed wheels is in the thickness of the wheel barrel. The flow forming process increases the strength of the aluminum allowing the barrel to be made much thinner and lighter than a regular cast wheel.
A specially designed aluminum cast is created with the barrel ready to be Flow Formed.
The wheel now spins at a high rate as it gets heated to allow for the stretching of the material.
Once heated, the rollers press onto the barrel in a downward motion to the required width of the wheel.
As this process finishes, the aluminum strengthens giving the wheel higher impact tolerance.
