Flow Formed Wheels: Definition & Manufacturing Process

Flow Formed wheels are also commonly referred to as Spun Forged, Flow Forged, Rotary Formed, or Rotary Forged. While manufacturers may use different terminology, these names generally describe the same wheel-forming process. These wheels start as a cast wheel that's placed into a machine that spins it quickly, while steel rollers apply pressure to stretch the barrel downward to its final size and specifications. This process stretches and compresses the aluminum, which increases tensile strength.

It’s important to understand that this manufacturing process is different from a true forged monoblock wheel.
