Rogue Engineering GTR Wheel Flow Forming Video

After the Rogue Engineering GTR casting has been done, some CNC machining is done to prep the wheel for the flow forming process. This process is also referred to as "flow forged" or "rotary forged".

After the preform is heated in the oven just the face is quenched to cool it down while the remainder of the wheel is still warm. During this process, the flow form tooling is heated.

The preform is loaded into the flow forming machine, it is secured and brought up to a designated speed where rollers are pressed against the sides to "form" the barrel. This not only changes the molecular structure of the rim barrel to be stronger, but also thinner. The rollers are pressed against the preform between 19 to 24 tons of pressure, depending on the requirements.

After the flow forming is completed, the entire rim is then quenched to cool off.

After this process, the rim will go to final CNC machining where the outside edges, inside face, outside face gets it's finishing work before painting.
