Step 4 of the forging process: Flow-forming the barrel. The name can be confusing, as it’s also used to describe cast wheels that go through this process as an extra step. The flow-forming process can be used on both cast and forged wheels to shape the barrel. In this step, the thick, unformed barrel portion of a forged wheel blank is drawn down over a drum under intense pressure, which stretches it out to its final width and profile. This step creates a dense barrel with the metal’s grain struc

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. | YHI Singapore | Facebook
