Flow Forming is a metal forming technique in which a disk or tube of metal is formed over a mandrel by a roller using tremendous pressure. The roller shears the metal, forcing it against the mandrel, creating the shape and width of the final product.[1] Flow forming subjects the workpiece to a great deal of friction and can heat the workpiece to several hundred degrees.
Flow forming is often used to manufacture automobile wheels and can be used to draw a wheel to net width from a machined blank. [2]
During flow forming, the workpiece is cold worked, changing its mechanical properties, so its strength becomes similar to that of forged metal.
