Flow forming

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. [ [http://www.pmfind.com/flowforming.asp Flow Forming - Stainless Steels and High-temperature Alloys - PMF Industries, Inc ] ] 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. [http://www.bbs-usa.com/index.php?id=330]

During flow forming, the workpiece is cold worked, changing its mechanical properties, so its strength becomes similar to that of forged metal.
