Metal Spinning

Metal spinning, also called as spin forming, spinning or spun metal manufacturing, is a metalworking process that forms sheet metal into a cylindrical or circular shape by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. The blank sheet metal is rotated about an axis while a form tool is pressed against the part into a chuck shape tool to form a desired shape. Spinning can be performed by hand or by a CNC lathe.

Metal spinning typically require low cost tooling when compared with similar processes, such as, drawing and punching manufacturing. Spinning tools are simple and easy to set up. Small production numbers are practical with metal spinning manufacturing. Labor costs tends to be higher, however these cost are easy to justify with low volume manufacturing vs. the high tooling costing of other processes. Material which may be used in spinning manufacturing including: Aluminum, Brass, Copper, Steel-cold rolled, Steel-hot rolled, Inconel and stainless steel.

Metal spinning ranges from an artisan's specialty to the most advantageous way to form round metal parts for commercial applications. Artisans use the process to produce architectural detail, specialty lighting, decorative household goods and urns. Commercial applications include rocket nose cones, cookware, gas cylinders, brass instrument bells, and public waste receptacles. Virtually any ductile metal may be formed, from aluminum or stainless steel, to high-strength, high-temperature alloys. The diameter and depth of formed parts are limited only by the size of the equipment available.
