Sheet metal spinning, also known as metal spinning or spin forming, is a metalworking process by which a flat metal disc or tube is rotated at high speed and formed into an axially symmetric part, such as a bowl, using a combination of rotational force and pressure applied via specialized tools. This technique, rooted in ancient craftsmanship yet refined through modern engineering, allows for the creation of seamless, durable, and aesthetically pleasing sheet metal bowls with applications ranging from industrial components to decorative household items. The process is distinct from other forming methods, such as deep drawing or stamping, due to its reliance on incremental deformation and its ability to produce complex geometries with minimal tooling costs.
