Sheet metal spinning, also known as metal spinning, is a metal forming technique where a disc of sheet metal is rotated at high speeds and pressed onto an axially-symmetric mandrel in the shape of the end part. The resulting metal shapes are typically less complex and can be created using manual or CNC spinning equipment. These spun metal shapes find applications in decorative, architectural, and furniture industries, as well as in aerospace for making nose cones for rockets and planes. However, it is important to note that metal spinning is not suitable for creating asymmetrical designs. While metal spinning offers minimal tooling costs, the variable cost per-part is higher compared to hydroforming.

Deep drawing, on the other hand, is a cold forming metalworking process that involves forcing a punch through a series of forming dies to create a deep, seamless shape with minimal material loss. This process is best suited for producing simplistic, axially-symmetrical parts and is commonly used in the manufacturing of pressure vessels and tanks that require seamless construction to avoid potential points of failure.
