Deep drawing
Deep drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. It is thus a shape transformation process with material retention.

Characteristics of deep drawing
Deep drawing stamping offers many advantages over other metal forming processes. Punch presses are designed to operate at high speed and can be equipped with automatic feeders for increased efficiency. In fact, deep drawn stamping is one of the quickest manufacturing methods for high-volume production.Deep drawn components are also created in one piece, thereby reducing the need for additional assembly. This has the added benefit of seamless construction, which is ideal for waterproof or airtight applications.
Deep drawing stamping is highly versatile and can be used to create complex, detailed components with an exceptional degree of accuracy and repeatability. What’s more, deep-drawn parts are exceptionally strong due to the extreme amount of compression exerted on the metal during the forming process. The basic structure of deep drawn metals is often highly compressed into a very hard crystalline structure.
