What is deep drawing in manufacturing?

The term "deep drawing" specifically refers to the depth of the created item, which is equal to or greater than its diameter. The deep drawing process involves a single metal blank and forming it into a 3D circle, square, or rectangle, called a shell or shell.

Deep drawing is a sheet metal forming process in which the sheet metal blank is drawn radially into a forming die under the mechanical action of a punch. When the depth of the drawn part exceeds its diameter, the process is considered a "deep" drawing. This is achieved by redrawing the parts through a series of molds.
