Metal Stamping - Deep Drawn Stamping

Time to Read: 3m 12s

Metal stamping is the process of forming sheet metal with a punch or with a machine press. Metal stamping is also known as deep drawn metal stamping, deep draw stamping, and progressive die stamping. In a metal stamping operation a punch and die is used. The punch is the male part and the female part is the die. The component that activates the punch is called the metal stamping press machine.

The Metal Stamping Process

This deep drawing process video shows the metal stamping process, in which a roll of flat sheet metal enters the press, and in progressively stamped into a completed component.

Deep Drawn Stamped Metal Parts

The simplest kind of deep drawn metal stamped part is a basic cylinder, in which a round piece of sheet metal has been progressively punched by a die into a cylindrical shape. However, modern metal stamping is capable of producing a myriad of shapes, including rectangular and asymmetrical shapes, and shapes with holes, sockets, and even threaded parts. Metal stamping involves a more costly set-up than machined parts, but makes up for that cost in efficiencies in volume. Because of this deep drawn metal stamping is commonly used only for production of very large quantities. Metal stamping is also capable of combining multiple traditionally machined parts into a single deep drawn metal stamping. In these cases the final part has greater strength, and sees additional cost savings by eliminating the expense of assembly of the multiple components. Just about everyone in the world comes into contact with deep drawn metal stamped parts every day. Some of the applications of the metal stamping process include aerosol cans, water bottles, military tanks, automotive parts, oxygen sensors, plumbing parts, audio and video parts, and much more.

Metals Used in Deep Drawn Stamping

The metal stamping process can use many different kinds of metals, including ferrous and non ferrous metal. Just some of the materials that can be used in metal stamping include:
  • Steel (carbon steel, alloy steel, and stainless steels)
  • Aluminum
  • Copper
  • Brass
  • Bronze
  • Gold
  • Silver
  • Beryllium Copper
This metalwork process can be as precise as necessary, and precision metal stampings are. Many metal types can be used in metal stamping such as ferrous and non ferrous metal, gold and silver and even exotic metals like beryllium copper. One if the important areas to stress with regard to deep drawn metal types is that every metal has different characteristics that offer different benefits to parts but also have different challenges in a metal stamping context. It is simply not as easy to deep draw stainless steel as it is low carbon steel, particularly when trying to achieve variable wall thickness. Just because a deep draw stamping manufacturer is capable and experienced with one metal type does not necessarily mean that they can produce quality deep drawn parts of a different metal type.
