Deep Drawn Metal Stamping and Its Forming Techniques

Drawing liquids through different hoses, pipes and other devices requires the forming of metal connectors and couplings. These parts create a solid attachment between different materials while funneling the liquid to its destination.

Mass production techniques of these connectors and couplings rely on metal-forming methods that can produce high quality shapes in a fast amount of time while reducing the amount of wasted materials. One such method that is popular among manufacturers is deep drawn stamping. You can also get the information about hydraulic metal press from various online sources.

Deep Drawn Stamping Overview

Deep drawn stamping requires the use of metal dice that form regular and irregular metal shapes in sheet metal blanks. The term “deep drawn” refers to when the depth of the created metal shape is equal to or greater than its overall diameter. The metal blank is placed on a plug as it is moved and elongated across the die using constant pressure until the desired shape becomes stamped into the metal blank.

A big reason many manufacturers prefer the deep drawn process is that the single-created part is seamless and can replace parts that have multiple components. This method cuts down on time and money spent on subpart assembly and numerous metal forming operations to put together the overall part for use in commercial and residential applications. A wide range of different metals can be used in the deep drawn process:

  • Bronze
  • Brass
  • Aluminum
  • Iron
  • Nickel
  • Silver
  • Stainless steel
  • Cold-rolled steel
  • Copper
  • Tungsten

Forming Techniques for Deep Drawn Stamping

Deep drawn stamping usually involves other combined techniques to form the metal part as it moves through the press. The forming method you choose will be based on the type of metal part you are creating and its application.


Beading allows you to create a ring of material through the method of displacement as the ring diameter is larger or smaller the original diameter of the part.


This technique allows the creation of a rolled edge to the metal part.


A large diameter punch is pushed through a previously created pilot hole as it expands the metal and allows it to grow in length.
