What is deep draw metal stamping?

Deep draw metal stamping is used to make cylindrical components from sheet metal, and can do so quickly, making it a high yield, but relatively low cost, way to make cylindrical parts. Deep draw metal stamping can make both simple and complex parts for several industries.

Deep draw metal stamping is a highly specialized type of sheet metal forming process whereby the sheet material is “drawn” into a die by a punch, forming the final shape of a product. Deep drawing is similar to stamping as both techniques use sheet metal to form into parts. The most significant difference between deep drawing and stamping is the tooling used. It is considered “deep” drawing when the forming tool is deeper than it is wide. Stamping relies on the cutting of the sheet metal whereas deep drawing actually deforms the material. The deep drawing process involves clamping the material as it is deformed to ensure the piece doesn’t move and to ensure the uniformity ...
... of the pieces being produced. Tooling is normally made from tool steel, although carbon steel is sometimes used when the application is not as demanding. Deep drawing presses are rare and expensive, and the knowledge needed to successfully produce products with them is high.

What techniques are used by deep draw stamping companies?

Sheet metal forming can pose challenges, as not every metal can be deep drawn. The N value of a material is its capacity to stretch, and the R value of a material is its capacity to form.

Deep draw metal stamping suppliers use techniques that involve a multitude of methods to form materials within the press. These methods include:

Beading
Bottom piercing
Bulging
Coining
Curling
Extruding
Ironing
Necking
Notching
Rib forming
Side piercing
Stamping
Threading
Trimming

How should I vet a deep draw stamping supplier?

When seeking out deep draw stamping companies for your next project it is important to remember several factors to ensure the success of your project.

First, the deep draw metal stamping process involves specialized machinery to create parts. It is important, then, that the company you seek out has a reliability or redundancy program for their equipment. For your project to be cost efficient, it must be completed in time without a pause in production. Pauses in production can come from equipment failure and the lack of resources to continue operating with a main line down.

Second, it is essential that the company understands your product and has the knowledge on how best to produce it in bulk. It is important to ensure that they have the knowledge needed to complete your project—and subsequent projects—on time and with the quality demanded.

Third, the company should have a track record of success, with several decades in the business and references to back up their experience. You can rest assured that a company with a long history of successful projects will also be an excellent choice for your next run.
