Deep Draw Stamping: The Art and Science Behind Trans-Matic’s Legacy

Deep draw stamping is a metal forming process that transforms flat sheet metal into three-dimensional shapes, typically with a high depth-to-diameter ratio. A flat metal blank is placed over a series of dies and then forced into the die cavities with punches. This results in intricate shapes with smooth surfaces and precise dimensions.

Since its inception in 1968, Trans-Matic has been at the forefront of deep draw stamping, perfecting this technique and becoming a leader in the industry. In this article, we will delve into the fundamentals of deep draw stamping, its contemporary applications, and Trans-Matic’s innovative approach!

Fundamentals of Deep Draw Stamping

The fundamentals of deep draw stamping revolve around several key principles and processes, including:

Blank Preparation

The process begins with a wound coil of strip steel, which is fed into a press and cut to the appropriate size and shape for the desired component. The blank’s dimensions are crucial as they directly influence the final part’s characteristics.

Die and Punch Design

The die cavity defines the part’s final shape, while the punch applies force to draw the blank into the cavity. Both components must be carefully designed to ensure proper material flow, minimize wrinkling, and achieve the desired dimensions and surface finish.


Lubricants are applied to the blank and tooling surfaces to reduce friction and prevent galling during stamping. It helps maintain material flow, reduces wear on the tooling, and improves the quality of the finished parts.


The blank is securely clamped between the die and punch during the drawing process. The punch applies force to draw the blank into the die cavity, causing it to deform and take on the shape of the hole. The material undergoes both radial and axial deformation, with the depth of the draw determined by the ratio of the blank’s diameter to its height.

Trimming and Finishing

The flash or excess material is typically trimmed away from the part after the drawing process is complete. Additional secondary operations — including piercing, punching, or machining — may be performed to achieve the final part’s desired features and tolerances. Surface finishing processes may also be applied to improve the part’s appearance and functionality. These include deburring, cleaning, and coating.

Key Applications in Modern Manufacturing

In modern manufacturing, deep draw stamping plays a crucial role across various industries due to its numerous benefits. This technique’s applications include the following:

  • Automotive (e.g., exhaust system components, fuel assemblies, oil and powertrain parts, sensors, braking and safety critical parts)
  • Electronics (e.g., enclosures, housings, connectors, solenoids, and circuitry)
  • Medical devices (e.g., surgical instruments, diagnostic equipment, and medical device enclosures)
  • Consumer goods (e.g., kitchen appliances, cookware, household fixtures, and consumer electronics)
  • Power generation (e.g., heat exchangers, turbine blades, and fuel cell plates)
  • HVAC (e.g., plumbing, gas and water lines)
