Our deep draw stamping processes ensure we deliver the precise parts you need in the most efficient way possible, and our testing gives you confidence that we ship quality parts.

Benefits of Deep Drawn Parts

Our deep drawn parts offer numerous advantages over traditionally machined, cast, or molded parts. We can reverse-engineer existing components, and can often combine multiple parts into a single stamped piece. Deep draw stamping can:

  • Reduce costs
  • Reduce waste
  • Lower assembly cost and time
  • Improve metal structure to produce stronger finished parts.

Trans-Matic Deep Draw Metal Stamping Process

Step 1: Determine Scope
Trans-Matic produces deep drawn metal stampings up to 12” long (200mm) and from 0.008” (.127mm) to 0.180” (4.5mm) thick.

Step 2: Cutting Blanks
All deep drawn components start as a flat disc of sheet metal, blanked from coiled stock. Trans-Matic improves material utilization by staggering our blanks to reduce web scrap and cut costs. The deep draw stamping process minimizes waste, meaning your parts are made with the minimum amount of material required and you aren’t wasting money on metal that gets tossed in the scrap bin.

Step 3: Starting Cup
After cutting the blank at the first die station, the blank is cupped around the nose of a punch and pressed into a die to form a cup. This first deep drawing operation increases the strength of the part through work hardening.

Step 4: Keep Drawing
Depending on your desired length-to-diameter ratio, Trans-Matic will design tooling with several draws to create the basic shape of the part. The forces produced in the metal stamping process naturally cause the shell wall to thin out, while the shell flange thickens at each stage. Our team designs tooling to stretch the metal as evenly as possible into the part’s intended shape.

Step 5: Custom Features
Trans-Matic produces highly customized deep drawn parts for our customers. We utilize in-die stations to manufacture a variety of features:

  • Bottom piercing
  • Multiple side piercing
  • Extruding
  • Embossing
  • Marking
  • Burnishing
  • Ironing
  • Chamfering
  • Flange forming
  • Shaped flange trimming
  • Beading
  • Reverse drawing
  • Rib forming
  • Coining


Step 6: Not Just Thorough

Trans-Matic averages two imperfections per million. For us, excellence means working each day to lower that fraction just a little bit.
