Nearly perfect is not an option.

Trans-Matic serves a broad array of industries—including automotive, plumbing, lock hardware, lawn equipment, and builders’ hardware—with expertise in many different grades of metal. Our processes ensure we design the precise part you need in the most efficient way possible, and our testing gives you confidence that we ship quality 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, and improve metal structure to produce stronger finished parts.

  1. Determine scope.
    Trans-Matic draws parts up to 8” long (200mm) and 0.008” (.127mm) to 0.180” (4.5mm) thick.
  2. Cutting a blank.
    Every part starts with a flat disc of sheet metal, blanked from coiled stock. Trans-Matic improves material utilization by staggering the blanks to cut the maximum number from each coil of sheet metal we use. Deep drawing minimizes waste, meaning your parts are made with the minimum amount of material required and you aren’t wasting money on metal that get tossed in the scrap bin.
  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 drawing operation increases the strength of the part through work hardening.
  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 tension of the deep drawing process naturally causes the shell wall of a part to thin and the shell flange to thicken at each stage. Our team designs tooling to stretch the metal as evenly as possible into the part’s intended shape.
  5. The pressure is on.
    As the part moves on to remaining stations, tension in the metal wall causes the part to stretch while compression in the shell flange can cause it to thicken slightly. The metal strengthens and grows more rigid with every stage of the drawing process.
  6. Custom features.
    Trans-Matic produces both standard and highly customized parts for our customers, utilizing in-die stations to create:

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

     

  7. 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.
