Deep Draw Metal Stamping


Stronger and smarter component solutions for your business.

With extensive experience working with many different types and grades of metal, Trans-Matic serves a broad array of industries, including automotive, plumbing, lock and builders’ hardware, lawn equipment, and more. Each deep draw process we use ensures we deliver the precise parts you need in the most efficient way possible, and our testing gives you confidence that we ship quality deep draw parts.

Trans-Matic’s Deep Draw Stamping Process

Deep-drawn metal stamping is a technique that uses metal dies to form metal sheets into specified design shapes. Unlike standard metal stamping, deep-drawing creates deep stampings with a depth measuring at least half of their diameter. As a cold-forming process, deep drawing alters the metal at room temperature, which results in more robust, more durable components. 

The deep-drawing process makes various products ranging from kitchen sinks and fire extinguishers to baking pans, solenoids, assembly housings, and aluminum cans. These deep-drawn objects may be functional, decorative, or both, depending upon the application. 

Metal drawing provides a cost-effective solution for automotive, hardware, HVAC, plumbing, and numerous other industries.

01 Determine Scope

Trans-Matic produces deep drawn parts up to 9.5” long (240mm), using materials from 0.004” (0.100mm) to 0.180” (4.5mm) thick.

02 Cutting Blanks

Every deep-draw stamping starts as a flat disc of sheet metal, blanked from coiled stock. Trans-Matic improves material utilization by staggering our blanks to reduce scrap and material costs. The deep-draw transfer stamping process minimizes waste, meaning your parts are made with the minimum amount of material required and you aren’t spending money on metal that ends up in the scrap bin.

03 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-draw forming operation increases the strength of the part through work hardening.

04 Keep Drawing

Depending on your desired length-to-diameter ratio, Trans-Matic will design tooling with several draws to create the basic shape of your deep-draw parts. The forces produced in the deep-drawn 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.

05 Custom Features

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

  • Marking
  • Bottom piercing
  • Multiple side piercing
  • Reverse drawing
  • Rib forming
  • Shaped flange trimming

06 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.

Deep Drawing Process Used for Different Industry Applications

Numerous industries rely on deep-drawn parts, including:
  • To resist corrosion and high heat or high pressure, Appliances use deep-drawn precision nozzles, housings for sensors, and various thermostatic components made from 300-series stainless steel that withstand high temperatures, high pressures, and corrosion.
  • Automotive. Vehicles experience harsh conditions, such as vibrations, temperature extremes, and impacts. Components used in vehicles require durability to facilitate reliable operation. For this industry, durable, seamless deep-drawn parts include exhaust mufflers, leak-proof fluid containers, jounce bumpers, body mounts, engine mounts, and pins and connectors.
  • Hydraulic and pneumatic valves. Valves containing deep-drawn components see broad usage across industries. These valves are often made with copper or stainless steel — sometimes with special coatings, depending upon the application.
  • Medical. The medical sector relies on deep-drawn stamping for large production runs of syringes, insulin delivery devices, pacemakers, surgical devices, and temperature-sensing probe covers using stainless steel, titanium, and more.
