A part is considered "deep drawn" when its depth is equal to or greater than its diameter.
Deep drawing is the only process that can produce a 0.2mm thick aluminium can with perfectly flat, burr-free edges. Midlands-based press shops are currently running 24/7 to supply these to gigafactories—proving that British cold-forming is world-class. Deep drawing isn't easy. If you push too fast, the metal tears. If the radius is too tight, the metal wrinkles. deep drawn pressing uk
With energy prices volatile across the UK, melting scrap down is expensive. Deep drawing produces almost zero waste. You start with a perfect circle of metal; you end with a perfect cup. There are no chips on the floor, no re-melting costs, and no secondary waste disposal fees. A part is considered "deep drawn" when its
Think of a stainless steel sink, a brass hose fitting, or the casing for a UK-made military flare. These aren't welded or glued; they are one continuous piece of metal, stretched into existence. Why are British aerospace, medical, and defence contractors sticking with deep drawing over 3D printing or casting? Deep drawing isn't easy

When you machine a part from a solid block, you cut through the metal's natural grain lines, weakening the structure. Deep drawing flows with the grain. The result is a part that is significantly stronger and more resistant to fatigue than a machined or welded alternative.
For hydraulic components, gas canisters, or EV battery enclosures, a seam is a liability. Deep drawn parts have no welded bottom seam. They are monolithic—literally impossible to leak through the sides or base. Case Study: The Electric Vehicle Revolution The UK’s push toward Net Zero is a massive opportunity for deep drawing. EV batteries require thousands of precise, cylindrical or prismatic cans. These cans need to be thin (to save weight) and strong (to contain thermal runaway).
