From bullet casings to battery enclosures, deep drawn pressing offers unrivalled strength and precision. Discover how UK manufacturers are leveraging this cold-forming technique to outcompete global rivals. When most people imagine metal pressing, they picture a simple flat shape punched out of a sheet—like a coin or a washer. But what if you need a seamless cylinder, a complex dome, or a battery case thinner than a credit card?
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).
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.
