The first week was a disaster. The blanks tore at the corners, leaving jagged scars. The second week, they solved the tearing but introduced earing —wavy ripples at the top edge caused by the metal’s grain structure fighting back.
And she smiles, because the deepest draws are no longer a problem. They are the future. Key takeaway: Deep drawn stamping in the UK is vital for industries like automotive (EV batteries), aerospace, medical devices, and defence, offering seamless, high-strength, lightweight components where traditional fabrication fails.
That process is called .
The problem was a client in Coventry: Apex EV , a startup building the next generation of electric vehicle battery housings. These weren’t simple trays. They were complex, monolithic enclosures requiring near-micron precision—deep, seamless cavities that could protect volatile lithium cells from crash impacts and thermal runaway. Apex had tried fabricating the housings by welding multiple stamped pieces together, but the welds were weak points. They needed a single piece of metal, transformed into a shape deeper than its own diameter.
In the heart of the West Midlands, where the black country’s industrial hum had faded to a whisper, a family business named Bromford Precision was fighting for its life. For three generations, they had stamped simple brackets and washers for the automotive industry. But by 2024, the margins had shrunk to vapour. The owner, Eleanor Bromford, stood on the shop floor, watching a press clunk out a simple cup-shaped component. She knew that if her company was to survive, it had to shrink the metal, not the ambition. deep drawn stamping uk
On the 43rd night, at 2:17 AM, the press cycled. The blank was fed, the punch descended, and the metal flowed. The press opened. A single, flawless battery housing emerged—mirror-smooth inside, uniform wall thickness of 1.8mm, with integrated mounting bosses formed in the same stroke. No welds. No leaks. Just strength.
Today, when Eleanor walks the floor, she doesn’t hear a clunk. She hears a symphony. The rapid thump-thump-thump of the transfer press is the heartbeat of a nation rediscovering its ability to make complex, durable things from raw metal—one deep, perfect draw at a time. The first week was a disaster
Eleanor called in a consultant from the University of Sheffield’s Advanced Manufacturing Research Centre (AMRC). The diagnosis was brutal: “You’re treating it like a press shop. You need to think like a metallurgist.”
