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.
The story of Bromford Precision is not unique. Across the UK—from the precision engineering clusters of Sheffield to the aerospace hubs of Bristol— has become a quiet champion of reindustrialisation. It is the unsung hero that turns a flat disc of steel into a gas canister, a coil of brass into a cartridge case, or a sheet of Inconel into a jet engine combustion chamber liner.
They rebuilt the process from scratch. They introduced a multi-stage drawing cycle: first a shallow pre-draw, then an intermediate redraw, then a final ironing stage to thin and smooth the walls. They replaced standard mineral oil with a high-viscosity chlorinated extreme-pressure lubricant. They even adjusted the blank holder force dynamically using sensors—too little, and the metal wrinkled; too much, and it ruptured.
Apex EV was ecstatic. The deep drawn housing passed the UN’s ECE R100 crash test with 15% more impact resistance than the welded version, while being 22% lighter. Within six months, Bromford Precision wasn't just making battery housings. They were drawing fuel tank bodies for hydrogen lorries, medical canisters for surgical implants, and electromagnetic shielding enclosures for defence radar systems.
That process is called .
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.
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.
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.
