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.

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.” deep drawn stamping uk

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. The problem was a client in Coventry: Apex

The challenge was immense. Unlike standard stamping, which cuts and forms shallow shapes, deep drawing forces a flat sheet of metal (a blank) into a die cavity using a punch. The metal flows like a slow-motion waterfall, stretching without tearing. For the battery housing, they needed to draw a 3mm-thick sheet of aerospace-grade aluminium 6061 into a 300mm deep box with radiused corners. Apex had tried fabricating the housings by welding
