While global manufacturing has shifted towards cheaper labour markets, the UK has retained a stronghold in high-value, precision engineering. When searching for , manufacturers are often looking for specific high-end capabilities:
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.
If the desired depth isn't reached in one "hit," the part passes through successive dies to deepen and refine the shape.
Deep drawn stamping is a sheet metal forming process where a flat blank of sheet metal is radially drawn into a forming die by the mechanical action of a punch. Unlike standard stamping, which might involve shallow bends or cuts, deep drawing creates parts with a depth greater than their diameter.
Are you looking for a UK-based partner for your next metal forming project? Ensure your supplier has the tooling capability and quality accreditations to meet your engineering demands.
If you are looking for , consider the following when vetting a supplier:
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.
