Deep Drawn Metal Stamping Uk -

British toolrooms are closing at an alarming rate (down 40% since 2010). Consequently, lead times for new progressive dies are now 16-24 weeks —double what they were pre-Brexit. You will wait 6 months for a £35k tool, only to find that the same tool from Portugal or Poland costs £22k and arrives in 10 weeks. For complex draws, the UK is still better; for standard draws, look to the EU.

Get your tools harden-cut in the UK, but consider having high-volume production runs done in Portugal or Czechia, then do final EDM or finishing back in the UK. Splitting the supply chain is now the only way to get both quality and cost. deep drawn metal stamping uk

While dimensional accuracy is high, secondary operations (deburring, passivation, vibratory finishing) are surprisingly weak. UK deep drawers assume you have your own finishing line. I have received "finished" parts with visible draw lines and micro-scratches that would never pass consumer electronics standards. Always specify Ra values in your RFQ, or you will be disappointed. The Ugly: What nobody tells you The "Forgotten" Corrosion Risk Many UK stampers use cheap chlorinated drawing lubricants to achieve deep draws on carbon steel. If the post-draw washing line isn't perfectly maintained (and in small shops, it often isn't), you get hydrogen embrittlement or flash rust 3 months later. Always request a residual oil analysis before shipping.
