What happens after you send your files

  • Within 1 business day an engineer — not a salesperson — reviews your drawings and replies.
  • DFM review: tolerances, material and risk flags, before any cutting begins.
  • Your quote includes a material-verification plan: grade, EN/DIN check, certificate strategy.

Every critical dimension is verified on our in-house Zeiss CMM · material chemistry confirmed by spectrometer · EN 10204 3.1 certificates available.

Programs at 1,000+ pcs/year or recurring production are prioritized by our engineering team.
Built for qualified programs.
Our form captures production type, annual quantity and project status up front — so we can focus engineering resources on long-term supply relationships, not one-off inquiries.
