Ask Balford is a free engineering Q&A for metalworking — deep drawing, fine blanking, progressive and transfer dies, materials, tolerances, DFM and RFQ preparation. It answers only from Balford's own published engineering pages and links the page under every claim. It refuses rather than guesses: ask for a tolerance, grade, price or lead time that isn't published and it says so. Ask about IATF 16949 and it tells you the controls are aligned but the certificate is not held.
