When your customer audits your supply chain, the question is never whether the part measures correctly — it is whether you can prove where the material came from. Certificates are that proof, and we treat them as part of the product.
Material certificates available with your parts, tied to the batch and the drawing revision.
Certificate chemistry is cross-checked on our spectrometer, so the paper matches the metal.
Certificates, dimensional reports and traceability records form one consistent documentation set.
Real capability windows — verified in-house, not estimated.
