Which sites do these certificates cover? The certificates above are held by Ningbo Empire Advanced Material Co., Ltd at the Ningbo site listed on each card. Manufacturing partners in our group operate under their own quality systems and certificates — for any specific part number or program, we confirm the producing site and its applicable certificate scope during quotation.
Our Quality Process
- ✓ Incoming material inspection — every raw material lot tested for composition and magnetic properties before production release.
- ✓ In-process controls — SPC monitoring of critical dimensions and magnetic properties at every process step.
- ✓ Final inspection — 100% visual and dimensional sampling per AQL, magnetic property testing per lot.
- ✓ CMM verification — coordinate measuring machine reports for complex geometries and tight tolerances.
- ✓ Full traceability — every shipment traceable to raw material lot, production date, and inspection records.
Documentation We Provide
