Ceramic quality control has one honest definition: measured proof that the parts in the box match the drawing that ordered them. FineCer's ISO 9001:2015 quality system delivers that proof on every shipment — CMM dimensional data, density, hardness, surface roughness, and 100% visual inspection, reported as actual values rather than pass/fail ticks — backed by batch traceability that links finished parts to their powder lots and process records. For buyers qualifying an overseas ceramic supplier, this page is the audit preview: what we measure, with what, and what lands in your inbox.
Inspection Equipment
| Equipment | Function | Capability |
|---|---|---|
| CMM | 3D dimensional | ±0.001mm |
| 2.5D Optical | Profile/contour | Non-contact |
| Surface Roughness Tester | Ra/Rz verification | 0.001μm resolution |
| Density Meter | Material density | Archimedes method |
| Hardness Tester | Vickers hardness | HV 0.1–50 kgf |
| Roundness Tester | Form accuracy | ±0.0001mm |
What We Test
- Dimensional accuracy vs drawing specs
- Surface roughness at multiple points
- Density (Archimedes method, >99% theoretical)
- Hardness (Vickers indentation)
- 100% visual inspection for defects
- Form accuracy (roundness, parallelism, concentricity)
Quality Starts Before the Furnace
A finished-part inspection can only reject problems; preventing them happens upstream. Incoming ceramic powders are verified against their material certificates before release to production, because powder chemistry and particle characteristics set the ceiling on everything downstream — no grinding operation rescues a bad sinter. In-process gates then track each batch through the chain: formed blanks checked before the furnace, sintered density verified against the >99%-of-theoretical standard before any diamond time is spent, and machined dimensions confirmed at the machine before parts move to final inspection. Catching a deviation at the stage that caused it is the difference between a same-day correction and a scrapped batch — and it is why our quality complaint rate stays below 0.5%.
Why Density Is the Ceramic Truth-Teller
Of everything on the test list, density is the most diagnostic single number for a ceramic part: porosity left behind by incomplete sintering silently cuts strength, wear life, and chemical resistance even when dimensions measure perfectly. The Archimedes verification on every batch is therefore not a formality — it is the check that the material inside the part matches the datasheet that justified choosing it. Hardness testing plays the same confirming role for wear parts, and form accuracy (roundness to ±0.0001mm resolution) underwrites every sealing and rotating application on this site.
Every Shipment Includes
- Dimensional inspection report
- Material certificate
- Surface roughness data
- Visual inspection record
- Batch traceability number
That documentation set ships by default — sample order or production batch alike — so your incoming inspection can confirm rather than re-measure, and a re-order two years later traces to the same standards. Where regulated industries need more, enhanced packages are assembled per requirement, coordinated by the same dedicated engineer who runs your project under our project management process.
