06 / Quality Control

Quality you can verify.

See the full process

Incoming material tested

Diamond grit, metal bond powder and steel substrate are sampled and logged against our incoming-inspection standard. A lot without a certificate, or outside tolerance, is rejected at the gate.

±3 %mesh tolerance · strength index ≥ 45

Sintering under log

Every furnace load keeps its ramp, soak and cooling curve on file, and a sampled segment is measured for HRB hardness and density before the lot moves on.

700–900 °Chot-press sintering window

Seventeen checkpoints

Twelve checkpoints sit inside production and five guard final release. Failing any one of them stops the lot — inspection is spread across the line, not saved for the end.
