Quality assurance
Quality
Uncompromising standards in every abrasive — backed by ISO 9001:2015 certification and a five-stage quality control framework.
Quality management system
Built on ISO 9001:2015
Every gram we ship is traceable
Our quality management system governs every stage from raw material intake to final shipment. Documented protocols, digital test certificates, and mandatory lot-by-lot testing mean there are no shortcuts and no exceptions.
Lab results are archived for 7 years. Each shipment carries a QR-linked test certificate — scannable by the end customer at any point in the supply chain.
In-house lab
Six tests on every batch
Our metallurgical lab conducts all mandatory tests in-house — no dependence on third parties, 4-hour turnaround, same-day release for urgent orders.
Hardness testing
10 sample particles per lot tested on a calibrated Rockwell tester. Target hardness must be within ±2 HRC of specification before any batch is approved for dispatch.
Sieve analysis
Ro-Tap vibratory sieve shaker verifies size distribution across full range S70–S930 and G10–G80. Out-of-range fractions trigger full reprocessing.
Chemical analysis
Optical emission spectrometer checks carbon, manganese, silicon, sulfur and phosphorus on every melt and again on finished product samples.
Microstructure analysis
Sections at 100–500× magnification confirm martensite content and absence of untempered martensite, retained austenite or inclusions.
Impact testing
Toughness evaluation for specialty grades. Validates that abrasives withstand repeated high-velocity impact without premature fracture or spalling.
Particle shape analysis
Sphericity and defect checks on shot product. Angular grit evaluated for facet sharpness. Out-of-round or hollow particles are screened out at this stage.
