Industry Focus
Casting & Foundry
Grade-correct alloys. Defect-free microstructures. SG iron verified.
How QML Serves This Industry
Foundries and casting suppliers need fast, reliable material verification to release production batches and satisfy customer quality requirements. QML provides OES chemical analysis for melt and ladle samples, microstructural examination for nodularity and graphite morphology, and hardness verification for cast iron, aluminium, copper, and zinc-base castings.
Testing Scope for Casting & Foundry
Every testing requirement matched to what QML does and the applicable standard.
| Testing Requirement | What We Do | Standard |
|---|---|---|
| Melt / ladle chemical analysis | OES analysis of solid sample — elemental composition including C, Si, Mn, S, P, Mg, Cr, Ni, Cu | IS 8811 / ASTM E415 / JIS 1253 |
| Grade verification (grey iron / SG iron / alloy cast iron) | OES against IS 210, IS 1865, IS 14982 / ASTM A48, A536 grades | IS 8811 / JIS 1253 |
| Nodularity assessment of SG / ductile iron | Metallurgical microscopy — nodularity %, nodule count/mm², graphite form/distribution per ISO 945 | ISO 945 / ASTM A247 |
| Microstructure (pearlite %, ferrite %, carbide) | Etched section at 100×–500× — matrix phase identification and distribution | ISO 945 / Metallographic |
| Hardness of finished casting | Brinell HBW on machined surface — compare against specification | ASTM E10 / IS 1500 |
| Porosity / shrinkage evaluation | Cross-section metallography — area fraction and distribution of porosity | Area fraction method |
| Aluminium / copper / zinc alloy verification | OES for non-ferrous alloys — Al, Cu, Zn, Mg, Si, Fe, Ni, Mn content | ASTM E1251 / E478 |
