From incoming raw material to final shipment, every casting passes through our in-house metrology lab β equipped with OES spectrometer, industrial X-ray NDT, universal testing machine, CMM, and hardness testers. ISO 9001 certified.
Driven by Managing Director Mr. Nathan Gan's uncompromising standards, our quality system ensures the prototype you approve is exactly what you receive in full-scale mass production.
Every heat of metal is spectrographically verified before casting. We test chemical composition, mechanical strength, and hardness β ensuring alloy compliance from ingot to finished part.
Our dust-free, temperature-controlled metrology lab houses a CNC CMM and vision measuring system, delivering full 3D geometric verification against approved drawings and tolerances.
Every batch is documented β from FAI reports and CPK data to material certifications. A complete paper trail connects first article approval to every production shipment.
Our QA team executes a rigorous verification sequence across every project β from raw material intake through final shipment documentation.
OES spectrographic analysis of raw ingots verifies exact chemical composition before any casting begins.
Real-time hardness and dimensional checks during casting and CNC machining phases catch deviations early.
Non-destructive X-ray detects internal porosity, shrinkage, cold shuts, and inclusions invisible to the eye.
CNC CMM delivers comprehensive 3D geometric verification against approved drawings. VMS covers micro-features.
FAI reports, CPK data, and material certifications generated and archived for every project and shipment batch.
X-Ray Inspection Room β Unicomp UNC225B202 | Renyi Castings QA Lab, Ningbo
Our Chongqing Unicomp UNC225B202 (UNC225 Series) industrial X-ray system allows us to non-destructively examine the internal structure of finished castings β without cutting, sectioning, or any damage to the part.
Internal defects that are completely invisible on the surface β porosity clusters, shrinkage cavities, cold shuts, foreign inclusions, and subsurface cracks β are clearly revealed and documented before shipment.
Every incoming ingot is verified against the specified alloy grade before it enters production. The Hitachi FMS delivers spark OES analysis in seconds β certifying elemental content with foundry-grade precision.

Measurement accuracy depends on environmental stability. Our dedicated metrology lab maintains strict controls on temperature, humidity, and particulate β protecting every sensitive instrument inside.
Our lab maintains a temperature variance of only Β±0.1Β°C, ensuring high precision in all measurements.
The laboratory constantly maintains an appropriate humidity level through instruments such as humidifiers.
Protecting sensitive optical sensors and air-bearing surfaces.
We generate and archive a full set of quality documentation for every project β giving you the evidence you need for your own supplier qualification process.
Full dimensional and material verification report for the first production article before mass run begins.
Statistical process capability data demonstrating consistent output within defined tolerance bands.
OES spectrometer output certifying the exact chemical composition of the alloy used in your order.
Pre-shipment dimensional and visual inspection report for each batch, archived per shipment lot.
