Our Quality Philosophy​

Three Pillars of Excellence

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.

⚗️
Material Integrity

Every heat of metal is spectrographically verified before casting. We test chemical composition, mechanical strength, and hardness — ensuring alloy compliance from ingot to finished part.

📐
Dimensional Precision

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.

📋
Process Traceability

Every batch is documented — from FAI reports and CPK data to material certifications. A complete paper trail connects first article approval to every production shipment.

QA Process

Comprehensive 5-Step Quality Workflow

Our QA team executes a rigorous verification sequence across every project — from raw material intake through final shipment documentation.

1
⚗️
Incoming Material

OES spectrographic analysis of raw ingots verifies exact chemical composition before any casting begins.

2
🔍
In-Process Sampling

Real-time hardness and dimensional checks during casting and CNC machining phases catch deviations early.

3
📡
X-Ray NDT Inspection

Non-destructive X-ray detects internal porosity, shrinkage, cold shuts, and inclusions invisible to the eye.

4
📏
CMM Full-Dimensional

CNC CMM delivers comprehensive 3D geometric verification against approved drawings. VMS covers micro-features.

5
📄
Documentation & FAI

FAI reports, CPK data, and material certifications generated and archived for every project and shipment batch.

Non-Destructive Testing

Industrial X-Ray — See Inside Every Casting

X-Ray Lab

X-Ray Inspection Room — 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 — without cutting, sectioning, or any damage to the part.

Internal defects that are completely invisible on the surface — porosity clusters, shrinkage cavities, cold shuts, foreign inclusions, and subsurface cracks — are clearly revealed and documented before shipment.

Chemical Composition Analysis

OES Spectrometer — Alloy Verification at Source

Every incoming ingot is verified against the specified alloy grade before it enters production. The Hitachi FMS delivers spark OES analysis in seconds — certifying elemental content with foundry-grade precision.
