Our Quality Control Process

Every component undergoes rigorous inspection and testing to ensure dimensional accuracy, material integrity, and surface perfection.

Quality Inspection

1. Material Verification

All raw materials are tested for hardness, composition, and grain structure before processing.

2. In-Process Inspection

CNC and EDM operations are monitored in real-time with digital calipers, micrometers, and CMM checks.

3. Final Dimensional Check

Each part is measured against CAD drawings with tolerances as tight as ±0.001mm.

4. Surface & Finish Testing

Mirror polishing, EDM texture, and plating are verified under magnification and gloss meter.
