Why Can We Always Ensure Excellent Quality

Quality Control

Our vertically integrated QC infrastructure ensures every accessory meets international standards from raw material intake to final shipment. Implemented under ISO 9001:2015 framework, we maintain 99.7% customer acceptance rate through 4-tier inspection protocols:

**1. Material Qualification**
- Spectrometer testing for metal alloy composition verification
- Batch-level certification for polymers (FDA/EN71-3 compliant)
- Moisture content analysis for resin/ceramic raw materials

**2. In-Process Monitoring**
- Real-time dimensional checks via laser measurement (±0.1mm tolerance)
- Automated color consistency monitoring with Pantone QC software
- Stress test simulations for chain/clasp durability (5,000+ open/close cycles)

**3. Finished Product Inspection**
- 100% visual examination under 10x magnified LED light stations
- Functionality tests:
• Magnetic closure strength (≥1.2kg pull force)
• Electroplating thickness (Nickel: 8-12μm, Gold: 0.25μm)
• Enamel adhesion (cross-cut test per ASTM D3359)
