- 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)
