Sichuan Easy Vision Photoelectric Technology Co,.Ltd Quality Control

1. Quality Management System Certification
Certified under ISO 9001 Quality Management System to ensure standardized and regulated production processes.
Selected products comply with CE, RoHS, FCC, and other international certifications, meeting global market requirements.
2. Raw Material & Supply Chain Control
Strict supplier screening to ensure key materials (optical glass, coating materials, electronic components, etc.) meet industry benchmarks.
Incoming materials undergo spectral analysis, mechanical performance testing, and environmental adaptability testing to prevent defective materials from entering production.
3. In-Process Quality Control
Precision Machining Control: High-precision CNC machines, optical coating systems, and auto-focusing equipment ensure critical parameters (surface accuracy, roughness, coating uniformity) meet specifications.
Assembly Process Control: Optical system assembly is conducted in cleanrooms to prevent dust contamination.
In-Process Quality Checks (IPQC): Each production stage includes inspection checkpoints for real-time monitoring of key parameters (e.g., optical axis deviation, MTF, distortion rate).
4. Finished Product Testing & Reliability Validation
Optical Performance Testing: Professional equipment such as MTF testers, interferometers, and spectrophotometers verify resolution, transmittance, and aberrations.
Environmental Durability Testing: Products undergo thermal cycling (-40°C to 70°C), humidity resistance, vibration, and shock tests to ensure stability in extreme conditions.
Lifespan Testing: Simulates long-term usage to validate durability and reliability.
5. Customer Feedback & Continuous Improvement
A post-sales quality tracking system collects customer feedback for rapid issue resolution.
PDCA (Plan-Do-Check-Act) cycle implementation for ongoing process and design optimization.
6. Expert Team & Automated Inspection
A dedicated optical QC engineering team oversees quality assurance, supported by AI vision inspection and automated testing for enhanced accuracy and efficiency.
