Strict Quality Control: How KDC improves the yield of rearview mirrors?
Precision You Can See – Quality Begins with Control
At KDC Auto, every rearview mirror reflects more than just what’s behind—it reflects our commitment to quality.
From material selection to optical inspection, our strict quality control (QC) process ensures that each mirror meets global standards and customer expectations. Through continuous improvement and innovation, KDC Auto has successfully achieved a high yield rate while maintaining the safety and precision demanded by the automotive industry.
Why Is Quality Control Critical in Rearview Mirror Manufacturing?
A rearview mirror is more than a visual accessory; it’s a safety-critical component. Any minor distortion, uneven coating, or bonding defect can lead to serious visibility issues.
That’s why KDC Auto implements multi-stage inspections—covering optical accuracy, adhesion, vibration resistance, and reflective performance—to ensure every mirror leaving the factory is reliable under all driving conditions.
🪞 “For KDC, quality isn’t an act—it’s a system.”
How Does KDC Improve the Yield Rate of Rearview Mirrors?
Our approach to yield improvement is rooted in precision control and data-driven management.
Key Steps in Our QC Process:
🔍 Incoming Material Inspection: Raw materials such as glass, backing plates, and coatings are tested for consistency and optical flatness.
⚙️ Process Monitoring: Each production stage—cutting, coating, bonding—is digitally tracked to detect deviations in real time.
🧪 Automated Optical Testing: High-resolution sensors measure curvature, reflectivity, and color accuracy of every rearview mirror.
🧰 Defect Prevention Analysis: Using SPC (Statistical Process Control) and FMEA (Failure Mode & Effects Analysis), we identify root causes before issues occur.
🔄 Feedback Loop: Data from QC is immediately fed back to production to fine-tune parameters, ensuring stable yield.
What Standards Does KDC Follow to Ensure Consistency?
KDC Auto operates under ISO 9001:2015 and IATF 16949:2016 certification frameworks, guaranteeing traceability and reliability in every step.
Our mirrors meet or exceed ECE R46 (for European vehicles) and FMVSS 111 (for U.S. markets) safety standards, ensuring global compliance.
These standards guide how we:
Maintain uniform optical clarity
Reduce defect rate through controlled environments
Improve repeatability of mass production
The Human Factor Behind the Precision
Technology is only as strong as the people who use it.
Our manufacturing team—trained in both optical measurement and assembly techniques—works with a “zero-defect” mindset.
Every mirror passes a manual final inspection, where experienced technicians verify surface quality, mounting precision, and reflection accuracy by hand.
This people-centered approach ensures that KDC Auto’s mirrors don’t just meet expectations — they surpass them.
From Data to Perfection
Through strict quality control, digital inspection systems, and human craftsmanship, KDC Auto continuously improves yield, stability, and trust.
Each rearview mirror produced represents the synergy between precision manufacturing and Taiwanese engineering excellence — qualities that make KDC a trusted partner for automotive brands worldwide.
