Quality Control

The eight procedures behind every part we ship.

Deferry continues to pursue and establish our own levels of quality control. Our goal is straightforward: keep defects low across our entire product line, and maintain state-of-the-art laboratory facilities to ensure comprehensive product and manufacturing integrity.

In conjunction with new product design, analytical methods are continually refined so that performance is maintained at the highest levels. In 2015 Deferry obtained ISO 9001 and ISO 14001 certificates, and built a strict and precise quality control system to secure quality requirements in every procedure.

Control Steps

  • Incoming inspection
  • Production monitoring and procedure controlling
  • Measurement tools monitoring
  • Failure mode and effects analysis
  • Error management
  • Complaints handling
  • Data storage and data backup
  • Quality management system
