Recently, Guizhou Company's eight surface treatment processes—cadmium plating, silver plating, stainless steel passivation, sulfuric acid anodizing, chemical oxidation, pulse anodizing, dry film lubricant, and aluminum coating—successfully passed the Nadcap audit conducted by the PRI audit team. The certification was extended for another six months, marking a significant milestone for the company in its international expansion efforts. This achievement highlights the high standards of quality and process control maintained by Guizhou Company, making it more competitive in the global aerospace market.
Nadcap is a globally recognized certification program specifically designed for the aerospace industry. It serves as a prerequisite for many top-tier aviation companies, including Boeing and Airbus. To maintain their certification, companies must undergo annual audits by the PRI, which assesses both the quality system and the technical capabilities of each process. In February this year, a team of Nadcap auditors spent two months reviewing Guizhou Company’s surface treatment processes. They closely monitored the production line, evaluated documentation, and ensured compliance with international standards. Their final conclusion was that all eight projects met the required criteria, allowing the company to retain its Nadcap certification.
This accomplishment not only strengthens Guizhou Company’s reputation but also opens up new opportunities for collaboration with major aerospace manufacturers around the world. (By Yang Biao)

In addition to the Nadcap success, the Aerospace Seiko Guizhou Company Testing Center recently achieved another important milestone by passing the verification of the CIIC Guojin International Laboratory. This certification confirms the center’s capability to perform accurate and reliable testing, further enhancing its credibility in the industry.
The CIIC International Laboratory, also known as NIL, is a leading institution in laboratory proficiency testing and measurement auditing. Accredited by the China National Accreditation Service for Conformity Assessment in 2003, it became one of the first independent third-party entities in China to offer verification services. In 2014, the laboratory expanded its scope to include capability verification, and Guizhou Company’s Testing Center participated in 12 sub-projects across four pilot programs. These included metal tensile tests at room temperature, Rockwell hardness testing, decarburization depth analysis in steel, and chemical composition analysis of low-alloy steel. All tests were completed successfully, demonstrating the high level of expertise and precision of the testing team.
As a key department responsible for product performance evaluation, the Testing Center conducts a wide range of inspections, including quality supervision, product identification, process validation, and consistency checks. This ensures that all products meet the required standards before they reach the market. (By Fu Guoguo, Wang Lei)
