Recently, Guizhou Company successfully completed the Nadcap audit for eight of its surface treatment processes, including cadmium plating, silver plating, stainless steel passivation, sulfuric acid anodizing, chemical oxidation, pulse anodizing, dry film lubricant, and aluminum coating. The review was conducted by the PRI audit team, and the certification was extended for another six months. This achievement marks a significant milestone for Guizhou Company as it strengthens its position in the global aerospace market.
Nadcap is a globally recognized certification program specifically designed for the aerospace industry. It serves as a prerequisite for major aviation companies like Boeing and Airbus. Every year, the PRI (Performance Review Institute) conducts annual audits to ensure compliance with strict quality standards. In February this year, a two-month Nadcap audit was carried out at Guizhou Company’s facility. The audit team thoroughly reviewed the company’s production processes, quality management systems, and technical documentation. After a comprehensive evaluation, the audit concluded that all eight surface treatment projects met the required standards, leading to the successful certification.
This accomplishment not only enhances the company's credibility but also opens up new opportunities for international collaboration and business expansion. As part of its commitment to quality, Guizhou Company continues to invest in advanced testing and certification processes.
In addition, the Aerospace Seiko Guizhou Company Testing Center recently passed verification by the CIIC Guojin International Laboratory. This marks another important step in the company's pursuit of excellence in product testing and quality assurance.
The CIIC International Laboratory Proficiency Testing Center (NIL) is a well-established institution that provides laboratory proficiency testing and measurement auditing services. It has been accredited by the China National Accreditation Service for Conformity Assessment since 2003 and is one of the first independent third-party entities in China to hold such qualifications. In 2014, the center began offering capability verification services, and Guizhou Company’s Testing Center participated in four pilot projects across 12 sub-projects. These included metal tensile testing at room temperature, Rockwell hardness testing, decarburization depth measurement in steel, and chemical composition analysis in low-alloy steel. All tests were completed successfully, demonstrating the high level of expertise and reliability of the testing center.
As a key department responsible for product performance evaluation, the Testing Center plays a vital role in ensuring product quality, consistency, and compliance with industry standards. It handles a wide range of testing tasks, including quality supervision, product identification, process validation, and quality assurance. This ongoing commitment to rigorous testing supports the company’s long-term growth and reputation in the aerospace sector.
