We have acquired “Nadcap Certification” in the processes of heat treatment, welding/brazing, surface treatment, and nondestructive inspection, and can also perform special processes of aircraft parts.


What’s Nadcap?
Nadcap is the sole international certification system for special process management in the aerospace industry, which was established by the PRI (Performance Review Institute), an affiliated organization of SAE in the United States. Currently, major manufacturers such as Boeing and Airbus outsource the review of their suppliers’ manufacturing processes to PRI.
It is an industry-operated special process certification system that was established with the aim of continuous improvement and efficiency of certification by unifying requirements for the review of suppliers, which had been carried out individually by major manufacturers.
More than 10 processes including heat treatment, welding, surface treatment, and nondestructive inspection are certified, and strict requirements are set with an emphasis on examining the actual treatment at the site.
