AERO COTEC Corporation was founded in 1989 in Bongam-dong, Masan-si. In 2008, we established a specialized surface treatment factory for defense and aerospace components in Sacheon-si, Gyeongsangnam-do. In 2019,
we were separated as a corporation from the parent company, COTEC Corporation, leveraging our talent and technical capabilities. We are a leading company in the global aerospace and defense market.

Our company holds approximately 800 approval certificates from customers such as BOEING, AIRBUS, BOMBARDIER, EMBRAER, SAFRAN, KAI, KAL, based on Aerospace Standard for Quality Management System (AS9100 (KS Q9100)), National Aerospace & Defense Contractor Accreditation Program (Nadcap), and Korea Special Process Certification (KSPC).

Our company possesses machining technology for critical components such as SHAFT, GEAR, BUSH, and ACTUATOR, which are integral parts of LANDING GEAR and DOOR STRUCTURE.
We also specialize in various surface treatment technologies, including IVD, HVOF, and SFL, as well as hard chromium plating, anodizing, chemical milling, zinc plating, electroless nickel plating, and magnesium anodizing, totaling 35 different surface treatment techniques.
Leveraging these capabilities, we have established an in-house production line (ONE-STOP SERVICE) that can undertake batch production of components and sub-assembly units based on our expertise.
