With advanced 3D printing, our turbine blades redefine manufacturing—delivering faster development, higher efficiency through superior quality, and innovative design freedom.

Engine Start Begins with ATS. The Air Turbine Starter (ATS) is a key component of an aircraft's secondary power system, driven by Bleed Air supplied from the Auxiliary Power Unit (APU) to accelerate the engine up to approximately 8,900 RPM, enabling engine start. Through the in-house development and localization of the ATS, we have incorporated power generation, optimal design of the shear section with consideration of failure, Containment functionality, as well as lubrication and power transmission systems. In addition, we have secured manufacturing and assembly technologies and continue development aimed at successful operation and the establishment of a mass production system.

Air conditioning units are designed for efficiency, durability, and environmental control, our units help ensure smooth ground handling and turnaround operations in all weather conditions Whether servicing commercial planes or private jets, our units deliver powerful and precise cooling and heating to ensure comfort for passengers and crew.

The Bombardier Global 8000 aircraft, set to enter into service in the second half of 2025, is the fastest and farthest flying business jet in the industry. The Global 8000 aircraft can be outfitted with secure communications, navigation and self-protection systems.

QPL certification is a system in which the US government guarantees the quality only for products that have passed strict local company inspections made of 150 tests and verifications under the supervision of the US government. Yeonhab Precision obtained the certification in Asia for the first time after 10 years of application. In particular, with the successful QPL registration for the first time in Asia, Yeonhab Precision is the first and only company in Asia which got the qualification of marking “MS” with the title of “Korea’s first MIL-DTL connector”. We will provide customers with the best products as we have the sense of the pride of developing the QPL certified connector with our own technology in Korea.

It is a product lineup that is proven in global markets and has world-class competitiveness. And it is being exported to more than 20 countries around the world.
