JNT Group Chairman Sangwook Jang's motto

Securing world-class technological competitiveness
through continuous innovation and technology development

With continuous future technology development, Jinwoo Engineering(JNTE) is writing a new history of technological evolution. Jinwoo Engineering(JNTE) has developed the core machine equipment and process systems that produce: 3D cover glasses that led the creation of edge phones; connectors for waterproof phones; and gas diffusers (GDL), commonly referred to as the 1% puzzle piece for localization of hydrogen electric vehicles. At the time of their debut, they were recognized as the only and unique technology in the world.
