Semyung Engineering was founded on advanced precision machining technology for metallic materials, building a stable technical foundation through accumulated machining expertise, skilled engineering personnel, and a wide range of manufacturing facilities. Since our establishment, we have focused on producing and supplying high-precision components for defense industries, aircraft parts, and tooling—fields that require exceptional accuracy and reliability.
In 2019, we established our corporate research institute to reinforce technological development and new product innovation, and in the same year, we acquired the AS9100 Rev D Aerospace Quality Management System certification, meeting international quality standards required in the defense and aerospace sectors. Based on this system, we continue to focus our capabilities on the precision machining of aerospace and defense components.
To meet the growing demand for large-scale machining, we have continuously invested in dedicated equipment for producing large and complex components, expanding our capabilities in high-difficulty and large-format precision machining. Moving forward, Semyung Engineering will further strengthen its position as a precision machining specialist, advancing our technology and facility capabilities to deliver high-quality, high-precision solutions that meet the needs of our customers.
