DK-Lok in talks to supply global commercial aircraft maker, prepares for mass production with 17.5 billion won investment

[Financial News] Industrial fittings and valve specialist DK-Lok has secured 17.5 billion won in investment funding ahead of its entry into the global commercial aircraft components market. The company plans to extend into the civilian aircraft market the technological expertise it has built up supplying components for the KAI KF-21 Boramae fighter and the FA-50 light attack aircraft.
According to DK-Lok on the 11th, the company has signed a nondisclosure agreement (NDA) with global commercial aircraft manufacturer Company B and is discussing the supply of aviation fittings. Although a supply contract has not yet been finalized, DK-Lok is proactively strengthening its production and quality-control systems in preparation for future orders.
DK-Lok held a board meeting that day and decided to borrow 17.5 billion won. The amount is equivalent to 12.8% of its consolidated equity at the end of last year, and the company will use innovation and growth policy financing linked to the Korea Credit Guarantee Fund (KODIT). The funds will go toward securing raw materials for aviation fittings, product development, testing and verification, and strengthening its mass-production system.
The key aim of this investment is not simply to expand production capacity, but to make advance preparations for entering the global aircraft supply chain. For aviation components, quality certification and stable mass-production capabilities, as well as technical expertise, are considered key factors in supplier selection.
DK-Lok entered the aviation business in 2015 with government research and development (R&D) support. It secured aviation fitting technology by carrying out four R&D projects worth a total of $4 million, and has supplied certified components for Korea Aerospace Industries (KAI)'s KF-21 and FA-50 programs since 2020.
Starting this year, the company is pursuing the supply of QPL- and QML-certified components for a follow-on batch of 80 KF-21 aircraft. It also plans to expand the use of QPL-certified fittings on the FA-50.
DK-Lok has established a vertically integrated system in which it handles everything in-house, from forging and machining to surface treatment, testing and verification. Next year, it also plans to pursue Nadcap accreditation, a global aerospace quality certification, in chemical processing and coating.
The investment is expected to serve as an opportunity to diversify the company's business, currently centered on instrumentation fittings and valves, into semiconductors and aviation. In particular, if discussions with a global commercial aircraft manufacturer lead to an actual supply contract, the company is expected to gain momentum in securing a new growth engine.
An industry source said, “The aircraft components market requires considerable time for certification and mass-production validation even after the technology has been developed,” adding, “Whether experience supplying military aircraft can be carried over to the commercial aircraft market will be key to future growth.”
DK-Lok CEO No Eun-sik said, “We will use this policy financing as funding for proactive investment in future growth businesses, localize aviation fittings and strengthen our mass-production competitiveness,” emphasizing, “We will expand cooperation with global customers and develop the aviation business into a new growth engine.”
