Founded in 1986 and listed on KOSDAQ in 1992, Ilji Tech is a specialized manufacturer of automotive body parts. Its core products are panels that form the vehicle frame, including dash, hood, door, side, and floor components, produced through an integrated press-weld-assembly system.
The company's primary customer is Hyundai Motor Group, for which it holds Tier-1 supplier status, and it also operates a mold-making business.
Domestic production is based at two plants in Gyeongsan and one in Gyeongju, North Gyeongsang Province, while overseas operations run through a subsidiary in Beijing, China, and a US subsidiary, ILJI TECH AMERICA INC.
The company expanded its North American business in 2023 by acquiring additional equity in a US body-parts manufacturer, and according to a report by Research Alum, roughly 64% of 2025 revenue was generated in the United States.
More recently, the company has broadened its product lineup to include battery module cases and battery cooling systems for eco-friendly vehicles as part of its electrification response.
The body-parts segment has high barriers to entry due to the scale of capital investment and manufacturing know-how required, with peers such as Sungwoo Hitech, Dongwon Metal, and Myoung Shin Industrial cited as comparable players in the sector.
