Sewon Precision, founded in 1985 as a core affiliate of the Sewon Group, is a KOSPI-listed auto parts maker focused on body/chassis components.
Its main products are core body parts such as front side members, cowl cross members, and dash panel assemblies, supported by process technologies including laser welding and closed-section composite forming.
Beyond body parts, the company has expanded into interior/exterior injection-molded plastic parts and lamp components (design modules), molds needed for parts production, and high-performance multilayer sheets.
Its body-parts lineup includes front side members, cowl cross members, dash panel assemblies, radiator panel assemblies, and rear floor components, supported by closed-section composite forming systems and precision laser welding technology.
Its primary customer is the Hyundai Motor Group, and domestically Sewon Precision shares body/design-part production with affiliates Sewon Mulsan, Sewon Tech, and Sewon ENI.
Founded in 1985, Sewon Group has maintained competitiveness through cooperation with Hyundai Motor Group, producing body and design parts domestically via Sewon Precision, Sewon Mulsan, Sewon Tech, and Sewon ENI.
Its overseas manufacturing network spans China (Samha Sewon, Huanghua Sewon) and the United States (Sewon America), with Sewon America established in LaGrange, Georgia in 2008 to supply body parts to North American automakers.
Sewon America was established in LaGrange, Georgia in 2008 to supply body parts to the North American market. More recently, the company built a dedicated Georgia production base timed to Hyundai's US EV-dedicated plant startup.
Hyundai Motor Group's US EV-dedicated plant, HMGMA, was completed in early 2025, and Sewon Group co-located there to fully launch parts supply. Given its heavy reliance on a single automotive group, results are highly sensitive to industry cycles and shifts in the customer's production and sourcing policies.
