What Daesung Hi-Tech does
Daesung Hi-Tech is a privately held Korean automotive parts manufacturer founded in 1987 as Daesung Chemical, headquartered in Cheonan, Chungcheongnam-do, South Korea. The company specializes in three integrated product categories: rubber components (grommets, O-rings, seals, and eco-friendly TPE parts using EPDM and silicone compounds), wiring harnesses and extensions (including EPB, WSS, EPS, ECS systems plus EV-specific NACS, CCS, and V2L harnesses), and insert molding components (MOLD CONN, CONN COVER, TPE GROMMET). Core technology centers on proprietary thermoplastic elastomer (TPE-100) formulations developed with Korean government support, custom insert molding mold designs, and a KOITA-certified in-house research institute, supported by 20+ patents covering materials, processes, and product designs.
The company operates as a direct B2B supplier to automotive OEMs and Tier-1 integrators, with all pricing negotiated privately under multi-year supply contracts. Its primary customer relationships are with Hyundai Motor Company and Kia Motors, holding SQ-MARK certifications across five product categories (rubber, injection molding, wiring, welding, electronic soldering), and with Continental as a Tier-1 customer (ABS Sensor Harness supply). Manufacturing is distributed across five facilities in South Korea (Cheonan HQ, Pyeongtaek), China (Qingdao via Qingdao Nanjing Electronics subsidiary established 2004), and Vietnam (Thanh Hoa via DS HI-TECH VINA subsidiary established October 2020, with a second factory under construction as of November 2025). Products are exported to 19 countries including the United States, China, and Japan.
The business model is contract manufacturing with hardware sales revenue under OEM specification, no public pricing, and just-in-time delivery to assembly lines. The company has positioned itself for vehicle electrification through its Eco EV Components line covering high-voltage harnesses, V2L adapters, and battery pack rubber sealing. Leadership rests with CEO Jeong Jin-han, and ownership is private and family-controlled with no disclosed institutional investors. Beyond core manufacturing, the company has begun strategic capital deployment, participating as a new investor in Tesollo's June 2026 Series B funding round for robotic hand technology.
