What KONEC does

KONEC (코넥, KONEC co.,ltd.) is a privately held South Korean specialty die-casting manufacturer founded in 2003 and headquartered in Seosan, Chungcheongnam-do. The company designs and mass-produces high-pressure die-cast aluminum and magnesium automotive components — including EV Integrated Charging Control Units (ICCU), motor and inverter housings (FF/FR inverter, motor case), steering rack housings, hybrid converter housings, automatic transmission valve bodies, timing chain cases, and engine cylinder blocks — for global automotive OEMs and Tier-1 suppliers. Its core technology stack combines vacuum and partial-squeeze die-casting for pressure-tight parts, magnesium high-pressure die-casting for lightweighting, friction stir welding (FSW), helium leak testing, and a forward-looking R&D portfolio in hybrid casting, fluidic core processes, smart molds with real-time temperature/pressure sensing, and IoT/ICT stereo-camera sensing modules.

KONEC operates a four-country footprint: its Seosan headquarters and main plant in Korea, the Suji (Yongin) R&D Center, a wholly-owned U.S. subsidiary KONEC Houston (est. 2023) serving TESLA's North American programs, the Rizhao Konec joint venture in Shandong, China (est. 2013) for localized Chinese-market production, and a German research laboratory (est. 2021) supporting European Tier-1 customers such as ZF. The company holds IATF 16949, ISO 14001, ISO 22301, ISO 45001, and Aluminum Stewardship Initiative (ASI) Performance Standard certifications, and has been recognized with multiple Korean Presidential technology awards (2015 Korea Technology Awards Grand Prize, 2017 and 2024 Presidential Citations).

KONEC's business model is direct enterprise contract manufacturing: the company sells bespoke die-cast components under multi-year platform supply agreements with named OEMs including TESLA (Model 3/Y, Cybertruck, Mega Pack Front Plate), Hyundai Motor Company, Hyundai Mobis, Hyundai Transys, WIA (Theta-2 cylinder block), and Germany's ZF (steering components). Pricing is negotiated contract-by-contract and is not publicly disclosed. Revenue is concentrated in EV drivetrain components where lightweighting, internal-pressure tolerance, and dimensional precision drive OEM selection; the company's explicit R&D roadmap targets one-piece car-body casting (차체일체주조) and FRONT-RUNNER Tier-1 status by 2027.

Revenue model

1. Auto parts contract manufacturing (die-cast and machined components): Primary revenue stream. KONEC designs, develops, and mass-produces die-cast aluminum/magnesium automotive components (EV ICCU, motor/inverter housings, valve bodies, cylinder blocks, timing chain cases, steering parts) under supply contracts with global OEMs and Tier-1s. Contracts span multi-year platform lifecycles (e.g., TESLA Model 3/Y, Cybertruck, Mega Pack Front Plate).

Core offering

KONEC designs, develops, and mass-produces high-pressure die-cast aluminum and magnesium automotive components — including EV drivetrain housings (ICCU, motor case, inverter housings, rack housing), hybrid converter housings, transmission valve bodies, timing chain cases, and engine/cylinder blocks — for global OEMs and Tier-1 suppliers. Production is supported by integrated CNC machining, friction stir welding, and helium leak testing, with research targeting hybrid casting, fluidic core processes, smart molds, and one-piece car-body casting.

Product overview

KONEC's offering is a single unified manufacturing capability rather than a software platform-plus-modules architecture: high-pressure aluminum (and magnesium) die-casting of automotive structural and powertrain components, complemented by in-house CNC machining, Friction Stir Welding (FSW), and helium / differential-pressure leak testing. The marketed portfolio (EV ICCU, EV Rack Housing, EV FF Inverter, EV FR Inverter, EV Motor Housing, Hybrid Converter Housing, Timing Chain Case, Cilinder Block, Valve Body) is a set of die-cast sub-products — not a product family with a common brand — served by the same die-casting process platform and supported by the Seosan (Korea) headquarters plant, the Jukjeon (Suji) R&D Center, the Germany research lab, KONEC HOUSTON (USA), and Rizhao KONEC (China) joint venture.
