Core offering

Hanjoo Light Metal manufactures aluminum die-cast automotive components through proprietary casting technologies (ESDC, LPDC, GDC, and dissimilar metal bonding), supplying engine, chassis, EV battery case, and marine propulsion parts to global automotive OEMs and Tier-1 suppliers. The company operates a one-stop process spanning CAD/CAE design, casting, precision machining, assembly, AI-based X-Ray inspection, and direct shipment from plants in South Korea (Ulsan) and Slovakia.

Product overview

Hanjoo Light Metal is an aluminum die-casting specialist with 40 years of experience offering a comprehensive portfolio of casting technologies and manufactured components. Their core offerings include four proprietary casting technologies: ESDC (Electro-Magnetic Stirring Die Casting) for high-strength automotive knuckles and carriers; LPDC (Low Pressure Die Casting) for EV battery cases (1M+) and hollow side members; GDC (Gravity Die Casting) for engine components; and Dissimilar Metal Bonding for hybrid brake discs. Product portfolio spans EV Components (motor housing, battery cases, inverters), Lightweight Components (knuckles, carriers, subframes), Engine Components (EGR, manifolds, 3,000+ types), and Marine Propulsion Components. Operations are supported by in-house machining & assembly (103 facilities, 2M units/year capacity), testing & validation (AI-powered X-Ray/CT inspection, 3D measurement), and design & engineering services (CAD/CAE capabilities). Manufacturing facilities include Hwasan Plant, Wonsan Plant, and Slovakia Plant.

Products and services

• ESDC (Electro-Magnetic Stirring Die Casting) Semi-solid die casting method that uses electromagnetic force to induce nucleus generation, structure modification, and spherodization during molten metal solidification, producing high-pressure and high-ductile aluminum components for automotive OEMs and Tier-1 suppliers.
• LPDC (Low Pressure Die Casting) - Side Member / Hollow Subframe Low-pressure die casting process for manufacturing hollow-type automotive sub-frame side members with internal cooling channels, delivering ultra-lightweight chassis components with improved NVH for automotive OEMs.
• LPDC (Low Pressure Die Casting) - Large EV Battery Case Large-scale low-pressure die casting capability using multi-stroke force stepping technology to manufacture aluminum EV battery cases exceeding 1 meter in size, reducing component count and welding requirements for electric vehicle OEMs.
• GDC (Gravity Die Casting) Gravity die casting service for approximately 3,000 types of aluminum components including housings, pipes, and tubes for automotive fuel, intake/exhaust, and cooling systems.
• Dissimilar Metal Bonding Technology (Hybrid Brake Disc) Proprietary casting technology that bonds gray cast iron friction areas with aluminum alloy HAT components in a single cast to produce ultra-lightweight hybrid brake discs and cross members with 25% weight reduction versus conventional designs, sold to automotive OEMs and Tier-1 suppliers.
• EV Components Aluminum die-cast EV components including motor/generator housings with water-cooled circuits, mount brackets, large battery cases (1m+) produced via low-pressure casting, front covers, and inverter housings for power conversion, sold to electric vehicle OEMs and Tier-1 suppliers.
• Lightweight Components Ultra-lightweight aluminum automotive components including 4-cavity low-pressure cast knuckles, semi-solid electro-stirring cast carriers, dissimilar-metal bonded hybrid disc brakes, center floor tunnels, and sub-frame side members for OEM lightweighting programs.
• Engine Components Aluminum die-cast engine components including EGR housings, manifold assemblies, water temperature control (WTC) housings, transmission oil pump covers, and intake manifolds for fuel, intake/exhaust, and cooling systems across approximately 3,000 component types.
• Marine Propulsion Components Aluminum outboard marine propulsion components including swivel brackets, pedestals, intake manifolds, exhaust manifolds, and exhaust pipes manufactured via low-pressure and gravity casting with cores, supplied to marine engine OEMs including Mercury Marine since 1997.
• Machining & Assembly Precision machining and assembly service spanning small to large items with 103 three-axis processing facilities (MCT, TCT, CNC) producing 2 million products per year, including washing, sealing, leak testing, and function tests, supporting the company's vertically integrated one-stop manufacturing model.
• Testing & Validation Quality assurance and testing service covering 3D size inspection, X-Ray testing, CT testing, AI-based automatic defect recognition (ADR), 3D scanning, impact testing, and fatigue testing, integrated into the company's cast-component supply flow for OEM and Tier-1 customers.
• Design & Engineering Product design and engineering service offering CAD (CATIA, Siemens NX, CREO, Pro/Engineer, AutoCAD, SolidWorks), CAE simulation (ABAQUS, AnyCasting, Z-Cast Pro, SIGMA), casting analysis, and mold design optimization for automotive OEM and Tier-1 customers.
