We offer Korean forging, casting and stamping capabilities that are specially designed for the automotive, machinery, petrochemical, and oil & gas industries. Equipped with state-of-art machining centers and inspection systems, all of our forging, casting and stamping facilities are certified to ISO/TS 16949 or ISO/ASME standards. Each manufacturing site has engineers, technicians and tradesmen with over 20 years of in-depth experience with different materials, part shapes, and heat or surface treatments.

Due to our advanced cold forging, precision casting and stamping capabilities, we are a long-time supplier to global auto makers, Tier 1 suppliers to auto makers, and machine manufacturers. We also perform hot forging, and are a global hemi head supplier to pressure vessel manufacturers in the petrochemical, oil and gas industries.

Cold Forging, Hot FormingPDF Icon and Metal Stamping 

Forged and Stamped Engine, Transmission, Chassis Components

Our rich experience in the automotive industry has enabled us to cover a wide range of forging products for brake systems, including spindles for caliper assembly, steering columns and suspension systems. We have now expanded our custom manufacturing services to clients in the machine manufacturing and medical industry. Our decades of knowledge and experience translate into material cost savings, reduced machining, and innovative technology, allowing us to stay competitive.

During the design stage we use 3D simulation tools to analyze the metal forming process and material stress. Our manufacturing processes are quality controlled by deploying Cold Forming 3 View, Auto Checker and Cross Thread Physical Checks. Each manufacturing facility is equipped with a computerized lot-tracking system, an ERP-integrated tooling life tracking system, and cutting-edge testing equipment.

    Iron Casting for Automotive Parts

    Our iron casting manufacturer, Daehan Special Metal Co., Ltd (DSM), has a 44 year history as the one-stop iron casting solution provider for the automotive, industry, and for marine and power generation industry. Started as an iron foundry in 1973, it grew to become a global supplier of great precision iron castings for the automotive industry.  DSM currently has seven foundry facilities, cutting edge production and machining centers and testing equipment. Their iron casting facilities use different casting methods to manufacture iron castings from small sizes of automotive parts.

    It holds patents on many casting technologies such as Melting and Sand Bonding for Iron Castings; Coupler Structure and Design for Spiral-Shaped Steel Coils; Coupler Production Process for Spiral-Shaped Steel Coils; FG Coupler for Steel Connectors; the Design of FG Couplers for Steel Connectors; and for the Method and Apparatus of Connecting Spiral-Shaped Steel Coils. DSM’s production lead time from receiving drawings to finished products, including quality testing, can be as short as four weeks.

    Encompassing gray cast and ductile iron as its main casting materials, DSM’s thermal analysis program uses ATAS dynamic inoculation to identify optimum melting condition for ductile cast iron and gray cast while using FEMAP and residual stress simulation software to check on any deformation or stress from heat.

    Each project manager is able to monitor each process and to track production lead time since DSM’s manufacturing process data are automatically logged and get sent to the central control system.

    A typical manufacturing process consists of nine steps:

    • 1. Preparing Patterns
    • 2. Melting
    • 3. Sand Molding
    • 4. Closing Molds by Cope and Drag method
    • 5. Pouring Molten Material into a Sand Mold
    • 6. Separating Casting From a Sand Mold
    • 7. Degating Inlets and Risers
    • 8. Shot Blasting and Deburring
    • 9. Final Inspection of the Casting
