Precision Metal Components with or Without Tooling

Lost Foam Casting

Skuld is the world leader in lost foam investment casting.

Whether making ductile iron 1mm thick when world class is 4mm, casting steel, nickel, and other materials in lost foam, or developing cast versions of wrought grades like 6061 and 7075, Skuld is able to provide a more efficient means of net or near net casting.

Why It Works

Lost foam casting replaces multiple steps in conventional casting with a single, efficient pour.

The pattern disappears as the metal enters, allowing for shapes that are impossible to machine or assemble. It achieves near-investment-casting precision without the slow, multi-layer ceramic process.

Tight tolerances: ±0.003 inch per inch typical

Thin-wall sections: Down to 0.7 mm in ductile iron

High surface quality: Comparable to investment casting

Versatile alloys: Aluminum, iron, steel, and nickel alloys

From Legacy Process to Next-Gen Innovation

Bridging traditional foundry craft with digital manufacturing.

Lost foam casting laid the foundation for Skuld’s patented AMEC® process — a hybrid technology that merges polymer 3D printing with evaporative casting. The result is faster production, tighter precision, and new possibilities for modern metal manufacturing.

Lightweighting

ACCURACY, precision, and performance — all built in.

Thin walled foam enables lightweighting redesigns in a wide range of alloys.

Combined with proprietary ductile iron alloying combine to produce TWDI where others can only produce brittle iron carbide.

Enabling lightweighting redesigns that often save as much as 70-80% of the weight as well as costing less.

Applications include valves, structural components, brake calipers and other vehicle parts, and now the BIFROST bridging system in development for the Marines.
