Precision Metal Components with or Without Tooling

Lost Foam Casting

Skuld’s lost foam casting process produces complex, net-shape metal parts directly from polymer or foam patterns — joined or single — that vaporize as molten metal fills the mold.

The result is a cleaner, faster, and more flexible alternative to traditional foundry methods, with optional tooling for higher-volume production.

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.

Faster. Cleaner. More Capable.

Agility, precision, and performance — all built in.

Because no tooling is required, design changes are simple and lead times are short.

Lost foam enables faster iteration, reduced waste, and greater freedom in part geometry.

It’s ideal for lightweighting, reverse engineering, and modern manufacturing programs where speed and adaptability matter.

Applications include housings, brackets, structural components, and parts that demand precision and strength without the cost and delay of traditional processes.
