What is Lost Foam Casting?

Moulage de mousse perdue, also called evaporative pattern casting, is a modern metal casting method where a foam pattern is replaced by molten metal. The process allows for:

• Complex Geometries: Ideal for intricate internal cavities, undercuts, and detailed surfaces
• Reduced Machining: Smooth surface finish minimizes post-processing
• Material Flexibility: Acier, aluminum, fonte ductile, and specialty alloys
• Rentabilité: Suitable for low to medium-volume production

Typical dimensional tolerance for lost foam castings is ±0.5–1.0 mm, depending on component size and material.

Our Lost Foam Casting Process

Our automated lost foam casting production line ensures high quality and efficiency:

1. Pattern Design & Fabrication – Precision foam patterns based on CAD models, optimized for minimal defects and metal usage
2. Pattern Assembly & Coating – Foam patterns assembled and coated with refractory material for surface quality and thermal resistance
3. Molding – Patterns placed in dry sand molds, compacted to maintain dimensional stability
4. Fonderie – Molten metal poured, foam pattern vaporizes, leaving near-net-shape casting
5. Cleaning & Traitement thermique – Sand removal, traitement thermique, and machining as required
6. Assurance qualité – Dimensional inspection, essai de dureté, metallographic analysis

This process enables production of high-quality steel, fonte ductile, and aluminum components with excellent repeatability and surface finish.

Materials We Work With

• Acier: Acier au carbone, acier allié, stainless steel
• Fonte Ductile: For high-strength structural components
• Specialty Alloys: Tailored to project requirements

Nous fournissons également material selection guidance based on load, function, and environmental requirements.

Industries & Applications

Our lost foam casting services are trusted across multiple industries:

• Chemin de fer: Bogie frames, roues, parenthèses, and structural castings
• Automotive: Gearbox housings and structural components in steel and ductile iron
• Industrial Machinery & Energy: Valves, pump housings, wind turbine parts, and construction machinery components
• Electrical Components: Stator press rings – part of our production now uses lost foam casting for precise geometry and smooth surface finish
• Custom Projects: Rapid prototyping, low-volume production, and highly complex designs

Whether you need a single prototype or a production series, we deliver high-quality castings that meet your specifications.
