Serviços de fundição de espuma perdida para componentes metálicos de precisão

Delivering advanced lost foam casting solutions for complex and high-precision metal components. Our expertise covers railway bogie parts, automotive steel and ductile iron components, electrical stator press rings, e equipamentos industriais, with guaranteed dimensional accuracy, excellent surface finish, and consistent quality.

What is Lost Foam Casting?

Fundição de espuma perdida, 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: Aço, aluminum, ferro dúctil, and specialty alloys
• Cost Efficiency: 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 & Revestimento – 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. Casting – Molten metal poured, foam pattern vaporizes, leaving near-net-shape casting
5. Cleaning & Tratamento térmico – Sand removal, tratamento térmico, and machining as required
6. Garantia de qualidade – Dimensional inspection, teste de dureza, metallographic analysis

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

Materials We Work With

• Aço: Aço carbono, liga de aço, stainless steel
• Ferro Dúctil: For high-strength structural components
• Specialty Alloys: Tailored to project requirements

Nós também fornecemos material selection guidance based on load, function, and environmental requirements.
