What is Lost Foam Casting?

Литье по выплавляемым моделям, 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: Сталь, алюминий, ковкий чугун, 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 & Coating – Foam patterns assembled and coated with refractory material for surface quality and thermal resistance
3. Молдинг – Patterns placed in dry sand molds, compacted to maintain dimensional stability
4. Кастинг – Molten metal poured, foam pattern vaporizes, leaving near-net-shape casting
5. Cleaning & Термическая обработка – Sand removal, термическая обработка, and machining as required
6. Гарантия качества – Dimensional inspection, испытание на твердость, металлографический анализ

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

Materials We Work With

• Сталь: Углеродистая сталь, легированная сталь, нержавеющая сталь
• Ковкий чугун: For high-strength structural components
• Specialty Alloys: Tailored to project requirements

We also provide material selection guidance based on load, function, and environmental requirements.
