lost foam casting service for custom metal casting

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, and industrial equipment, with guaranteed dimensional accuracy, excellent surface finish, and consistent quality.

What is Lost Foam Casting?

Lost foam casting, 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: Steel, aluminum, ダクタイル鋳鉄, 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:

Pattern Design & Fabrication – Precision foam patterns based on CAD models, optimized for minimal defects and metal usage
Pattern Assembly & コーティング – Foam patterns assembled and coated with refractory material for surface quality and thermal resistance
Molding – Patterns placed in dry sand molds, compacted to maintain dimensional stability
鋳造 – Molten metal poured, foam pattern vaporizes, leaving near-net-shape casting
Cleaning & 熱処理 – Sand removal, 熱処理, and machining as required
品質保証 – Dimensional inspection, 硬さ試験, 金属組織分析

This process enables production of high-quality steel, ダクタイル鋳鉄, and aluminum components with excellent repeatability and surface finish.
