This article explores the process, benefits, and applications of lost foam casting, showcasing why Kewei is the trusted partner for cutting-edge foundry solutions.

What is Lost Foam Casting?
Lost foam casting is an innovative casting process where an expendable polystyrene foam pattern is used to form a mold. The foam pattern is coated with refractory material, surrounded by sand, and vaporized during metal pouring, creating a precise cavity for casting.
This method is favored for its ability to produce intricate and high-quality components with minimal finishing, making it a popular choice across various industries.
How Does Kewei Lost Foam Casting Work?
Our integrates advanced technology to streamline the process:
- Pattern Production: Foam patterns are created using precision molding equipment for consistent quality.
- Coating Application: Patterns are coated with a refractory material to ensure smooth surface finishing and prevent metal defects.
- Compaction and Molding: Coated patterns are placed in a mold box filled with unbonded sand, which is compacted around the pattern for stability.
- Metal Pouring and Casting: When molten metal is poured, the foam pattern vaporizes, forming the desired casting shape with exceptional detail.
