Lost foam casting (LFC) is an advanced metal casting method using an expanded polystyrene (EPS) foam pattern that replicates the final part, which is coated in ceramic, buried in sand, and vaporized by molten metal when poured, creating intricate, precise parts without cores or parting lines. It's popular for automotive components like engine blocks due to its ability to produce complex shapes with excellent surface finish, reduced machining, and fewer steps than traditional methods, using unbonded sand for efficiency.
