Application Field of Lost Foam Casting

Jun. 14, 2024

Lost foam casting is an innovative and highly efficient casting process used in various industries. It involves creating a foam pattern, which is then coated with a refractory material and surrounded by sand. When molten metal is poured into the mold, the foam evaporates, leaving behind a precise metal casting. This technique is appreciated for its ability to produce complex and precise components with minimal finishing work. Let's explore the application fields where lost foam casting excels.
