lost foam casting
Lost foam casting is a metal fabrication process where a detailed foam model of the part is coated in a ceramic material. When metal is poured into the mold, the foam evaporates and turns to gas, leaving a hollow cavity in the shape of the original foam. The molten metal fills this cavity, producing a precise metal casting of the foam pattern. This method allows for complex, detailed metal parts with good surface finish and dimensional accuracy, often used in industries like automotive and aerospace manufacturing.
