What Are Custom Lost Foam Molds?

Custom lost foam molds are an exceptionally efficient casting technique that utilizes a foam pattern, which is coated with a refractory material. Once set, the pattern is heated, causing it to vaporize and leave a cavity that is then filled with molten metal. This approach allows for complex shapes and intricate details that are difficult to achieve with traditional molding methods.
