Skin Dried Molds: When sand casting a part by the skin dried mold process a green sand mold is employed, and its mold cavity surface is dried to a depth of .5 1 inch. Drying is a part of the manufacturing process and is accomplished by use of torches, heating lamps or some other means, such as drying it in air.
