What metals can be poured as a Lost Foam Casting?
Generally, all ferrous and non-ferrous materials can be cast using the Lost Foam Casting process. Metal pouring temperatures of at least 1000 degrees F are usually required to decompose the foam patterns and gating system. Advanced Cast Products pours all grades of ductile and austempered ductile (ADI) in lost foam. 3. What size range of parts can be produced by the Lost Foam Casting process? Lost Foam castings can be produced in weights ranging from < 1 pound to thousands of pounds. The Evapcast Division produces castings weighing as much as 100#, although the majority are less than 50 pounds. 4. What "as-cast" tolerances can I expect? Casting tolerances will vary depending on the size, complexity, and geometry of the part. Generally speaking, you can expect to achieve tolerances equal to or better than shell molded and permanent mold castings. Significant improvement over sand casting tolerances is possible. Subsequent coining or straightening procedures often enable even tighter tol
