A Sprayed Steel Tool for Permanent Mold Casting of Aluminum

A new application of steel sprayed tooling for the manufacture of prototype permanent molds for aluminum casting is discussed in this paper. The prototype tooling is quickly made by spraying onto substrates that define the tooling shell shape. The shell material, structure, and geometry are adequate to withstand, for a limited number of pours, the demands placed on an aluminum permanent mold. An initial demonstration shows the promise of this method.
