1. The complex valve blank manufacturing and inspection process. Valve castings are formed by heating metals to thousands of degrees Fahrenheit, at which point they melt into liquids. The liquid metals are poured into molds, where they cool and take the shape of a specified valve. Valve cast blanks are structurally complex, thin-walled shell parts.
