Cleaning comprises the essential process of removal of sand, scale, and excess metal from the casting. The procedure entails separating the casting from the mould and transporting it to the cleaning department, where, burned-on sand and scales are eradicated, improving the surface appearance of the casting. Excess metal, in the form of fins, wires, parting line fins, and gates, are also cleaned. Moreover, castings may be upgraded by welding or another procedure, following which, an inspection of the casting for defects and general quality is conducted.
