Green sand moulding is  the most intimate component of the manufacturing process; so intimate, the surface of the casting truly replicates the mould itself. Dimensional integrity and aesthetics embrace the character of the mould in the manufacturing process. Challenge therefore is in creating the mould consistently every time  appreciating the thermal overloads the mould undergoes from hot metal.  

 
Green sand moulding affords reuse of spent and unspent sand for subsequent moulding, by simply recirculating and reprocessing it, entailing a small percentage to be discarded continually for stability. The sheer economy of this process has challenged expensive alternatives.
