<P> Plaster mold casting is a metalworking casting process similar to sand casting except the molding material is plaster of Paris instead of sand . Like sand casting , plaster mold casting is an expendable mold process , however it can only be used with non-ferrous materials . It is used for castings as small as 30 g ( 1 oz ) to as large as 45 kg ( 99 lb ) . Generally , the form takes less than a week to prepare . Production rates of 1 -- 10 units / hr can be achieved with plaster molds . </P>
