Raw sand is mined and then processed to give it a consistent distribution of grain sizing. What Is a Steel Casting? Casting Process Fig. 1-2 Typical steps involved in making a casting from a green sand mold Molding Processes The Molding Processes are discussed in detail in Chapter 13. Green sand molding is the most widely used system and due to mechanization in many green sand foundries, the least expensive process. Water and clay in the sand allows molds to be produced
Foundries that are interested in using their spent foundry sand can consult the American Foundry Society guide, Turning Used Foundry Sand into a Marketable Resource: Best Management Practices for Beneficial Reuse. This guide explains how to start a recycling program, lists sand end users' general
Before 1900, American-made bronzes were produced in the French sand-casting method. This method, through which a sculpture is produced using a firm sand mold, was simpler than the ancient process of lost-wax (or cire perdu) casting and especially efficient for the production of utilitarian objects. By 1900, Roman Bronze Works specialized in the ...
