Whether in terms of producing molded parts which are under one pound or metal parts weighing thousands of pounds, sand casting process is the preferred casting process. Due to the low cost of mold, sand casting process has many uses and can generate high returns, even in the case that the yield is low. Sand casting process can be used to manufacture castings with beautiful appearance and compliant core. Almost any metal alloy can be cast by sand casting process.
2. Advantages of sand casting process
Sand casting process is one of the few casting processes available for metals with high melting point such as steel, nickel and titanium. Sand casting process is currently the most widely used casting process because of its good flexibility, good heat resistance, and relatively low cost.
