Sand casting refers to a casting method in which castings are produced in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting methods. Because the molding materials used in sand casting are cheap and easy to obtain, and the molds are easy to manufacture, they can adapt to single-piece production, batch production and mass production of castings. For a long time, it has been the basic process in casting production.
Sand casting is the most popular and simplest type of casting that has been used for centuries. Sand casting is used to make large parts such as gray cast iron, ductile iron, stainless steel and other types of steel. The main steps include drawing, mold, core making, modeling, melting and pouring, cleaning, etc.
The brief production process for sand casting as below:
Process design→Tooling design→Coremaking→Mould assembling→Melting and pouring→Mould opening→Cutting→Shot blasting→Grinding→Heat treatment→Shot blasting→Inspectation→Machining→Inspectation&Packing
