Sand Casting Most widely used casting process Most sand casting operations use silica sand (Silicon Dioxide)mixed with some clay and water.It is inexpensive and suitable as a mold material. ■ Can work with nearly any metals;esp.the ones with high melting temp.(steel,nickel,titanium). Low tolerance/surface finish:need subsequent machining Shanghai Jiao Tong University 7Shanghai Jiao Tong University 7 Sand Casting n Most widely used casting process n Most sand casting operations use silica sand (Silicon Dioxide) mixed with some clay and water.
