The sand casting process is used typically for larger parts and for small quantities of parts. Sand casting is capable of making fairly complex shapes using relatively inexpensive wood patterns. Sand and containing a natural or synthetic binder, is packed around a wood pattern, the sand is then tamped down to provide the two-part mold with adequate strength. The pattern is then removed, leaving a negative form in the mold. Wooden models are used as material for the casting pattern at a relatively low cost. Due to relatively low tooling costs the casting method can be used for prototype manufacturing. The surface finish and casting tolerances are adequate for most purposes.

Casting products can vary greatly in size and weight, ranging from a couple ounces to several tons. Some smaller sand cast parts include components as gears, pulleys, crankshafts, connecting rods, and propellers. Larger applications include housings for large equipment and heavy machine bases. Sand casting is also common in producing automobile components, Marine products, Pump and Valve components, engine blocks, engine manifolds, Cylinder heads, and transmission parts.
