Sand Casting

Sand casting is used to make large parts, suitable for Aluminum alloy, Iron, Steel and Brass metal. There are two techniques: green sand casting and resin sand casting. The sand cast molds are same for the two ways, their difference is only sand. Green sand is for green sand casting process, which is the most common used by foundries; resin sand is for resin sand casting process or making cores.

Sand casting is used to produce a wide variety of metal components with complex geometries. These parts 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, such as engine blocks, engine manifolds, cylinder heads, and transmission cases.

Sand casting is able to use of almost any alloy. An advantage of sand casting is the ability to cast materials with high melting temperatures, including steel, nickel, and titanium. The four most common materials that are used in sand casting are shown below, along with their melting temperatures

Materials              Melting temperature   
Aluminum alloys     1220 °F (660 °C)   
Brass alloys           1980 °F (1082 °C)   
Cast iron               1990-2300 °F (1088-1260 °C)   
Cast steel              2500 °F (1371 °C)   

INGBO RUICAN MACHINERY COMPANY cover different foundries and machining factories based on different casting process: investment casting, sand casting and pressure die casting, gravity casting, as well as precision machining with CNC machines.
