Sand Casting

Sand casting, the most widely used casting process, utilizes expendable sand molds to form complex metal parts that can be made of nearly any alloy. Because the sand mold must be destroyed in order to remove the part, called the casting, sand casting typically has a low production rate.

  • Brass Sand Casting

    Brass sang casting, as the name suggests, involves the use of brass as the molten metal. Brass casting can be carried out by the way of brass sand casting only.
  • Grey Iron Casting

    The sand casting process involves the use of a furnace, metal, pattern, and sand mold. The metal is melted in the furnace and then ladled and poured into the cavity of the sand mold, which is formed by the pattern.
  • Ductile Iron Casting

    The sand casting process involves the use of a furnace, metal, pattern, and sand mold. The metal is melted in the furnace and then ladled and poured into the cavity of the sand mold, which is formed by the pattern.
  • Aluminum gravity casting

    Aluminum gravity casting and sand casting process is better to avoid porosity inside casting after secondary machining.
  • Aluminum Sand Casting

    Aluminum casting Process are classified as Ingot casting or Mould casting. During the first process, primary or secondary aluminium is cast into rolling ingot (slab), extrusion ingot (billet) and wire bar ingot which are subsequently transformed in semi- and finished products.
  • Green Sand Casting

    These molds are made of wet sands that are used to make the mold's shape. The name comes from the fact that wet sands are used in the molding process.
  • Lost Foam mould casting

    The lost foam casting process utilizes injection modeled polymeric foam patterns for the production of metallic components. Foamed polymer patterns of the desired shape are coated with a water-based refractory slurry, dried and embedded in unbonded sand.
  • Shell mold casting process

    Shell mold casting or shell molding is a metal casting process in manufacturing industry in which the mold is a thin hardened shell of sand and thermosetting resin binder backed up by some other material.
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)
