Steel Sand and Investment Castings

Sand casting, also known as sand molded casting, is a metal casting process that uses sand and binder as the mold material. A steel sand casting is produced by placing a pattern (tooling) with a gating system in sand to create a mold. The pattern is then removed and liquid molten steel is poured into the mold cavity. Once the metal cools, the sand mold is broken away from the part and the casting is cleaned. Steel sand castings can be from around 1 lb. to 1,000,000 lbs, and with various degrees of complicated configurations.

Investment casting, also known as lost-wax casting, is an old technique for forming metal. The technique is often used for small castings but can produce steel castings of up to 600 lbs and aluminum castings of up to 60 lbs. In investment casting, a ceramic mold is made from wax patterns. After the wax is removed from the mold and it is preheated and sintered, molten steel is poured in the mold to form the casting. The investment casting process usually costs more per unit than die casting or sand casting but has lower equipment costs. It can create intricate shapes that would be difficult at best with die casting yet it requires little surface finishing and minor machining in some cases. Finally, we can make castings from aluminum and iron as well.
