The pattern is made of wax, wood, plastic, or metal. The molds are constructed by several different processes dependent upon the type of foundry, metal to be poured, quantity of parts to be produced, size of the casting, and complexity of the casting. These mold processes include: Sand casting – Green or resin bonded sand mold.
For aluminum castings, sand casting represents about 12% of the total tonnage by weight (surpassed only by die casting at 57%, and semi-permanent and permanent mold at 19%; based on 2006 shipments).

Sand casting is one of the earliest forms of casting practiced due to the simplicity of materials involved. It still remains one of the cheapest ways to cast metal because of that same simplicity. Other methods of casting, such as those using shell molds, boast higher quality of surface finish but have a higher cost.
The process can be used for both small castings of a few ounces and large castings weighing several hundred pounds. However, it is most suitable for small parts at large volumes. [5] It can be more expensive than die casting or sand casting, but per-unit costs decrease with large volumes. Investment casting can produce complicated shapes that ...
