The Sand Casting process -RuicanGreen Sand Mold process - is commonly used in the casting of aluminum, brass/bronze, and iron products.

The term "green sand" is known principally because of the moisture content within the sand. The sand undergoes a "mulling" process in which various clay and chemical additives that act as binders are blended with the sand, which results in a compound which is suitable for the sand molding process.
