Green sand undergoes a "mulling" process in which water and clay act like binders, and are blended with sand resulting in a compound mixture which is suitable for the green sand molding process. The sand is rammed, compacted, and squeezed around a pattern by one of our green sand molding machines. Our green sand casting molding equipment
Historically, green sand consisted of silica sand, bentonite clay, water, and sea coal. However, sea coal is no longer commonly used today and has been replaced by other materials. While green sand casting remains in common use, "nobake," chemical set, or coldset processes are becoming predominant in today''s foundries.

Green sand casting for nonferrous metals does not use coal additives, since the CO created does not prevent oxidation. Green sand for aluminum typically uses olivine sand (a mixture of the minerals forsterite and fayalite, which is made by crushing dunite rock). The choice of sand has a lot to do with the temperature at which the metal is poured.
