Green Sand Casting Process

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.

Place a metal or wood frame (flask) over the pattern to produce a cavity representing one half of the casting, compact or ram the sand to achieve the mold.
