    The Green Sand Molding Process The term Green Sand denotes the presence of moisture in molding sand and indicates that the mold is not baked or dried Raw sand is mined and then processed to give it a consistent distribution of grain sizing When processed for molding, organic clays are added to bond the grains together A coal dust (known as Sea Coal) is added to control castingThe green sand for the casting molds usually has a mixture of: Sand = 7585% Bentonite Clay = 511% Water = 24% Other materials = 35% Silica in the sand can become airborne in the process of casting so American foundries install air control systems that pull the silica particles and anything else out of the air to keep foundry workers safe What Happens to the Sand After CastingWhat are Green Sand Castings? Willman IndustriesDuring casting, some of the components of the sand mixture are lost in the thermal casting process Green sand can be reused after adjusting its composition to replenish the lost moisture and additives The pattern itself can be reused indefinitely to produce new sand molds The sand molding processSand casting Wikipedia
