The Green Sand Process Vulcan Engineering Company

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 casting quality ...
