Imerys molding sand additives represent state of the art technology and offer a number of specific benefits for green sand molding.

Molding processes based on bentonite bonded sand are of major importance in the field of sacrificial mold making. Along with providing for relatively low molding costs, a high level of sand reclamation and easy disposal of spent molding materials, bentonite bonded sand allows for the utilization of modern high pressure molding lines which enables high casting productivity. Our lustrous carbon formers, when added to bentonite bonded molding sands, provide additional advantages, minimizing sand adhesion to the casting and shakeout, as well as enhancing casting surfaces and reducing casting defects.
