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.
The quality of bentonite bonded molding sand is determined by its molding, casting and reclamation behavior. Molding sand additives from Imerys offer high and consistent quality combined with long term availability through our effective resource management.
Our ENVIBOND® and RIKO® technologies provide our customers with methods of increasing sustainability without sacrificing quality.
