We have more than 40 years’ experience in processing, blending, and supplying combinations of our high-quality bentonite binders and lustrous carbon formers to the global foundry industry. Our blends also include treated carbon and lustrous carbon formers to improve casting surface quality, optimize molding sand performance, and minimize additions. In addition to keeping molding costs relatively low with a high level of sand recovery and easy disposal of spent molding materials, bentonite bonded sand allows for the use of modern high-pressure molding lines, which boosts productivity. Our solutions include: bentonite, bespoke bentonite mixtures, slag additives, and protective coatings.
