Foundry & Casting Bentonite for Green Sand Casting

SEPIOFIN supplies high-performance foundry bentonite for green sand casting applications. Our Sepiocast-ECO and Sepiocast-MAX grades are designed to provide reliable mould strength, sand stability, thermal resistance and consistent casting performance.

Sepiocast-ECO

SEPIOCAST Eco , is a foundry grade, natural sodium bentonite optimized with high pressure activation for improved performance. Our medium-high swelling bentonite helps reduce sand loss during shakeout while providing easier stripping, making it ideally suited for high-volume foundries producing small castings.

Sepiocast-Max

SEPIOCAST Max is an activated sodium bentonite developed for green molding sand applications. It is particularly effective in the production of heavy and complex geometry parts with low sand-to-metal ratios, providing a solution for foundries by reducing molding issues and sand-related casting defects. Thanks to its high thermal resistance, it requires less consumption and ensures more efficient performance in the casting process.

Foundry Bentonite for Industrial Casting
Choosing the right foundry bentonite is essential for maintaining mould strength, sand system stability and casting quality. SEPIOFIN provides mineral solutions for foundries seeking consistent performance, efficient bentonite consumption and reliable supply.
