Our Expertise

Alt_Text

The process of melting metal and pouring castings has a long tradition, dating back at least 5,000 years. Today, molds made from sand, ceramic or metal are widely used to cast precision parts for the automotive, aerospace, agriculture and many other industrial equipment manufacturing sectors. Imerys supplies the foundry industry with high-performance minerals and innovative solutions for molds and cores in sand casting and investment, as well as refractory solutions for both ferrous and non-ferrous foundries.

A wide range of high performance minerals, from bentonite to various types of refractory sands and flours, are used in the foundry molding process to improve casting accuracy and productivity. We are a  leading supplier of green molding sand additives for sand casting, as well as sintered and fused minerals for ceramic molding.  We are also the world’s leading producer of calcined products for the refractory industry.

The right technical solution to match each application

In an industry focused on quality and productivity, finding the right technical solutions to match each application is key. Our foundry solutions meet stringent specifications in terms of mold stability, thermo-mechanical properties and flexibility whatever the casting process. We also develop low-emission additives and recycling solutions that address sustainability issues and reduce total ownership costs for the foundry.
