Our market leadership in Foundry stems from these core points:

Focus on Innovation

Continuously working on new concepts to optimise costs and performance in your production of castings, our highly skilled engineers, with their well-established network of OEMs and end customers, quickly react to the ever increasing demands including (but not limited to) energy and environmental requirements and regulations.

Ideas and best practices are exchanged on a daily basis, allowing us to provide you an unparalleled level of reactivity and flexibility when handling local or international projects.

Our unique model of Quarry to Furnace

Owning a quartzite mine in Sweden gives us complete process control for our silica-based product range, ensuring for you high reliability and quality. Thanks to our parent company Imerys, Calderys also has secure and consistent access to other key raw materials vital for refractories in Foundry.
