Welcome to Metalcasting Additives

Our Metalcasting Additives business unit is the key supplier of green molding sand additives to the global foundry industry.

Since the establishment of IKO Industriekohle in 1964 in Germany, we have earned a reputation for expertise, service, quality and innovation in this field. After our strategic combination with the Imerys group, the brand Imerys Metalcasting Solutions has emerged from the IKO brand.

Foundry Solutions Worldwide

We have a long tradition as a supplier of foundry-grade bentonite, originally using our world renowned reserves on the island of Milos. With the acquisition of IKO-Erbsloeh, we moved closer to foundry customers in Europe, supplying them with bentonite, coal and application technology. The group expanded into the Americas by incorporating the expertise, technology and assets of the Hill & Griffith and BPM foundry businesses.

Today the Imerys group offers foundry solutions worldwide out of its bases in Europe and America as well as through newly established joint ventures in Asia. Within the group, Imerys Metalcasting Solutions as a brand symbolizes the know-how, customized services and quality offered to this important market segment.

Innovation for the Foundry Industry

Our industry-leading technology has been instrumental in the development of a range of innovative products and solutions for many segments of the foundry industry, addressing environmental concerns associated with molding and core making.

From the ENVIBOND® System, which enables the foundry to operate with fewer emissions, to the patented RIKO® process, which utilizes the waste stream from green sand extraction systems as a source of materials for green sand molding operations, we are constantly searching for and developing new, sustainable answers to the industry’s ever-evolving challenges.
