Products & Services
Unimin offers North America’s most extensive portfolio of high purity core and molding sands. INCAST® silica grades range from GFN 25 for lost foam backing to GFN 125 for non-ferrous molding. These engineered foundry sands are characterized by their low total surface area and uniform PSD, providing the ideal conditions to maximize tensile strength while reducing resin, catalyst and additive consumption.
Technical service is provided by application-focused customer teams. Their training is industry specific; with emphasis on the function and performance of our foundry sands in resin bonded core and molding processes, green sand and lost foam backing. With hands-on experience these teams facilitate the technical exchange that can help our customers improve productivity and yield, minimize emissions and waste, and create a sustainable competitive advantage.
