Supreme Cores was founded in 1978 in Janesville, Wisconsin to serve the needs of the foundry industry in Wisconsin, Minnesota, Illinois and Indiana. We produce foundry sand cores and molds to our customers’ specifications. A sand core consists of a mixture of sand and resin that, once cured, is placed in a mold to provide openings or shape to a metal casting.

Supreme Cores, Inc. has built its reputation by setting high goals for the quality and service we provide our Customers. As we continue our success we look for employees who possess the same focus on hard work and quality service as we have provided our customers over the last thirty-eight years.
