The Ermak shop floor in Chaska, Minnesota

Our story

Built on long relationships.

Ermak was built by Jeff and Sue Erickson into a foundry and machine shop known for quality work, on-time delivery and doing whatever it takes for customers. Some of those customers have bought from Ermak for more than fifty years.

In 2017 Reg Zeller bought Ermak, drawn by its reputation and its people. In 2019 Ermak brought in Northwest Casting of St. Paul, combining two experienced teams and their equipment under one roof in Chaska.

Ermak was the first plant in what became CaneKast, a network of American non-ferrous foundries that now includes Patriot Foundry in New Hampshire and Southern Aluminum Foundry in South Carolina.
