About Us





Product confidence rides on every individual part used to make today’s machines, vehicles, combines, and durable goods. Confidence depends on durability, quality, and consistency. At Waupaca Foundry, we take pride in producing best-in-class gray iron, ductile iron and compacted graphite iron castings.

Using vertical green sand molding at all of our foundries, our casting process and technologies combine generations of people who say they have “foundry in their blood” with metallurgists who are compelled to improve castings and how they're made.


Our team has the pride that comes from making something that lasts. And we have a mindset that compels us to protect the natural resources of our environment because this is our future.


We invite you to learn more about Waupaca Foundry, the leading iron castings manufacturer in the industry, and how our quality, consistency and service help you and your customers excel.​​
