We have been producing a reputation for Quality, Reliability, and Service since 1936.
Prospect Foundry was founded in 1936 by two brother’s Michael and Peter Sitarz. They were former iron casting molders with the William Brothers Boiler Manufacturing Company – a small gray iron foundry producing industrial parts including fire ports and grates. Prospect’s initial foundry facility was located near Prospect Park in southeast Minneapolis, Minnesota.
In the early 1950’s, the company expanded its focus and began manufacturing complex ductile iron castings for a variety of applications in the construction, mining, and industrial markets. During the subsequent years, Prospect began to establish its reputation as a high quality, reliable manufacturer of complex iron castings in low-to-medium volumes. By continuing its focus on developing technical design capabilities, flexible manufacturing, product quality, and reliable service, Prospect developed long-standing relationships with its major customers.
We are proud to be Family Owned & American Made!
