Foundry operations started in 1984 as Novatec with 12,000 square feet of leased space in the back bay of the facility located on 845 Hickory Street in Pewaukee, WI. In 1988 Novatec was acquired by new investors and Northern Stainless Corporation was formed.The foundry changed hands one more time in 1991 when it was purchased by the current ownership. Since that time, continual reinvestment has allowed the business to grow to where it is today: an impressive 60,000 square foot state-of-the-art facility spread across two buildings and seven acres of land.

Quality American Foundry Casting Services
WI Steel Casting ManufactuerOur team of expert patternmakers, metallurgists, engineers, and foundry personnel produce metal castings up to one ton in size in a timely fashion, with assured excellence and at competitive prices.

While we’re primarily known as a metal casting foundry, our engineering team has capabilities beyond casting. We also manufacture prototypes or produce one-offs, including core printing. To save our customers time and money on the casting process, MAGMASOFT for solidification modeling. Our newly acquired Bruker-Magellan spectrometer provides chemical composition analysis including Nitrogen for super duplex stainless steel alloys. We also regularly employ liquid penetrant inspection (LPI) for product defect detection as well as pressure testing 100% of pressure containing rough castings to avoid any castings that could potentially leak from reaching our customer.

Stainless Steel Casting Products for Pump and Valve OEMs
Northern Stainless chiefly produces components for OEM pump manufacturers. Our casting professionals cast any part needed for the hydraulic end of pumps including volute cases, impellers and diffuser bowls. To ensure consistent hydraulic pump performance, we utilize several sand core mixtures for exceptional finishes. We also manufacture castings for valve OEMs, as well as non-pump products for the paper and mining industries. The majority of our products are rough castings which are ready for machining. We also supply finished machine castings when required by our customers.
