Brass, Bronze, and Aluminum Castings

Prototypes, short runs and high production. We use the latest technology and a best-in-class production control system to assure you of better parts for less money with the shortest possible lead times. We make it easy to do business with us.

Best In Class

Our vision is to be best in class in the market segments we serve. We want to be measured and recognized as the best by our customers, suppliers, employees and community.

Since 1869

We are experienced and we have been experienced for a long, long time. We are not just the oldest maker of brass, bronze, and aluminum sand castings, we are the oldest manufacturer of anything in the state of Minnesota.

Lean. Green. Not a Bit Mean.

We are lean practitioners. We continually strive to remove the waste from our process. We use the tools of lean to continually improve our processes and product. We are currently in a partnership with Enterprise Minnesota, The Minnesota Technical Assistance Partnership, The Minnesota Job Skills Partnership, The Minnesota Department of Economic Development and four other foundries to research and implement a concept called Lean Green 2.0.

Size Matters

Casting Sizes Poured:
        1 to 1500 lbs in brass and bronze
        1 to 600 lbs in aluminum.
Mold Sizes
        Up to 30X42 flask size in Green Sand
        Up to 4000 lbs Airset (No-Bake) Mold Sand Weight
That’s living large.

Shortest Lead Times in the Industry

If you have an order flow that qualifies for our kanban program, we can have parts to you the same day you release them. That’s zero days of leadtime.

For standard no core sand castings, if you get your order in by 2 p.m. Monday, we will ship them on Thursday of the following week. Truth is, we can do it faster if you need it. If your business model depends on fast turnaround to your customer we can help. Call us. If you want to partner to figure out how to get castings before you order them, we're in.

On Time Delivery.

Time is money. Because we control every step of our process with precision, we know how long it takes to get the parts to you. When we promise a delivery date we take that promise seriously. We do everything in our power to make it happen. And it does. Our customers consistently tell us we rank among the best of their suppliers in delivery performance.

ISO 9001:2008

We are registered to ISO 9001:2008 for the manufacture of brass, bronze and aluminum castings. We are TS 16949 and AS 9100/NADCAP compliant. Because we think we benefit as much as you do from Advanced Product Quality Planning (APQP) , we do PPAPs free of charge.

We’re Repetitive

Repeatability comes from doing each step of each process precisely the same way whether it is done daily or once a year. We have the most thoroughly documented production control system in the industry. That"s not bragging. That"s a fact.

Taking On the Toughest Challenges

Specializing in land and maritime military systems and complex, highly demanding, industrial castings. We serve over 100 NAICS codes. Our castings are used in a wide variety of applications including those requiring CE marking, NDT testing, sampling schedules, chemical and physical certifications, plating, polishing, or machining.

Impellers and Pumps

The highest quality manufacturer of double shroud, compound-curved-vane impellers in the country. Suction casings, volutes, discharge fittings - we know them and do them well. Smooth, accurate core processes form vane surfaces that result in higher head pressures and less cavitation, often without the usual secondary vane polishing operations. It just gets better and better.

Pressure Equipment

We make castings certified to the Pressure Equipment Directive (PED). Our parts bear the CE mark for export to Europe and the rest of the world. ISO 9001:2008 registration enables us and our customers to perform in process certification of pressure components. This eliminates the costly need to hire a notifying body to perform on site inspections.

Project Management

We have the systems and expertise to provide turnkey solutions for your project. We work with value-added partners for machined castings, polishing, plating, painting, powder coating, heat treatment, and assembly. We can provide one stop shopping or any intermediate level of completion that is appropriate for your project. We have well over a century of knowledge and experience in land and maritime weapons systems and platforms. Our foundry produces castings for some of the most advanced weapons systems in use by our armed forces today. ISO 9001:2008 certification prequalifies SPBA for DoD supplier approval.

Tough casting design? Bring it on.

We have the expertise and systems to turn your most difficult designs into high quality components. SPBA specializes in non-ferrous castings that require a little or a lot extra. Our abilities in extremely complex, difficult to cast bronze and aluminum castings carry over into all of our work. We bring value to help you be more profitable.

Continuous Improvement

Every day in every way we want to be better than we were before. If you have taken that approach you know it can be a struggle some days. we are not perfect, just seeking to be. We want to learn, grow, invest, change, and challenge ourselves. We are least comfortable with the status quo. Not changing makes us very uncomfortable.
