Brass, bronze or aluminum castings and cast plaques made in either green sand, chemically bonded, or permanent mold processes.  Prototypes, short runs and high production.  We use the latest technology and an amazing production control system to assure you of better parts for less money with the shortest lead times.  We make it easy to do business with us.  

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 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.

It just gets better and better. We make castings certified to the Pressure Equipment Directive (PED). Our parts bear the CE mark for export to Europe. ISO 9001:2000 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.

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 tell us we have the best on time delivery record of any foundry.  Plus our lead times are short.  Time is money.

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. 

We serve over 150 SIC 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, machining.

We have the expertise and systems to turn your most difficult designs into economical components.  SPBA specializes in non-ferrous castings that require that little extra.  Our expertise in extremely complex, difficult-to-cast bronze and aluminum impeller castings carries over into all of our work.  We help you be more profitable.

Commemorative bronze cast plaques preserve your message for posterity.  We have a special process to turn your project around fast, accurately and with more flexibility.  That's just what happens when you cross a six thousand year old process with lasers. 

Tilt pour permanent mold capabilities up to 24X36 mold size.

Aluminum is the fastest growing metal market.  It's strong, lightweight, attractive and doesn't rust.  We've been a leader in aluminum castings for as long as there have been aluminum castings. 

Bronze is used in a wealth of high stress applications and corrosive environments.  Bronze is visually appealing in its natural state, weathered or with patina applied. Our free casting design and alloy selection guide can help you choose the right one for your application.  With us you get age and beauty.  What a deal.
