Taking On the Toughest Challenges

Specializing in complex, highly-demanding, industrial castings and castings for land and maritime military systems. We use 3D solid models which we input into our flow and solidification simulation software to predict and eliminate defects before we build a tool.  We serve over 100 NAICS codes. Our castings are used in a wide variety of applications including those requiring X-Rays, Pressure Testing, Penetrant Testing, CE marking, NDT testing, sampling schedules, chemical and physical certifications, plating, polishing, or machining. We have two spectrometers for redundancy. We check chemistry of every batch of metal before we pour. We do PPAPs. We use our FaroArm for FAI and have laser scanning for model matching.

Pressure Equipment

We make castings that meet the requirements of the Pressure Equipment Directive (PED). Our parts are critical components in machines and assemblies that bear the CE mark for export to Europe and the rest of the world. AS9100D(2016)/ISO 9001:2015 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.

Supply Chain Management

We simplify supply chain management for you. 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. AS9100D(2016)/ISO 9001:2015 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.
