At Lincoln Foundry, there are no easy paths to producing a quality casting. It’s why we stick with the long, hard road where every mold, every pour, and every final grind is a measure of our commitment to workmanship and delivering a premium-quality product. Our sand-casting capabilities are grounded in proven high-demand alloy compositions, controlled finishing methods, and the rigorous in-house testing that verifies the integrity of the finished part.

Our bronze casting services specialize in producing components where high strength and wear resistance are critical. We cast a full range of alloys, from high-tensile manganese bronzes and lead-free formulations to nickel-aluminum bronzes for the most challenging marine environments. The versatility of these materials makes them the time-proven choice for parts such as industrial bushings, bearings, and naval hardware. The final product is a dense, rugged bronze component engineered to withstand continuous wear and corrosive environments.
We pour brass for components that must balance reliable performance with a clean, finished appearance. Our foundry casts parts from a range of alloys, including red brasses for general hardware to lead-free formulations for potable water compliance. This process creates dense, non-porous castings, making the material ideal for pressure-critical valves, fittings, and plumbing components. The result is a solid, leak-proof component built to provide decades of durable performance.
Our stainless steel castings are made for the most demanding operational environments. We produce components from both 304 and 316 grades that maintain their integrity under harsh chemical exposure and in sanitary applications. This material is ideal for parts requiring extreme durability and superior corrosion resistance. These alloys produce tough, non-corrosive castings that ensure reliability in critical systems.
Lincoln Foundry specializes in aluminum castings for applications where an excellent strength-to-weight ratio is the primary design goal. We cast specific alloys, including 319 and 356, to create lightweight parts that can be heat-treated to a T6 condition for significantly higher strength. This process is ideal for complex components in the aerospace and automotive industries. The final casting reduces mass without sacrificing the structural integrity required for its application.
Our foundry is equipped to handle a specific range of casting sizes and weights. This versatile operational capacity allows us to maintain the hands-on control necessary for smaller, complex jobs and to utilize techniques such as dual pot pouring for larger parts.
Lincoln Foundry specializes in delivering high-quality raw-cast or rough-cast components ready for your machining. We also offer shot-blasting and grinding services upon request. Additional services offered through trusted third-party providers are also available.
At Lincoln Foundry, our work meets strict compliance needs through a disciplined, hands-on process. We use certified materials, precise melt control, and rigorous testing to ensure metallurgical integrity. Every pour is documented and traceable to the foundryman who made it. That traceability ensures accountability and pride are cast into every part we produce.
All of our castings begin with certified raw ingots, backed by certificates of analysis that are available to customers upon request. Strict material-handling procedures prevent cross-contamination between alloys and are adhered to constantly throughout the facility. We verify mechanical properties using test bars pulled and analyzed in-house with modern equipment.
A successful casting begins with the pattern. This precise replica of the final part must be built to rigorous standards to ensure dimensional accuracy and casting quality. From the initial pattern development to the final pour of your production run, our expertise covers the entire sequence. Our pattern shop can work with your existing tooling or design and build new patterns from scratch based on your drawings.
We produce these patterns from a full range of materials, including wood, aluminum, plastics, and 3D-printed media, based on the final part specifications. Our team uses CAD/CAM and CNC technology to rig each pattern with the necessary gating and risers. The pattern is then mounted onto a board to create the final mold cavity in the foundry.
Our melt control relies on two 175 kW-1000 cycle electric induction furnaces and immersion pyrometers. The manufacturer periodically calibrates the pyrometers, and we keep all records on file. We guarantee a minimum of 85% I.A.C.S. conductivity in our pure copper castings, a standard we verify with calibrated meters on every heat.
Before any part leaves our foundry, we confirm its integrity through a combination of advanced metallurgical testing and hands-on inspection. Our SpectroLab verifies the chemical composition of every heat. Upon request, our in-house bar puller tests mechanical properties such as tensile yield strength, tensile strength, and elongation. This dual-verification process provides quantitative proof that your casting is both chemically and structurally sound.
This final review process covers two critical areas:
Visual Inspection: Our skilled team inspects each component for surface finish and integrity at multiple stages, from shakeout through the grinding and cleaning operations to final packaging. We check for any surface-level discontinuities, ensuring parts are free from cracks, pits, or shrinkage. This thorough visual check guarantees that the component meets both aesthetic and functional surface standards.
Mechanical Inspection: We verify raw components conform to the required dimensional tolerances specified in your drawings. Our team uses precision gauges, calipers, and other tools to confirm the accuracy of critical features. This step ensures that the as-cast component provides a reliable and accurate foundation for any subsequent machining or assembly.
