Bronze Casting Foundry Serving the United States

Bronze casting foundry pouring bronze

When the part has to last, carry load, resist wear, or run in harsh environments, bronze is often the right call. The difference is choosing a bronze casting foundry that can control the process and deliver parts that machine cleanly, fit correctly, and show up on schedule.

Buffalo Metal Casting has produced non-ferrous castings and finished components since 1975, supporting customers across the United States as a single-source supplier from pattern to shipped part.

What “Single-Source Bronze Foundry” Means Here

One accountable supplier: casting, machining, inspection, and secondary operations coordinated under one roof.
Parts that behave in machining: process control that helps reduce tool wear, scrap, and dimension drift.
Less vendor juggling: one quote, one schedule, one team that owns the outcome.

Bronze Casting Processes Built Around Your Part

Different geometries, tolerances, and volumes require different methods. We help match the casting process to your performance requirements and production needs.

Permanent Mold Bronze Casting

Reusable metal tooling for repeat production and consistent results across runs.

Best for: recurring parts, stable dimensions, long-term cost control.

Green Sand Bronze Casting

Cost-effective molding for small to medium bronze castings where practicality matters.

Best for: production-friendly geometry, balanced cost, durable parts.

No-Bake (Air-Set) Bronze Sand Casting

Reliable method for medium to larger bronze castings with improved finish and accuracy.

Best for: larger parts, complex cores, higher surface-finish expectations.

Precision Shell Sand Bronze Casting

Superior surface finish and dimensional accuracy for small to medium bronze castings.

Best for: tighter requirements, cleaner surfaces, fine detail.

Automated Flaskless Matchplate Molding

Automated green sand molding for repeatability and detailed production work.

Best for: repeat orders, consistent output, detailed features.

Capacity That Covers Prototypes Through Production

Whether you need a one-off prototype, a short production run, or recurring orders, we build the process around your part and your timeline. If you are unsure which method fits, send the print and we will recommend the best approach.

Quality and Inspection That Protect Your Downstream Work

Bronze parts are often used where failure is expensive. Our Quality Assurance Plan is built to reduce rework by defining procedures across departments, documenting inspections, and aligning to ISO-based expectations.

ISO-aligned quality planning with documented tests and inspections
Inspection and testing support for customer specifications
Non-destructive testing options: X-ray, penetrant, pressure testing
Physical and chemical analysis available when required

Value-Added Services That Turn a Casting Into a Finished Part

If you need a finished component, not a raw casting, we can support “ready for assembly” requirements with services that keep quality and timing under control.

Engineering assistance and casting layout support
Pattern-making and production tooling construction
In-house heat treating
CNC machining (vertical milling centers and lathe work)
Finishing: plating, painting
Heli-arc welding and assembly

Typical Bronze Foundry Work We Support

Bushings, bearings, wear plates, and friction components
Marine and corrosion-exposed components
Machined bronze castings that must hold critical dimensions
Projects that need a single supplier from tooling through finished part
