Brass Casting Foundry Serving the United States

Brass casting foundry core cleaning and finishing

Brass is chosen when you need corrosion resistance, clean machinability, and reliable performance in real-world conditions. The difference is working with a brass casting foundry that can hold the process steady so your parts fit, machine, and finish the way you expect.

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 Brass Casting Foundry” Means Here

One accountable supplier: casting, machining, inspection, and secondary operations coordinated under one roof.
Less rework downstream: controlled molding and pouring practices that help castings machine cleanly.
Fewer vendors to manage: one quote, one schedule, one team that owns the outcome.

Why Brass Gets Spec’d

Brass is commonly selected for components that live in corrosive environments or need stable performance over time.

Corrosion resistance for plumbing and moisture-exposed applications
Machinability for threaded features, sealing faces, and tight fits
Dimensional stability for repeat production parts
Clean finish potential for visible or customer-facing components

Brass Casting Processes Built Around Your Part

We help match the casting method to your geometry, tolerance expectations, and production needs.

Permanent Mold Brass Casting

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

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

Green Sand Brass Casting

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

Best for: production-friendly geometry, balanced cost, dependable output.

No-Bake (Air-Set) Brass Sand Casting

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

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

Precision Shell Sand Brass Casting

Superior finish and dimensional accuracy for small to medium 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.

Quality and Inspection That Protect Your Downstream Work

When brass parts are heading into plumbing, construction, or machined assemblies, rejects are expensive. Our Quality Assurance Plan is built to reduce rework with documented procedures and inspection support.

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 finished components, not just raw castings, we support ready-for-use 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 Brass Foundry Work We Support

Plumbing fittings, housings, valves, and connectors
Construction hardware and corrosion-exposed components
Machined brass castings that must hold critical dimensions
Projects that need a single supplier from tooling through finished part
