Sand Casting Foundry Serving the United States

Sand casting foundry pouring molten metal

Sand casting is the workhorse process when your part needs flexibility in geometry, size, and tooling cost, without sacrificing function. The difference is partnering with a sand casting foundry that can control the variables that cause porosity, scrap, and dimension drift.

Buffalo Metal Casting produces non-ferrous castings and finished components for customers across the United States as a single-source supplier from pattern to shipped part.

Sand Casting Processes We Use

Different run sizes and requirements call for different sand molding methods. We help match the process to your tolerances, finish needs, and tooling goals.

Green Sand Casting

Cost-effective molding for repeat parts and production-friendly geometry.

Best for: small to medium castings, balanced cost, repeatability.

Learn about Green Sand Casting

No-Bake (Air-Set) Sand Casting

Strong option for larger or more complex castings with improved surface finish vs typical green sand.

Best for: larger parts, complex cores, higher finish targets.

Learn about No-Bake Sand Casting

Precision Shell Sand Casting

Higher accuracy and a cleaner finish for small to medium castings.

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

Learn about Precision Shell Sand Casting

Aluminum Sand Casting

A frequent spec for lightweight parts that need corrosion resistance and strong value at scale.

Best for: structural components, housings, covers, and machined castings.

Materials That Fit Sand Casting Well

Sand casting is widely used across non-ferrous metals because it supports flexible geometry, cored designs, and practical tooling costs.

Aluminum: lightweight, corrosion-resistant, versatile across industries
Brass: corrosion resistance and machinability for fittings, housings, and hardware
Bronze: wear resistance and durability for harsh environments and bearing surfaces
Copper: conductivity and corrosion resistance for electrical and thermal applications
Zinc-aluminum: strong detail and repeatability when spec requires it

Quality and Inspection That Protect Your Downstream Work

Most casting headaches show up later, during machining, assembly, pressure testing, or final inspection. Our quality approach is designed to reduce those surprises by documenting checks and aligning inspections to how the part will be used.

Documented quality planning and defined inspection points
Inspection support for customer specs and critical dimensions
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, this is where schedules get won or lost. We support “ready for assembly” needs 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: anodizing, plating, painting
Heli-arc welding and assembly

Typical Sand Casting Work We Support

Housings, covers, brackets, and structural components
Cored parts with internal passages or complex geometry
Machined castings that must hit critical dimensions
Projects that need a single supplier from tooling through finished component
