Sand Casting Process: How It Works

Pattern Creation

We create or refine patterns based on your CAD files or drawings, optimizing for casting performance.

Mold Preparation

High-quality casting sand is packed around the pattern to create a precise mold cavity.

Metal Pouring

Molten metal is carefully poured into the sand mold at controlled temperatures for optimal flow and solidification.

Cooling & Shakeout

The casting cools in the mold, then the sand is removed to reveal your finished component.

Finishing & Inspection

Parts are cleaned, machined as needed, and thoroughly inspected to your specifications.

Frequently Asked Questions

What types of casting sand do you use?

We utilize both green sand (clay-bonded) and chemically-bonded resin sand systems depending on the application. Green sand is ideal for high-volume production, while resin-bonded sand offers superior surface finish and dimensional accuracy for complex parts.

What's the minimum order quantity for sand casting?

We accommodate projects of all sizes—from single prototype castings to production runs of thousands of parts. There's no strict minimum order quantity.

How does sand casting compare to other casting methods?

Sand casting offers the most design flexibility and lowest tooling costs, making it ideal for large parts, complex geometries, and low-to-medium volume production. It's more cost-effective than investment casting or die casting for larger components.

What tolerances can you achieve with sand casting?

Standard sand casting tolerances are typically ±0.030" to ±0.060" depending on size. Tighter tolerances can be achieved through machining and specialized molding techniques.

What is the typical lead time for sand castings?

Prototype castings: 2-4 weeks. Production runs: 4-8 weeks depending on complexity and quantity. Rush services available.

Do you offer design assistance?

Yes! Our engineering team provides Design for Manufacturability (DFM) reviews, material selection guidance, and cost optimization recommendations.
