Precision Patterns & Tooling

Built to Last. Designed for Flexibility.

At One-Off Castings, we manufacture high-performance aluminum patterns and tooling using our proprietary RoboCast process, enabling near-net castings that are finished in-house to exact tolerances. Our pattern-making services are engineered to support both long-term production and one-off casting needs — with quality, adaptability, and speed.

Why Choose Aluminum Patterns?

  • Long-Term Durability
    Unlike wood or plastic tooling, aluminum offers exceptional wear resistance — ideal for repeat use, dimensional stability, and prolonged service life.

  • Superior Accuracy
    Achieve tighter tolerances and smoother surface finishes for consistent, high-quality castings with reduced post-processing.

  • Design Modifications Made Easy
    Need to update a feature, add a logo, or revise a part number? Our aluminum tooling is designed with built-in flexibility for ongoing adjustments.

Engineered, Not Just Machined

We don’t just build tooling — we engineer it. Every pattern is optimized using solidification modeling and flow simulation software to minimize defects, improve metal fill, and extend tooling life. The result is a casting-ready solution that delivers repeatable, reliable performance — from the first pour to the hundredth.

Perfect for:

  • Repeat production runs with consistent quality demands

  • Near-net castings that require minimal machining

  • Long-life tooling for high-usage or multi-year programs

  • One-off or prototype tooling with potential future revisions

Tooling Options Available

We offer multiple tooling configurations to support a wide range of part geometries, foundry setups, and production volumes:

Cope & Drag Insert Patterns

Modular tooling designed for flexibility and reuse. Ideal for small- to mid-size runs requiring adaptable mold configurations.

Dedicated Patterns

Integrated systems where the flask and pattern are built as a single unit. Offers high stability and repeatability for recurring jobs.

Matchplate Tooling

Best suited for more complex geometries or higher-volume production. Ensures precise alignment and fast mold cycles in automated setups.

Our Tooling Process

RoboCast Pattern Creation

We begin by producing a near-net aluminum casting using our proprietary RoboCast process, built specifically for your tooling needs.

In-House CNC Machining

Each pattern is machined to final specifications using advanced CNC equipment—ensuring dimensional accuracy and surface finish consistency.
