Precision in Motion: How One Off Castings Is Redefining Foundry Manufacturing with RoboMolding

The Rise of Smart Foundries

As industries demand more complex parts in smaller runs and shorter timelines, traditional casting methods just can’t keep up. That’s why at One Off Castings, we're embracing the future with RoboMolding—a fully automated, patternless casting process that turns your 3D CAD files into precise mold cavities with no tooling required.

This isn’t just innovation. It’s a manufacturing revolution.

What Is RoboMolding?

RoboMolding is a proprietary process that uses industrial robotic arms (like the ABB 6700 series) to carve high-precision sand molds directly from 3D CAD models. It completely removes the need for traditional pattern tooling, drastically cutting lead times and boosting complexity capabilities.

Benefits of RoboMolding:

  • Zero Pattern Tooling – Save weeks of production and thousands in costs.

  • Rapid Turnaround – Go from concept to cast in days.

  • High-Precision Geometry – Perfect for aerospace, defense, R&D, and prototyping.

  • CAD-to-Cast Workflow – Upload your SolidWorks, STEP, or IGES files and let us do the rest.

From CAD to Casting in a Matter of Hours

Here’s how the process flows:

  1. Upload your CAD file – Solid, watertight models required.

  2. Automated Sand Milling – Our robotic arms precisely machine sand to form the mold cavity.

  3. Metal Pouring – We pour your chosen material (aluminum, stainless, iron, steel).

  4. Quality Check – Our Faro Arm inspection systems ensure dimensional accuracy.

  5. Delivery – You get your custom one-off casting, fast and flawless.

Why It Matters for One-Off & Low-Volume Projects

Traditional foundries are built for mass production—requiring months of prep and expensive tooling. At One Off Castings, we specialize in the exact opposite.

Our low-volume, high-complexity model is built for:

  • Prototypes and R&D parts

  • Aerospace or defense components

  • Heritage parts and legacy castings

  • Industrial or automotive custom parts

  • Any job where agility and accuracy are key

Built on Decades of Foundry Innovation

Founded under Southern Cast Products, One Off Castings has over 40 years of expertise in advanced casting solutions. Our 45,000 sq. ft. facility includes:

  • 4 RoboMolders

  • Large-format 3D sand printers (80" x 40" x 40")

  • Thermal sand reclamation

  • Heat treatment ovens for T-6 and stress relief

  • Faro Arms and CMMs for inspection

  • Full metallurgy lab for composition and tensile testing

When precision matters, we deliver castings engineered to perform.
