Pattern Building & Tooling Production
Most bad castings start with bad tooling. Don't let yours be one of them.
Casting quality begins with the tooling. A poorly engineered pattern can build dimensional variation, core shift, excess finishing, scrap and production delays into every mold. Once production begins, those mistakes multiply.
Don't let inexpensive tooling become the most expensive decision in your casting program.
Through our sister company, Spartan Pattern, Anderson Foundries brings pattern engineering, simulation and production together under one coordinated team. Our experts understand how a pattern must perform inside the foundry — not merely how it should look on a computer screen.
Built Right Before the First Pour
Our pattern and tooling capabilities include:
- Casting-focused pattern design and engineering
- MAGMA casting simulation
- Pattern building and core-box production
- Precision CNC machining
- ExOne 3D sand-printed molds and cores
- Pattern repair, modification and recreation
ExOne 3D Sand Printing
Our ExOne 3D sand printing technology allows us to produce complex molds and cores without traditional tooling, accelerating prototyping and helping prove challenging designs before investing in permanent patterns.
Real Tooling. Real Results.
As a new company, finding reliable suppliers is crucial, and Spartan Pattern exceeded our expectations in every way.
