View Details & Specs →From Blueprint to Custom Castings.
A traceable, scientifically controlled custom sand casting process guarantees repeatability and precision across thousands of industrial parts.
1. Tooling & Pattern
In-house CAD/CAM pattern making using high-grade materials for dimensional accuracy before the first pour.
2. Automated Molding
Advanced resin sand systems ensure highly stable mold cavities capable of handling complex geometries.
3. Precision Pouring
Spectrometer-verified molten metal is poured under strict thermal control to guarantee metallurgical integrity.
4. Finishing & Heat Treat
Shot blasting, grinding, and custom thermal cycles to achieve your specific mechanical yield requirements.
In-House CNC Machined Castings.
We deliver Ready-To-Assemble (RTA) components directly from our sand casting foundry. By casting and CNC machining under one roof, we eliminate supply chain delays and take full responsibility for the final tolerances of your custom parts.
- State-of-the-art 5-Axis Milling & Turning Centers
- Tight tolerances for critical bores, keyways, and mating surfaces
- Comprehensive Chemical Analysis & CMM Inspection
We Make Importing Industrial Castings Easy.
Worried about freight, customs, or damaged heavy castings? Don’t be. We securely ship thousands of tons of metal components to the US and Canada annually.
Trusted by North American B2B Buyers.
“Kurt Foundry significantly reduced our lead times for 2-ton cast iron counterweights. Their ability to handle the precision CNC machining in-house saves us a massive logistical headache.”
“We shifted our custom ductile iron flywheel production to Kurt last year. The metallurgical reports always strictly match ASTM standards, and their communication is top-notch.”
“Finding a sand casting foundry that can pour large motor housings without porosity issues is tough. Kurt Foundry nailed the custom prototype on the first try.”
Foundry Frequently Asked Questions
We specialize in both medium and high-volume production of industrial metal castings. While it depends on the part’s size, our typical MOQ starts at 1 Ton per order to ensure setup efficiency and cost-effectiveness.
Tooling and pattern development typically takes 3 to 4 weeks. Once the initial sample is approved by your engineering team, bulk foundry production requires approximately 4 to 6 weeks, depending on machining requirements.
Absolutely. As an ISO 9001 certified sand casting foundry, we provide full material test reports (MTRs) including chemical composition (via spectrometer) and mechanical properties for every batch poured.
