High-Performance OEM Sand Casting Foundry Solutions
The Federal Group USA provides high-precision sand casting manufacturing services designed to reduce production lead times and tooling costs for global procurement partners. Operating with over 40 years of metallurgical experience, we specialize in high-integrity ferrous and non-ferrous cast components engineered to withstand extreme industrial operations.
From prototype molds to high-volume automated production runs, our ISO 9001:2015 certified quality control management system ensures every casting strictly satisfies your design tolerances, material grade specifications, and surface finish requirements.
Comprehensive Sand Molding Capabilities
We leverage multiple specialized molding techniques to align with your production volume, geometric complexity, and surface roughness targets.
Green Sand Molding
Cost-effective automated high-volume molding utilizing natural clay and water binders. Ideal for medium-to-large production runs of iron and aluminum components.
Resin Sand / Shell Molding
Combines high-grade quartz sand with synthetic resin binders for superior dimensional accuracy, fine detail reproduction, and enhanced surface finish.
Air-Set / No-Bake Molding
Employs room-temperature chemical binding agents for large, thick-walled, heavy-duty structural cast parts up to 30,000 lbs without heat application.
Rapid Prototype Tooling
Integration of 3D printed sand molds and pattern tooling to rapidly accelerate sample validation and reduce initial product development lead time.
Diverse Alloy Selection & Certified Metallurgical Testing
Selecting the optimal alloy is vital for ensuring mechanical strength, corrosion resistance, and thermal fatigue endurance. Our foundry facility executes precise chemical spectrum analysis and thermal processing to meet rigorous international standards (ASTM, ISO, DIN, JIS).
Ferrous Metals
Ductile Iron (60-40-18, 65-45-12, 80-55-06), Gray Iron (Class 30, 35, 40), Carbon Steel, Alloy Steel, Stainless Steel (304, 316, Duplex 2205/2507, Zeron 100).
Non-Ferrous Metals
Aluminum Alloys (A356, 319, 535), Brass, Manganese Bronze, Aluminum Bronze, Copper-Nickel, and Lightweight Magnesium Alloys.
