Enduring Businesses

Dakota Foundry is a South Dakota-based manufacturer specializing in high-quality, 100% American-made ductile and gray iron castings for industries such as agriculture, construction, fitness, and heavy machinery. With a reputation for precision, consistency, and the fastest turnaround in the industry, Dakota Foundry combines traditional cupola melting with modern patternmaking, machining, and engineering capabilities to deliver critical components that meet exact customer specifications. Their vertically integrated model—bolstered by sister company Spartan Pattern—ensures complete control from pattern design to final casting, enabling rapid customization and uncompromising quality. Unlike offshore or “mail order” foundries, Dakota Foundry offers hands-on customer service, traceability, and domestic reliability with every order. Their clients range from local fabricators to national brands seeking dependable, short-run, or custom iron solutions—including premium fitness equipment components like kettlebells and barbells. Founded in 1977 and now part of Anderson Industries, the company also invests in the future of American manufacturing by funding the Iron Warrior Academy, a nonprofit that trains the next generation of welders, machinists, and foundry workers. Through expert craftsmanship, rapid fulfillment, and values-driven operations, Dakota Foundry delivers more than castings—they forge long-term partnerships built on trust, performance, and American pride.
