About Us


Founded in 1987, Tuson is a family owned and operated American company that manufactures and supplies precision-machined components, assemblies, and systems primarily made from metals. Typical of these are steel, ductile iron, aluminum, and copper. Tuson supplies its products to a variety of OEMs in several industries. Those business segments include fluid power, electric motors and linear actuators, mobile hydraulic equipment and machinery, industrial (stationary) machinery and equipment, recreational vehicles (RVs), and many others.

Since inception, we have grown from a one-man operation into a global company with over 330,000 sq. ft. (> 30,650 sq. m.) of operating floor space that is home to more than 400 employees. Our facilities in China, Taiwan, Japan, and the USA utilize state-of-the-art technology and equipment. We possess over 360 manufacturing machines to fulfill the needs of our customers. We offer a variety of services including machining, grinding, finishing, polishing, inspection, assembly, and test. Our goal is to provide products that are always ready “out of the box” when they arrive at your dock. We work with our customers to help them design products that are both cost-effective and high-quality. One of the tools we use is DFMA (Design for Manufacturability and Assembly).

From our headquarters and inventory facility in Vernon Hills, Illinois, USA (near Chicago), and Tuson Manufacturing Company in Story City, Iowa, USA (near Des Moines), we offer manufacturing, testing and assembly services, stocking, and sales, service, and support. If long lead times are an issue for you, we can provide individually-tailored customer inventory management programs. Whether your company prefers VMI, EDI, Kanban, blanket orders, or other material management methods, we have experience with all of them. And, our track record includes 99%+ on-time delivery after initial production ramp-up.

Tuson takes pride in its product quality and capabilities. We hold the latest quality certifications (ISO 9001:2015 and IATF 16949:2016). These ensure we provide quality products and appropriate documentation, from initial prototypes through on-going series production. And, our company has a culture of continuous improvement. Our technology, processes, and people are constantly evaluated and improved to increase quality, efficiency, and value. For Tuson, continuous improvement is a never-ending journey.

Please give us a call or send us a message today. We’d like to hear about your needs!

“Our mission is to win the trust and loyalty of our customers with products and services of unrivaled quality and value.”
