Terhorst Manufacturing has a rich legacy of innovation and engineering excellence dating back to 1926, when three Terhorst brothers relocated from Wisconsin with their physician father to establish a machine shop dedicated to manufacturing wind-powered energy systems of their own design. Combining mechanical and electrical engineering expertise, the brothers developed and produced wind-generated power plants that served the growing energy needs of rural communities. As rural electrification expanded across the United States following World War II, demand for wind-powered systems declined, prompting the company to adapt and evolve. Drawing on its strong foundation in precision machining, toolmaking, and engineering, Terhorst Manufacturing successfully transitioned to meet the changing needs of the industrial marketplace. In the early 1960s, recognizing the rapid growth of the plastics industry, Terhorst Manufacturing expanded its capabilities by entering the injection molding sector. This strategic evolution marked the beginning of a new chapter in the company’s history, laying the foundation for decades of success in plastics manufacturing. Today, Terhorst Manufacturing continues to build on its tradition of quality, innovation, and customer-focused solutions, delivering precision-engineered products backed by nearly a century of manufacturing experience.
