In 1976, what began as a small operation in a 400-square-foot garage grew into one of the most respected names in induction tooling. Today, Induction Tooling, Inc. (ITI), headquartered in North Royalton, Ohio, celebrates 50 years of designing and manufacturing specialized tooling that helps in-house and commercial heat treaters solve complex induction heating challenges across a range of industries, including automotive, aerospace, agriculture, medical, and mining.
Founded by William “Bill” Stuehr, the company was born from a simple observation. While working as a process design engineer at a heat treating company in the mid-1970s, Bill saw clients asking for induction heating that required specialized tooling.
Recognizing the opportunity, he set out on his own. By April 1976, he had delivered his first custom-designed tooling, marking the beginning of a business that would steadily expand over the decades.
Growth came quickly. The company expanded from his home garage to a few different facilities over the decades. In 2005, they finally settled into a 30,000-square-foot facility where they currently house their engineering, manufacturing, and laboratory testing capabilities.
Engineering Solutions for Induction Heat Treating
Induction hardening requires precision, and Induction Tooling has built its expertise around delivering that precision consistently. The company specializes in selective hardening quick-change inductors and related tooling, such as bus bars, adapters, and fixtures used in induction heat treating systems.
By combining advanced design tools with decades of practical experience, the team develops custom solutions tailored to each client’s application. From hardening gears to heating complex shaft and hub components, the team’s engineers work closely with heat treaters to ensure performance, repeatability, and reliability in demanding manufacturing environments. Bringing that stewardship to records, all induction tooling designs have been meticulously maintained since the company’s inception; if ever that custom solution needed to be consulted, the team can and has immediate access to it.
Central to its capabilities is a comprehensive development process that moves from design, machining, and assembly to laboratory testing and metallurgical evaluation. This integrated approach allows the team to test and refine tooling and process parameters before implementation, helping improve quality and meet development timelines. The metallurgical lab also provides a key training experience, allowing designers, engineers, and production workers to see and test the result of their innovation and labor in real-time.
A Culture Built on Teambuilding
While innovation plays a major role in their success, the company emphasizes the people behind the work more than anything. Skilled machinists and engineers with decades of experience collaborate across design, machining, and assembly to produce tooling that meets client specifications. This emphasis on teamwork and continual improvement is reflected in the company’s philosophy, which encourages learning, cooperation, and accountability throughout the organization.
The Next 50 Years
As Induction Tooling marks its 50th anniversary, the company continues to pursue the same mission that sparked its founding: inventing and engineering unique tooling solutions that improve induction heat treating processes. Recognizing the integration of automation happening within the industry, the team continues to research ways to further integrate robotics and automation into their processes, including experimenting with additive manufacturing.
For this company, the milestone is not just a look back at half a century of growth; it’s a reminder that innovation often begins with a simple idea and the determination to build something better.
