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.

“No Jerks” Rule, with Sarah Jordan
Sarah Jordan Founder & CEO Skuld, LLC
For Sarah Jordan, president and CEO of the cutting-edge casting startup Skuld LLC, hard decisions have paved the path of her career. An earnest visionary — and as down-to-earth as they come — Sarah has made a habit of launching startups for the metal processing industry. Today, she leads a team that has developed a toolless, net-shape casting process and the equipment to perform it, advancing the way parts are formed while minimizing post-processing needs.
It comes to no surprise that her hardest decision came while forging this path. In 2009, Sarah’s first startup, Aesir Metals, faced fall-out from the 2008 economic recession. The impact was most acute when their largest customer informed them that they were unable to pay.
Faced with this reality, Sarah had to make the painful choice to close the company. Just after Christmas that year, every employee was let go. “And that’s awful when everybody’s…you know, they’re counting on you, their families are counting on you.” It was her first time navigating such a challenge, and while it was difficult, it became a formative experience.
Leading her current company, Sarah operates with a “‘no jerks’ rule.” She says culture and people are critical, and the postmortem of Aesir Metals revealed other opportunities for improvement. While mistakes are inevitable — learning requires that — she moves forward, determined not to repeat the same ones.
Upgrade Your Skillset, with Kevin Walters
Kevin Walters Research & Development Manager OMG Inc.
Kevin Walters‘s official title is R&D manager at OMG Inc. out in Massachusetts — however, his nickname “Father of Interns” is extremely fitting. With decades of engineering experience, Kevin has dedicated 25 of them (and counting) to mentoring interns, first at Spalding Sports Worldwide and now at OMG. Using his own career for reference, he tells them this story.
Approaching his forties with four boys near or in their teenage years, Kevin began thinking seriously about his career trajectory. He knew that to stay relevant in engineering, he needed to expand his skillset. In this field, the rule is simple: upgrade your abilities or risk becoming obsolete. The question was how.
“I’m a guy who likes to fix stuff — work with my hands,” Kevin told me. The typical career-advancement routes didn’t seem like the right fit: waiting for an opportunity to open up in the company could take too long, a doctorate might pigeonhole him into academia, and an MBA didn’t align with his engineering focus. It took five years of consideration, conversation, and research to find the right path.
That opportunity appeared when he learned about a management degree specifically tailored for engineers. With Spalding’s full “blessing” and tuition reimbursement program, Kevin enrolled at Western New England University, taking two courses per year while balancing his job and his sons’ baseball games. In five years, he had earned his Master’s of Science in Engineering Management.
These kinds of programs have become more widely available, and Kevin encourages his interns to pursue them. “Engineers, if they don’t upgrade their skillset, become obsolete,” he says. “I see too many engineers who graduated with their four-year degree — did great things at the beginning of their career — but because technology is advancing and they’re not learning with it, they are not as useful as they used to be.”
Each summer, Kevin continues mentoring one or two interns, urging them to think strategically about building their résumés and preparing for an industry that never stops moving.
It’s the People, with Dan Bender
Dan Bender Director of Sales Control Concepts
As Dan Bender reflects on his 47 years in industry, many as director of sales at Control Concepts, one priority has guided him: bring in business so the people in manufacturing have a job, can feed their families, and keep a roof over their heads.
In the late ’80s and early ’90s, there were a lot of mergers and acquisitions of companies by holding firms. A general attitude that “work is work” within industry started to emerge. He observed that people were being treated as just another factor of direct manufacturing costs.
This inhumane approach was augmented by a larger lack of pride in the business by the leadership. He also perceived that businesses were treated as financial investments; leadership seemed to be just concerned with flipping the company for a profit. Eventually, these factors reached Dan’s workplace.
Desiring more from his employer and wanting to be useful and productive in a place where people mattered, he parted ways. He reflects, “I left a pretty good job and went out to try some other things, realizing I still had a family to support.”
Over the next few years, he explored different roles, leaning on the counsel of friends and mentors from outside the heat treat industry, many of them from his church. Then, in 2008, the recession hit. Dan was working for a European company when it eliminated nearly all North American positions, and for the first time in his career, he was out of a job.
“That was tough,” he commented. “That was a hard, a hard thing…I did some interviews, I had some possibilities, I had some decent things, but I wanted to find somewhere where…people are important.”
His faith was central to that search, and in time, he found the right fit at Control Concepts. While it was not the best offer at the time, it was “what made me feel good, and it [did turn] out to be very financially rewarding for me.”
Choosing to stick with his principles also meant staying in an industry where he had built decades-long relationships. Dan says he looks forward to seeing those connections at tradeshows like Heat Treat 2025 this fall and Furnaces North America next year. “It’s to me, you know…that’s a blessing that I can have conversations with those people and feel a real sense of knowing they are very interested in what you’re doing as well as you being interested in what they’re doing at this stage in their career and your life.” Serving the heat treat industry, and the people in it, is why Dan has no plans to retire anytime soon.
Never Stand Still, with Bill Stuehr
William (Bill) Stuehr President & CEO Induction Tooling Inc.
What do you do when an unforeseen market collapse changes the fabric of your business? William (Bill) Stuehr, engineer, founder, and CEO of Induction Tooling Inc., has a clear answer: make a plan and move forward. “I’m a pragmatist,” he says. “I look at things the way they are, then I make decisions and proceed with what has to be done. That’s all.”
In 2005, Bill built a brand-new facility to expand his operations from 14,000 to 30,000 square feet. Business had been picking up for induction heating since the 1980s and ’90s, and manufacturers of driveline components were interested in induction. Induction was becoming more accepted on two fronts: first, as a green energy source; second, as an integrated manufacturing step in cell production, allowing automotive components such as wheel bearings and axle shafts to come out finished at the end of the line. With the expectation to expand to 50 employees by 2015, the city even granted Induction Tooling a tax abatement to encourage expansion and boost the local economy.
The critical moment happened in 2009, beginning on the heels of the 2008 financial crisis. With the housing collapse, people stopped purchasing automobiles, and the automotive industry went reeling. In April and June, General Motors and Chrysler appeared before U.S. Congress after filing for bankruptcy. Bill’s tier 1 automotive manufacturing customers began shutting down operations. “I had never seen it in my career, ever.”
Work was running out. Bill made the hardest decision of his career: “I had to lay off half of my workforce. I went from 28 people to 14 in less than a year.” Some of them had been with him since he started in the late 1970s. “It was out of my control. I tried to keep them on as long as possible without suffering the financial hardship of my own.” Even in hard times, the company covered all employee medical insurance, a practice Bill maintains to this day.
By 2012, the market showed signs of recovery. Bill pivoted the business to focus almost exclusively on CNC automation for rebuilding tooling — a move that met the needs of their tier 1 customers with high production rates and sidestepped the challenges of rehiring or retraining a large workforce.
Commenting on today’s market, Bill revealed it had never truly recovered. “The buyers of the automotive companies had the time to seek outsourcing worldwide.” He continued, explaining that over the course of the four years that followed the crash, there was enough offshoring of driveline components to an enthusiastic, energetic workforce with new facilities and abilities. Reshoring to the U.S. has not gained back the momentum that it had, though perhaps that will change with the priorities of the current U.S. administration.
From those years came a few lasting lessons. First, embrace automation to keep the business profitable, especially when attracting young talent is a struggle. Second, when hard times come, make a plan and commit — but remember that you can’t control time, the weather, or other people. Bill sums it up with gritty simplicity: “You never stand still; you just keep going. ‘What do I have to do and how can I get it done?’ That’s it.”

How should you maintain induction coils used in hardening applications? Elbow grease — a little goes a long way. After each use, a simple solution of soap and hot water will remove sticky quench and debris. Scrub hardened dirt with a Scotch-Brite pad. Check for pitting, arcing, and insulator damage. If all is good, use a hot water rinse, and it’s ready for use. If the inductor is to remain on the machine for an extended period, it is advised to wash it and the associated bus daily. Check for damage. Following this simple procedure will reduce business waste.
As industry tries to become more “green,” a number of companies are switching from lubricants that are petroleum or mineral oil-based to water-based (“aqueous”) lubricants instead. However, some of these companies then make the mistake of not changing their degreasing fluids that they use to remove these lubricants prior to their next processing operations, and stay with their standard degreasing fluids, such as acetone or alcohol, which are not effective at fully removing water-based lubricants. Instead, they need to run tests to find an appropriate alkaline-based degreasing fluid for such water-based lubricants, since alkaline-based degreasers will be effective at removing such lubricants. Commonly available dish-detergents (alkaline-based) have been shown to be highly effective for such use.
