Not so fast says Eric Wilson, COO of “The Dayton Forging & Heat Treating Company” just down in the road in Dayton, Ohio. According to him, his company has been in continuous operation since 1919 making it just 2 years older than “Queen City”
Anybody else out there that would like to step up?
“OCTOBER 23, 2025. Oldest Continuously Running HT in North America Now Has Single Owner; Earlier this week “The Monty Heat Treat News” had a news item entitled “Heat Treat 2025”-Things You Have to Know“. This news item featured a number of trivia points about the heat treatment industry which every heat treater worth their salt should know.
A reader responded with a question addressed to “The Monty” team-“what is the oldest continuously running commercial heat treat in North America”–“The Monty” team got it wrong with our answer of“Bennett Heat Treating”in Newark, NJ founded in 1923.
It turns out the correct answer is “Queen City Steal Treating”, in Cincinnati, Ohio founded way back in 1921-it is believed that they are the only remaining charter member of “Metal Treating Institute” MTI – (our news item below features MTI).
In related news it is our understanding that “Mrs. Judy Rudy”, the longstanding and very competent President of the firm bought out her business partners earlier this year and is now sole owner of the company-a very impressive feat.”
In a very discrete, unpublished way it would appear that a Nadcap accredited captive heat treater in Phoenix, Arizona, USA by the name of “Joined Alloys”was recently acquired by a firm based in India.
This is how “Joined Alloys” describes their heat treatment/brazing capabilities:
“We specialize in furnace brazing with nickel, copper, and precious metal braze alloys. Heat treating services are performed in a vacuum and in hydrogen, and inert gas atmospheres. Typical heat-treating processes include stress relieving, normalizing, solution treating, precipitation age hardening, and tempering of exotic alloys.
Our in-house brazing capabilities allow us to provide our customers with advanced bonding solutions for use in fabricated components and assemblies. Heat Treating, Brazing and Non-Destructive Testing are NADCAP accredited.”
This press release from “TASE” Describes the Acquisition;
“NOVEMBER 2025; Chennai, India-based Trusted Aerospace Engineering (TASE Global) has completed its acquisition of Joined Alloys, a US-based firm specializing in aerospace manufacturing, special processes and specialized sheet metal fabrication and product development, for $12 Million USD.
TASE Global is a diversified manufacturing and technology group with operations across Europe, Asia and the Americas. The company specializes in precision manufacturing of components and providing solutions for aerospace, medical and industrial applications. It has factories in the US and India, along with offices in Portugal and France.
“Joined Alloys brings a legacy of technical excellence, strong client relationships and a culture of integrity that aligns with our own,” said Sankararaman Vaidyanathan, Chairman, TASE Global. “The acquisition is a part of our forward integration process that unlocks synergies in aerospace manufacturing, defense and medical applications, allowing us to pursue more ambitious projects across industries. TASE Global shall be an end-to-end strategic partner to large Tier 1 players.”
September 3rd “The Monty” had the exclusive news story below about a Michigan, USA heat treater installing one of the “Largest Vacuum Furnaces in the US Midwest”. As an update to this story we have these notes from “Darby Metal Treating” and this video.
“Today, DMT took delivery of a new vacuum hardening and annealing furnace and this one is an absolute unit. Work zone dimensions are 52″ W x 109″ L x 40″ H, with up to 5 bar nitrogen quenching capability. The furnace vessel alone was so large that we had to widen the opening for our roll up door to get it in the building. Stay tuned for further updates on installation and production readiness for this exciting addition to our heat treating equipment and thanks to our friends at Kandler Tool Company for a flawless setting on our shop floor!”
In that article we suggested the firm might be installing a very substantial vacuum furnace in the near future-we can now confirm that, that rumor has proved to be correct and “The Monty” can give you all the details in this exclusive story.
The furnace was manufactured by “TAV” and has working dimensions of 52″ X 40″ X 102″-making it not the largest in the Midwest but probably close to it. It has a maximum working temperature of 2,400F, an ultimate vacuum level of 10-3 torr (range) and up to 5-bar quenching with either argon or nitrogen. This almost new furnace came out of an aerospace facility in the western USA and was very lightly used, so much so that we would consider it in like new condition.
While we do not have a definite date as to when it will enter production, we would expect it to be within the next couple of months-certainly before the end of the year. These photos show the furnace at its previous location.”
At the recent “Heat Treat 2025“ exhibition in Detroit, Michigan, USA “Gord & Jordan Montgomery“ of “The Monty Heat Treat News”ran across DMP of Texas a supplier of +1200 to -300 thermal processing systems. During our conversation we learned that Jim Wells, part of the original DMP team recently returned to the company after a brief “hiatus”.
“For more than three decades, Durable” Metal Products (DMP) has been a trusted leader in the design and manufacturing of cryogenic and thermal-cycling systems used throughout the heat-treating industry. With over 250 installations worldwide, DMP’s reputation for precision, reliability, and Made in the USA craftsmanship continues to set the benchmark for quality.
Founded on the principles of innovation and integrity, DMP has remained dedicated to building durable, high-performance equipment such as the CryoFurnace™, CryoTemper™, and CryoFreezer™—machines known for delivering accuracy within ±10°F and years of dependable service.
After a brief hiatus to explore new opportunities, Jim Wells—a familiar and respected name in the heat-treating community—has returned to DMP, bringing renewed energy and insight to the company’s next phase of growth. His leadership and technical expertise are once again helping to guide the team toward advancing cryogenic technology and enhancing production efficiency.
Today, DMP is proud to announce that it is actively developing a new system that promises to push the boundaries of thermal cycling performance even further”.
Today we speak with “Mr. Francesco Pieropan”, CEO of Italian furnace builder “Meapforni“.
We are indeed fortunate today to have an interview with an individual who we have known for a number of years and one whom we have a very high opinion of, Mr. Francesco Pieropan, of furnace builder “Meapforni” of Italy. Francesco, I appreciate the time, lets start off with your personal background, in particular how you ended up in the heat treatment industry.
“After my university studies I met a family friend who introduced me to the world of furnace producers, this was 1984, and at the time I worked for a company called “Elsima”, which produced mainly mesh belt furnaces for brazing and sintering. My first goal was to expand the market and it was a pleasure for me to start travelling to countries such as France, Spain, USA and Canada.
Earlier this year I was able to visit your facility, the original article can be found at “Furnace Builder “Thrives” Over the Past 8 Years”, however perhaps you could in your own words tell us the history of the company?
“After many years with other larger furnace builders, some colleagues and myself, decided to group together and transform our experience in a new challenge- “Meapforni” was the result.”
What is your position with the company-I believe you have partial ownership of the company.
“Yes that is correct, I have shares of Meapforni and my position is CEO”.
My impression of “Meapforni” is that you can offer many different furnace designs, more than the average furnace builder it would appear. This is a rather “round about” way of asking what types of furnaces have you built over the years?
“When we started we decided to concentrate on the products and applications we were very familiar with and had a great deal of expertise in so we could deliver a high quality product. This is why we started with automated batch and mesh belt lines for fasteners. At the same time we were receiving requests from our customers for different applications which means we have built and delivered vacuum furnaces, nitriders , rotating and roller furnaces.”
Do you have standard product offerings, or would you consider yourself more of a “custom” design firm?
“Definitely we are a custom producer although we try to use standard assemblies and sub assemblies, but our strength is the capacity to deliver a highly tailor-made product.”
You are based in Italy but is that your largest market? Historically where have the majority of your furnaces shipped to and do you see this shifting in the short or medium term? For instance, do you see North America becoming a larger market for you?
“Yes we are based not far from Venice in the northeast part of Italy. The Italian market is not our largest, we work mainly abroad, and Europe and Switzerland are our main markets. We are concentrating on becoming more global, and for this reason we are working a lot to find agreements and alliances. North America is for sure a very important market for us and we hope to have more possibilities to start there also”
Are there any new technologies you are looking at that you have not offered before?
“For the moment we are too busy with our existing products, our focus now is to expand our applications to various fields, for example medical, aerospace and defence.”
Earlier this year you mentioned you that you had received some very interesting orders, one in particular which involved salt quenching I know you were very proud of. Are you able to share any details about this project now? Are there any other “intriguing” projects which you can tell us about?
“Yes we recently delivered a fully automatic mesh belt line to a European leader when it comes to producing garden appliances andproducts. The line was built using the latest concepts of carbon reduction technologies, has a capacity of 1 ton per hour, and was designed from scratch to fit into an existing area. We are also working on some new projects where argon is the atmosphere but at the moment we cannot say more”
The heat treat industry is seeing challenges these days but this is hardly unusual. In North America the number one issue is a shortage of good, experienced people. Is this an issue in Europe or are you facing other “problems”?
“Meapforni is facing the same scenario, although we are lucky because we are in an area where there are a lot of small and medium companies very skilled in what we produce who can help us as required. At the same time our company is working to add young, talented people that will help our existing staff.”
North Americans look at energy costs in Europe with absolute shock, how do these high energy prices effect furnace design and what solutions is “Meapforni” offering?
“You are right, Europe, especially during and after the Covid period, has faced an incredible increase of costs not only regarding gas and electrical supply for furnace heating but also for all technical gases used for heat treatment. This is why a lot of “old furnaces” are no longer competitive and have been scrapped. We have worked a lot on insulating materials quality and the way they are applied along with software modes to optimize the use of the furnace heating during every moment of production and non production time.”
Francesco how do you see 2026 shaping up for your company in particular and the heat treatment industry in general?
“Europe has faced an important deceleration over the last couple of years for reasons which are known around the world. Our company is trying to work on special niche markets and offering super personalized solutions, this we believe will help us to face a very good 2026 which is to say we are excited about the future.”

Everybody in the heat treat industry knew that this would lead to changes in the structure of the company in North America, the only question was-what shape will these changes take? We are now getting a glimpse.
According to this press release each of the component companies will now operate under the name “Aichelin Americas” which we assume means that over time the “AFC-Holcroft”, “Atmosphere Heat Treating, Inc.”, “Austemper, Inc.”, “Nitrex NTS” (Nitrex, G-M Enterprises, and UPC-Marathon) names will all slowly disappear.
We also see some changes in the North American management structure with Tracy Dougherty (formerly CEO of AFC-Holcroft) now “President of Sales & Service, Aichelin Americas and Paul Oleszkiewicz, now President of Operations.
The fact that Mr. Oleszkiewicz is now President of Operations is very interesting. Paul is a long time Nitrex Manager in Montreal, Canada who is very experienced and very professional, this marks a major promotion for him, one which we would consider well deserved.
While it is too soon to know for sure our bet would be that the next step in this acquisition will means changes in the sales network of each division. We will keep you posted.
“Atmosphere Group Announces Rebranding to Aichelin Americas; The Atmosphere Group has been an operating holding company in the USA for its subsidiaries: AFC Holcroft, Atmosphere Heat Treating, Inc., and Austemper Inc. (Previously, Austemper Inc. was announced to be consolidating with Atmosphere Heat Treating.) With the addition of new subsidiaries—Nitrex NTS (Nitrex, G-M Enterprises, and UPC-Marathon)—from a previously announced acquisition, we are pleased to announce that our operations for Region Americas will henceforth operate under a strengthened and unified identity: Aichelin Americas.
Marty Poljan will continue to lead the region as President and CEO of Aichelin Americas. Poljan began with the group in 2021 at Atmosphere Heat Treating and, in 2023, assumed the role of President and CEO of the Atmosphere Group.
Aichelin Americas is proud to announce that Tracy Dougherty has been promoted to President of Sales & Service, Aichelin Americas, and Paul Oleszkiewicz to President of Operations, Aichelin Americas. Together, Tracy and Paul bring more than 50 years of leadership experience in the heattreating industry. Both leaders have distinguished careers in leading high-performing teams and fostering positive company culture. This level of embedded industry experience sends a clear message: while corporate structures and brands evolve, the people responsible for delivering performance, service continuity, and technical accountability remain deeply rooted in the realities of this industry.
With the strategic alignment of Nitrex NTS, AFC-Holcroft, and Atmosphere Heat Treating, Aichelin Americas is not simply expanding—it is reinforcing its long-standing commitment to serve as a trusted technical partner to OEMs, commercial heat treaters, and specialized processors across North and South America.
The team at Aichelin Americas is passionate about providing industry-leading solutions to our equipment and service customers.
“Our customers don’t simply buy equipment—they make a long-term decision about who they can rely on,” says Poljan. “This leadership structure reflects that reality. We are here to be a consistent, service-driven partner—not just at installation, but through every maintenance cycle, modernization, and capacity expansion that follows.”
On the commercial front, Tracy Dougherty, now President of Sales & Service, brings over 17 years of direct sales and customer lifecycle experience from AFC-Holcroft, navigating both OEM furnace projects and aftermarket service partnerships.
“This industry has shifted,” notes Dougherty. “Customers expect more than a transaction—they expect responsive service, modernization support, and clear accountability over the lifespan of their equipment. That’s where our focus is, and where it will remain.”
Delivering on that promise operationally is Paul Oleszkiewicz, President of Operations, whose three decades at Nitrex have been dedicated to engineering execution, process reliability, and technical precision.
“Engineering leadership in heat treating comes down to repeatability and trust,” says Oleszkiewicz. “A furnace isn’t just a product—it’s a long-term production system. Our responsibility is to deliver with consistency and to stand behind that equipment with real technical support.”
As Aichelin Americas continues to align its manufacturing capabilities, aftermarket service network, and engineering resources across its combined brands, customers can expect more than just broader product coverage—they gain access to a leadership team that has lived the operational realities of all things thermal processing”.
