Aug 17th 2026
Peters’ Heat Treating Inc. has grown from a small garage operation into one of North America's most respected thermal processing companies. Today, the company serves customers across aerospace, automotive, tooling, and cutlery markets while maintaining many of the same values that guided its founding in 1979.
Many manufacturers rely on thermal processing partners every day, but few know the story behind the companies performing this critical work. During a recent interview with Niagara Specialty Metals, President/Owner Andrew Wilkosz and Blade Division Manager Trevor Kaplin shared the history, philosophy, and growth of Peters’ Heat Treating.
In this article, you'll learn how Peters’ Heat Treating began, what values continue to guide the company, and how it has evolved into a trusted partner for manufacturers across multiple industries.
Quick Answer
Peters’ Heat Treating is a thermal processing company founded in 1979 by Doug Peters in Meadville, Pennsylvania. What started as a four-furnace operation in a one-car garage has grown into a world-class company serving aerospace, automotive, tooling, and cutlery customers while maintaining a strong commitment to quality, innovation, and customer service.
How Peters’ Heat Treating Started in 1979
Peters’ Heat Treating began with a simple observation and a willingness to solve a problem.
According to Andrew Wilkosz, founder Doug Peters worked as an insurance salesman before starting the company. During his travels, he frequently asked manufacturers what they needed most. Time after time, local companies gave him the same answer: they needed a reliable heat treater.
Recognizing the opportunity, Doug founded Peters’ Heat Treating in 1979 with four small furnaces, a one-car garage, and a determination to serve the manufacturing community. To help establish the business, he hired the former head metallurgist from Talon, the historic Meadville company known for developing the zipper.
What began as a small local operation steadily expanded as customers recognized the value of reliable thermal processing and responsive customer service.
The Values That Still Guide Peters’ Heat Treating Today
The core values established by Doug Peters continue to shape the company today.
Andrew explained that one phrase appears throughout the company: "It's not who's right, it's what's right." That mindset encourages employees to focus on solving problems rather than protecting individual opinions.
The company also emphasizes communication, accountability, and customer service. While Peters’ now operates advanced equipment and serves highly regulated industries, leadership believes those original values remain just as important today as they were in the company's early years.
Perhaps most importantly, Peters’ strives to become a seamless extension of its customers' operations. Rather than acting solely as a service provider, the company focuses on becoming a solution provider that helps customers overcome challenges and achieve their goals.
This customer-first approach has helped Peters’ build long-term relationships across multiple industries.
Why Peters’ Heat Treating Serves So Many Industries
Peters’ Heat Treating’s broad industry experience helps strengthen its capabilities.
Andrew described the company as "hyper diversified." Peters’ serves customers in aerospace, automotive, tooling, manufacturing, and cutlery markets. Each industry presents different challenges, requirements, and quality expectations.
This diversity allows the company to learn from multiple sectors and apply those lessons across its operations. Knowledge gained from aerospace processing may improve procedures used elsewhere. Likewise, advancements in tooling or automotive applications can provide valuable insights for other customers.
Rather than limiting itself to a single market, Peters’ has built expertise across a wide range of industries. This approach creates a unique knowledge base that continues to grow with every project completed.
As a result, customers benefit from decades of thermal processing experience gained across many different applications.
How Peters’ Heat Treating Combines Experience with Technology
Modern thermal processing requires more than experience alone.
While Peters’ values the expertise of its workforce, the company has also invested heavily in technology and process control. Andrew discussed the company's custom ERP system, which helps standardize processing procedures and document critical information.
The company also maintains an extensive digital footprint. Jobs are tracked, documented, photographed, and recorded throughout the manufacturing process. This allows the team to review historical information, investigate issues, and continuously improve operations.
Andrew explained that Peters’ can review data such as furnace records, thermal charts, oil temperatures, and other process information when evaluating results. This level of documentation helps support both quality assurance and continuous improvement efforts.
The combination of skilled employees and robust documentation creates a system that supports consistency, traceability, and long-term success.
Peters' Heat Treating combines experienced personnel with advanced inspection and straightening capabilities to help customers meet demanding dimensional and distortion control requirements throughout the heat treating process.
Why Peters’ Heat Treating Continues to Invest in the Future
Peters’ Heat Treat continues to evolve while staying true to its roots.
Today, the company operates under second-generation leadership through Andrew Wilkosz and his wife Diana Wilkosz, formerly Diana Peters. Together, they are helping guide what Andrew refers to as "Peters 2.0."
The company has also continued expanding its capabilities. One example is its partnership with Laser Hard, a joint venture focused on advanced laser heat treating technologies. This process allows selective hardening of specific areas with minimal distortion and opens new possibilities across multiple industries.
At the same time, Peters’ continues investing in its blade division, serving knife makers with dedicated expertise and specialized processing capabilities.
By balancing innovation with proven fundamentals, the company remains focused on supporting American manufacturing and helping customers succeed.
Conclusion
Peters’ Heat Treating has come a long way since its founding in 1979. What began as a small garage operation has grown into a trusted thermal processing partner serving customers across numerous industries.
The company's growth reflects more than investment in equipment and technology. It reflects a continued commitment to customer service, communication, problem-solving, and quality. Those values helped build Peters’ Heat Treating and continue to guide its future.
As manufacturing continues to evolve, Peters’ remains focused on providing the expertise, reliability, and innovation customers need to succeed.
