MANUFACTURING HEAT TREAT

An Ohio-based company providing heat treatment for the general manufacturing market, Certified Heat Treating, has been acquired by Thermal Process Holdings, an investment vehicle formed by Calvert Street Capital Partners (CSCP).

“We are excited to announce the second acquisition in our strategy to build a best-in-class company that offers a range of advanced services. The Biehn family wanted to ensure the continued success of the business and to provide opportunities for their people. We are intent on carrying out those objectives,” said John Hubbard, chairman of Thermal Process Holdings.

Don Longenette, who has been director of facilities and maintenance with Diamond Heat Treat, another recent acquisition of CSCP, will serve as general manager of Certified during the transition, which will include overseeing vacuum heat treating, atmosphere heat treating, induction heat treating, carburizing, oil and neutral hardening, among other treatments, at the company’s Springfield, Ohio, facility.

“The operating history of Certified dates to 1959, and the company has a solid reputation in the broad spectrum of industries it serves. We look forward to building on that reputation and growing the business. I’m excited to work with Joe Biehn [president of Certified Heat Treating], who will immediately focus his full attention on driving additional sales. Our goal with Certified is to utilize the exceptional quality of the equipment, the expertise and experience of the employees, and to take advantage of the open capacity of the furnaces,” said Longenette.
