Although Spectrum Thermal Processing was technically established in 2013, the seeds of the company were sown decades earlier. 

The Cranston, R.I.-based heat treater was formed way back in 1962 as Hayes Heat Treating. The management team of Hayes Heat Treating purchased the company’s assets from the Hayes family in 2013, and Spectrum Thermal Processing was born.

The connection to Hayes does not end there. All 17 furnaces in operation at Spectrum Thermal Processing, which includes six vacuum furnaces, were designed and manufactured by C.I. Hayes. And the management team at the company has over 70 years of combined experience, most of which was at Hayes. 

Spectrum Thermal Processing serves the automotive, aerospace, military, medical and electronics industries. The Nadcap-accredited company provides a wide range of thermal processes, including: vacuum hardening with 2- or 6-bar pressure quenching using nitrogen or argon, vacuum hardening with integral oil quenching, low-pressure carburizing, vacuum annealing, precipitation hardening and aging, vacuum and furnace brazing, and gas nitriding.

Of all the aforementioned services, vacuum brazing is one of Spectrum Thermal Processing’s specialties. The company uses batch, continuous and vacuum furnaces to meet the highest brazing standards. High-purity, controlled dew-point atmospheres of argon and nitrogen are utilized to avoid discoloration, alloy evaporation and oxidation. Components of simple and complex configurations – in sizes of up to 34 inches long, 22 inches wide and 22 inches high and weights up to 500 pounds – can be treated. Spectrum Thermal Processing can handle a range of materials, including carbon steel, nickel, Hastelloy, stainless steel, steel and titanium. Simultaneous brazing of multiple joints are possible, creating permanent, strong, and leak-proof joints of uniform quality between dissimilar metals.

There are several aspects of the business that set Spectrum Thermal Processing apart from the competition. The company, which currently has 19 employees, is AS9100D and ISO 9001:2015 certified, proving its dedication to the aerospace industry. AS9100 takes the
ISO 9001 requirements and supplements them with additional quality system requirements, which are established by the aerospace industry in order to satisfy DOD, NASA and FAA quality requirements. Along those lines, Spectrum Thermal Processing has several prime aerospace approvals, including Boeing, Lockheed Martin, Triumph and Parker Hannifin. The company also provides door-to-door pickup and delivery (Massachusetts and Rhode Island on Tuesday and Thursday; Connecticut on Monday, Wednesday and Friday).

And that isn’t all. In an effort to be a true one-stop shop for processing, Spectrum Thermal Processing boasts a complete in-house metallurgical laboratory. In addition, on-site audits, site inspections and customer service meetings can be easily scheduled.  

As for the future, the company plans to invest in instrumentation upgrades and equipment maintenance. Spectrum Thermal Processing also aims to continuously train its employees to maintain its accreditations and approvals and to provide a broad base of services to customers.
