Exactatherm

What Exactatherm does

Exactatherm Limited is a Mississauga, Ontario-based provider of specialized industrial heat treatment services, founded in 1979 and operating with an estimated 11-50 employees. The company delivers a portfolio of eight thermal processing services—Vacuum Oil Quench, Vacuum Gas Quench, Ion and Plasma Nitriding, Age Hardening, Stress Relieving, Solution Annealing, Cryogenics Treatment, and Vacuum Annealing—to customers in aerospace, automotive, defense, medical, nuclear, power generation, tool & die, and general manufacturing. The company positions itself around vacuum-based heat treatment and surface enhancement processes that improve durability, strength, dimensional stability, wear resistance, fatigue strength, and corrosion resistance of metal components while preventing oxidation and decarburization.

Technically, the company operates capital-intensive equipment including Seco Warwick vacuum furnaces (vacuum oil quench up to 3,000 lbs; vacuum gas quench with up to 10 Bar Nitrogen Quench), Ionex and Bernard Engineering ion/plasma nitriding systems (up to 12,000 lbs capacity with a 56" x 65" x 85" furnace chamber), and cryogenic treatment reaching temperatures below -300°F (-184°C) using liquid nitrogen, along with multiple tempering ovens. Its regulatory and quality posture is central to its offering, holding NADCAP AS7102, SAE AS 9000, ISO 9001:2000, AMS2759, and Controlled Goods Program certifications, plus approved-vendor status with Boeing and Bombardier.

The business model is a sales-led, quote-based professional services operation. Customers submit requirements through an online quote request form and receive customized per-project pricing based on material specifications and processing complexity; no public rate cards or standardized tiers are disclosed. Go-to-market is direct B2B enterprise/industrial sales, supported by the company website, an active news/blog section, and trade show participation (CMTS 2025). Components are shipped to the Mississauga facility for processing. In July 2024, Exactatherm was acquired by Metex Heat Treating Ltd—described as the largest heat treater in Canada—and now operates as a separate brand within the Metex family of companies alongside sister entity Durasort.
