Estab‍‍‍lished in 1979, Exactatherm is one of North America’s leading companies for vacuum heat treatment processing of metals used primarily by the Aerospace, Automotive, Mould and Tool & Die Industries.

Exactatherm Limited is committed to maintaining its position as a market leader and world class provider of heat treatment and advanced surface technologies. Under the leadership of Dr. Peter Lidster, Exactatherm was first to introduce a variety of advanced thermal processes to the Canadian Metal Working Industry. These include ion nitriding, vacuum oil quench hardening and cryogenic treatment. In 1996 Exactatherm built an Advanced Coating Centre at its Mississauga facility and now offers P.V.D. and C.V.D. hard coatings. Under Peter’s leadership a highly innovative and experienced team has been developed.

Service and capacity is provided from our convenient located plant in the Greater Toronto Area and regular pick-up & delivery is available for an increasing number of customers. With state of the art technology and equipment, the combined capacity for ion nitriding and stress relieving rates as one of the highest in North America. The capacity for heat treatment of tool steels is exceeded by very few.

Quality Assurance is of paramount importance at Exactatherm, an Nadcap AS7102, Controlled Goods, ISO 9002-94 & SAE AS 9000 registered company that continues to build a national reputation for quality and service among its large customer base.  A Quality Control Laboratory is located at the head office in Mississauga and the Quality Control Manual is available for inspection through the Q.A. Manager. All testing equipment and procedures are in compliance with modern national standards; each piece of testing equipment is checked and serviced every three months by an external source to maintain accurate calibration standards.

Certified heat treatment services are performed for a diversified group of loyal customers from the Aerospace, Automotive, Defence and Nuclear Industry that have contributed to much of Exactatherm’s ongoing growth.
