Exactatherm Ltd.
Exactatherm is a leading company for vacuum processing
in North America. It was the First to introduce ionitriding
surface treatment, vacuum oil quench heat treatments and
cryogenics to the Canadian metal working industry.
Ionitriding capacity, in three Toronto area plants,
is the largest in North America.
We pick up and deliver parts to our customers.
Processes include Ionitriding, PVD (Tin) Coating,
Cryogenic, Vacuum Heat Treating, Vacuum Annealing,
Age Hardening, Nitriding, Carburizing,
Neutral Hardening, Marquenching, Solution Treatment,
Tempering and Selective Treatment.
Quality Assurance
Exactatherm's QA Manual is in compliance with
MIL-I-45208, MIL-STD-45662 and AQAP-4.
Equipment at Exactatherm meets the following specifications:
Vacuum - MIL-H-6875, AMS-2750
Ionitriding - AMS-2759/8
Hardness Testing - ASTM-E18
For process control, all plants are equipped with a minimum
of two hardness testers capable of standard and superficial
testing and also one portable hardness tester for large sections.
The equipment is serviced every three months by an external
source and calibrated to national standards.
A metallographic laboratory is located at Head Office in
Mississauga equipped for metallographic examination,
micro-hardness testing and hardness profiles.
Certification
Exactatherm is qualified to perform
Certified Heat Treatment Services for aerospace, defence and
nuclear industry customers including,
AECL, Dehavilland, Devtek, General Electric, Indal Technology,
Litton Systems, McDonnell Douglas, Menasco Aerospace,
Pratt & Whitney, Rolls Royce (Canada) and Spar Areospace.
The QA Manual is available for inspection through the QA Manager.

Vacuum Heat Treating
Metal parts are heated in a vacuum chamber. An applicable
process temperature and cooling rate are selected to
produce the desired transformation in the metal for wear
resistance, toughness, strength and/or corrosion resistance.
Typically, tools, plastics, moulds, metal castings, dies
and machine parts are vacuum treated when surface quality
must be maintained during service life.
Ionitriding
Metal parts are heated in a vacuum chamber to a
process temperature at which point process gases
are introduced and electrically energised by the
chamber wall to produce a glow discharge.
Nitrogen is diffused into the metal parts surfaces and
combines with certain elements to form hard nitrides.
Typically, tools, form dies, forging dies, metal castings
and plastics machine parts are ionitrided when surface
wear resistance or corrosion resistance must be improved
with minimum dimensional changes.
Cryogenics
Parts are slowly cooled in a refrigeration vessel and
held at a process temperature between minus 300-320 F,
using liquid nitrogen as the refrigerant.
Parts are slowly brought back to room temperature after
the hold cycle is complete. Subsequent tempering is
required on some materials to complete the process.
Typically blades, broaches, fine blanking dies, carbide
inserts, cutters, gauges and gun barrels benefit
from the martensite and fine carbides formed during
cryogenic treatment that improve stability, resistance
to wear and chipping.
Stress Relieving
Parts are heated in a furnace to a process temperature.
The rate of heating and cooling and the process temperature
are determined by the application requirements.
Typically, welded fabrications, heavily machined/ground
parts, drawn/cold worked parts and raw material are
often stress relieved to remove residual stress
that could eventually cause a part to distort, rupture or fail
in some way.
