The Global Vacuum Furnace System are the high
temperature technically advanced vacuum furnace to satisfy all your
heat-treating needs. Within the stainless steel of the vacuum furnace are two
cubic foot work zone capable of holding up to 80kgs of material for
tempering, austenitizing, hardening, stress relieving, brazing,
sintering, bonding, annealing, and many other custom heat treating
processes
Obtaining perfectly heat - treated product is easy with our vacuum Furnace. With our standard
electro-pneumatically operated “heat pack” door shield assembly, a
precision heating environment is created for optimum temperature
uniformity, which is ideal for annealing and tempering processes. With its inert gas on board quick cool system the
metallurgical gas quench increases your cycle times by rapidly
cooling the chamber and increasing your product output. And our
specially designed Hot Zone-to-chamber ratio in our vacuum furnaces enables the pumping system to reach vacuum quicker, maximizing your productivity and
work quality with a clean work environment.
The Vacuum Furnace system, is a cost cutting machine.
Their color touch panel PLC control technology, is a completely
automated control system requiring an operator to only load and
unload the system and press the start button.
The system is completely contained unit with no exposed wires, cables or pumps. This saves your valuable floor space and
provides a clean presentation in your facility. The Vacuum furnace
system is easy to install and simple and fast to maintain with the fully removable hot zone.
