Economical Vacuum Furnaces

T-M Vacuum Tool Room Vacuum Furnaces are the high temperature, technically advanced vacuum furnaces to satisfy all your heat-treating needs. Within the all stainless steel chamber of the vacuum furnaces are two cubic foot work zone capable of holding up to 200 pounds 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 furnaces. 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.

Tool Room Vacuum Furnaces are cost cutting machines. 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 Tool Room System is completely contained unit with no exposed wires, cables or pumps. This saves you valuable floor space and provides a clean presentation in your facility. The Tool Room Vacuum Furnaces are easy to install and simple and fast to maintain with the fully removable hot zone.

If you are looking for higher vacuum level capability or the Tool Room Series work zone is not large enough for your sintering, tempering, brazing, medical or other special heat treating application, see our SUPER, PACER, or PERFORMER Series vacuum furnaces.
