It’s Vertical – It’s Horizontal…It Flips!
The T-M Vacuum VH-HV Flipper furnace is the first of its kind, remarkable versatility for all of your developmental and production needs. Within its all-stainless steel chamber is a horizontal 6″ x 6″ x 12″ deep work zone that can also be flipped vertically for an 8 ̋ x 12 ̋ work zone. With capabilities of up to 50 pounds of material for brazing, tempering, austenitizing, hardening, stress relieving, sintering, bonding, and many other custom processes.
With its standard all metal hot zone a precision heating environment of up to 2000°C can be achieved with precise temperature uniformity.
The specially designed hot zone to chamber ratio enables a faster pump downtime utilizing its standard turbo-molecular pumping system. Add the inert gas on-board quick cool system and your process times can be remarkably fast!
Once you have determined your specific process parameters, enter it into the touch screen PLC control system and you have a completely automated process with data logging!
The VH-HV Flipper furnace is a completely self-contained unit, requiring no reassembly at your facility, and it is compact for floor space economy! Simply plug connect your electrical service, water, gas, and air and away you go!
