Induction Heating Vacuum Furnaces

GH Induction Atmospheres vacuum furnaces are designed to operate with quick, clean induction heating. "When compared to a traditional large vacuum furnace system, VF Series Vacuum Furnaces can reduce overall cost of ownership by as much as 75%," said a company spokesperson.

"Brazing or heat treating in a high vacuum environment offers a high degree of process control and produces exceptionally clean parts free of oxidation and scaling," added the spokesperson. In a vacuum system, parts are loaded into a steel chamber, which is then pumped free of air and other gases. "In contrast to flame heating and resistance heating, a vacuum furnace heats the entire part and not just the joint area," said the spokesperson.

The most common applications for vacuum furnaces include heating small lot sizes, brazing parts of unusual shapes, repairing "orphans" from other heating processes, and other applications that benefit from whole part heating. "It is easy to set up a continuous manufacturing flow, run various processes throughout the day and realize up to 90% improvement in overall cycle time," said the spokesperson.

GHIA vacuum furnaces are designed to heat parts of virtually any shape in a high temperature, high vacuum environment or in partial pressure of an inert gas.

To permit easy loading, the part handling mechanisms on GHIA vacuum furnaces open at the base of the system, which then automatically raises the parts up into the vacuum chamber and heating coil, and finally lowers the parts back down to base level for unloading. The chambers are mounted on heavy duty frames that house all the required equipment for vacuum, atmospheric and system control, as well as the induction heating station.

Real time monitoring and SPC are accomplished with the optional LAN interface or digital chart recorder; data may be stored and sent directly to a desktop computer. The standard thermocouple controls record all chamber temperatures. Individual part temperature may be controlled and monitored with the optional optical pyrometer.

To maximize operator safety, GHIA vacuum furnace heating systems are fully isolated. Safety interlocks protect access to the vacuum chamber and manual controls.

Other operator safety features include a light curtain, emergency stop and other warning systems built into the software and hardware.

The furnaces feature a small footprint to fit within a manufacturing cell, and are available in three standard configurations or built to customer specifications.
