  • Vacuum Furnace Vacuum Furnace A vacuum furnace is a device in which products are surrounded by a vacuum environment during the processing. In this vacuum state, the presence of air or other gases is eliminated, preventing oxidation, reducing heat loss through convection, and eliminating contamination sources. The vacuum furnace offers advantages such as enabling defoaming processes, preventing uneven heating, and effectively suppressing workpiece deformation. It is commonly used in processes like annealing, brazing, sintering, and heat treatment, providing high consistency and low contamination.
    Since heating is carried out while the vacuum pump evacuates the chamber, it efficiently removes gases adhering to the processed products. Our ferrofluid feedthroughs, ferromagnetic fluid seals, and vacuum rotary feedthroughs are used in the rotating inlet part of fans for circulating pressurized gases. The ferrofluid/ferromagnetic fluid seals, designed using our proprietary analytical techniques, offer high load resistance and high torque transmission.
