This vacuum brazing furnace with a stainless steel chamber is suitable for aluminum alloy and other low melting point workpiece brazing. It can be used as low-temperature sintering, low-temperature heat treatment vacuum furnace.
Vacuum Brazing Furnace with Stainless Steel Chamber Features
- Using a stainless steel metal furnace chamber and electric heating alloy tube for heating, the highest temperature can reach 750℃.
- Electric alloy tube annular heating, high furnace chamber temperature uniformity, up to ± 5℃.
- HMl adopts an HD touch screen, a built-in operating system developed by our company.
- PLC automatic control system.
- Clean stainless steel furnace, equipped with mechanical pump + diffusion pump vacuum unit, the ultimate vacuum can reach 7x 10-3Pa(empty load, cold state).
- Compared with molybdenum foil vacuum furnace, this electric furnace has low power, low price, and economical use. It is an ideal low-temperature brazing equipment.
