Soldering Process: Ultrasonic Cleaning → Apply Solder Paste → Vacuum Drying → Vacuum Soldering

1350°C Silver/Copper/Nickel-based Vacuum Brazing Furnace (Molybdenum Foil Hearth)

This vacuum brazing furnace operates at temperatures up to 1350°C; suitable for high-temperature vacuum brazing using silver/copper/nickel-based brazing agents. It can also be used for sintering and heat treatment of other workpieces.

1350°C Silver/Copper/Nickel Alloy Vacuum Soldering Furnace Features

• Utilizing molybdenum foil as the metal furnace chamber and molybdenum heating strips as heating elements, temperatures up to 1350°C can be achieved.

• The molybdenum heating belt is circularly distributed inside the furnace, with radiant heating around the periphery, ensuring high uniformity of the furnace temperature, which can reach ±5 degrees.

• Clean molybdenum foil furnace chamber, equipped with a mechanical pump + diffusion pump vacuum unit, cold vacuum level 10^(-3) Pa; working vacuum level 10^(-2) Pa.

• As needed, inert gas can be injected for accelerated cooling.

• Optional accessories for 1350℃ silver/copper/nickel-based vacuum brazing furnace

Due to the slower cooling rate of conventional brazing furnaces, it severely affects production efficiency. To accelerate the cooling speed, our company, with years of production experience, has developed a rapid cooling system for vacuum brazing furnaces. The high-temperature nitrogen inside the furnace is forcibly extracted by the vacuum blower, then cooled down in a cooling water tank before
The material is sent back into the furnace by the vacuum blower. This rapid back-and-forth cycle achieves a quick cooling effect.

• External rapid cooling system; from soldering temperature to 180 degrees in less than one hour.

• Stainless steel multi-layer material racks, convenient for placing multi-layer brazing workpieces.

• High-quality American imported welding flux.
