Continuous Vacuum Brazing Furnace

Continuous Vacuum Brazing Furnace for Fully Automated High-Volume Brazing Production

The Continuous Vacuum Brazing Furnace is a high-efficiency automated thermal processing system specifically designed for continuous vacuum brazing, aluminum brazing, and high-temperature precision joining applications.

Engineered for industrial mass production, the system integrates automatic loading, continuous conveying, controlled heating zones, automatic unloading, and programmable cooling processes, enabling fully automated production without manual material handling.

It is widely used for the brazing of aluminum heat exchangers, cooling plates, condensers, evaporators, stainless steel assemblies, copper components, and high-temperature alloy parts, ensuring consistent joint quality, high productivity, and reduced labor costs.

Our continuous vacuum brazing furnaces are designed to deliver fully automated, non-stop brazing cycles under high-vacuum or controlled protective gas conditions.

Compared with conventional batch furnaces, the continuous system offers automatic loading and unloading functions, allowing workpieces to enter and exit the furnace automatically without manual intervention.

By eliminating oxygen and reactive gases during the heating process, the furnace helps ensure oxidation-free brazing, clean joint surfaces, strong metallurgical bonding, and excellent dimensional consistency.

The equipment can be configured according to product requirements and production capacity, and its applicability is equivalent to that of ordinary high-temperature vacuum brazing furnaces and high-vacuum aluminum brazing furnaces.

Continuous vacuum brazing furnaces are upgrades to standard high-temperature vacuum brazing furnaces or high-vacuum aluminum brazing furnaces, featuring continuous feeding and discharging capabilities. Therefore, their specifications are similar to standard vacuum brazing furnaces, but their performance is superior, making them ideal for high-volume, fully automated production processes.

They utilize nickel-chromium, molybdenum, or graphite alloy heating elements, with a maximum operating temperature of 750℃ or 1300℃, temperature uniformity maintained within ±3℃, and temperature control accuracy of ±1℃. In terms of vacuum performance, the ultimate vacuum is 6×10⁻⁴ Pa, the pressure rise rate is 0.3 Pa/h, and the gas cooling pressure is 2 bar.

We offer standard models in the following sizes:

Effective area dimensions range from 500×500×1600 mm to 500×1600×3000 mm.

For furnace types, production volumes, and other requirements, we can also provide solutions and designs tailored to customer needs.
