Machine Introduction
An aluminum brazing furnace welds multiple structurally complex aluminum parts, usually in an inert gas-shielded environment for brazing. It is widely used in automotive radiators, condensers, plate-fin heat exchangers, etc.
This brazing furnace has multiple devices with different functions connected to a production line, achieving an automated continuous production mode and low production costs.
With the continuous development of industry, the control system of this aluminum brazing furnace has update to intelligence. It can be operated through programmed preset steps, and engineers can also remotely obtain its operating parameters and all details.
Aluminum brazing furnace advantage
1. MAFU uses 10 mm-thick stainless steel 316L as the raw material. This material ensures good temperature stability and has a service life of over 15 years.
2. Thermocouples collect the temperature inside the furnace, convert it into digital signals, and send them to the control system to achieve precise temperature control and ensure temperature uniformity.
3. This aluminum brazing furnace can weld complex, structured products, such as aluminum radiators, battery cooling plates, oil coolers, and plate heat exchangers.
4. Compared to competitors’ brazing furnaces, The latest manufacturing technology saves 22% electricity, 45% nitrogen, and 18% natural gas.
Aluminum brazing furnace technical details
Temperature control
Mastering aluminum brazing technology proficiently is a complex process. We have upgraded the temperature control system to simplify the entire operation process for users, allowing even novice engineers to master this technology quickly and easily.
Divide temperature zones
We divide the aluminum brazing furnace into multiple temperature zones and independently control each temperature. This method has the advantage that the temperature difference in one zone does not affect the brazing quality.
Upgrade temperature control switch
The current temperature control is all digitized, with a PLC centralized control. This intelligent control ensures good temperature uniformity.
Average temperature configured
Usually, we configure two average-temperature thermocouples to check the average temperature inside the brazing furnace. This gives engineers valuable data and ensures aluminum products’ quality and smooth output.

Aluminum brazing flux spraying
This process is necessary for high-quality welding; almost all aluminum parts must be coated with brazing flux. Our brazing furnace has this equipment, and it sprays fully automatically. Excess brazing flux can be reused.
Our brazing furnace has two flux tanks, one for spraying the surface of the aluminum core and the other for spraying the header plate of the aluminum core. The two flux tanks contain two different concentrations of flux. This is crucial for ensuring the quality of the aluminum radiator core and can effectively reduce the leakage of the aluminum core.
After the flux spraying, the core passes through an air duct. The strong wind pressure blows away the excess moisture, making the aluminum core easier to dry. This process is fully automated.
Please note that the spraying process for producing battery cooling plates is different, and it cannot be shared with the spraying equipment for radiators and condensers.
Optional configuration of aluminum brazing furnace
The atmosphere detection system is constantly monitoring the internal oxygen ratio. If the oxygen ratio is too high, the control system will issue a warning, giving engineers enough time to respond quickly and deal with this emergency.
This is one of the effective ways to provide quality, preventing human errors from causing large-scale quality defects.
This oxygen analysis system is an optional configuration. Some small factories may choose not to use it due to cost considerations.
