Product Description
Aluminum brazing furnace is an industrial equipment for high-temperature production, with a maximum design temperature of 750 ℃ and a normal operating temperature of 620-630 ℃. It uses high temperature to melt and cool aluminum materials, thereby achieving welding of multiple complex structural parts.
During the brazing process, it needs to be carried out in a vacuum environment or in a nitrogen protected environment, otherwise the aluminum material will be oxidized and have welding defects when exposed to air.
Due to the particularity of aluminum materials, they are widely use in modern industry. The shape and structure of industrial aluminum parts are becoming increasingly complex, and ordinary welding processes cannot meet their requirements. Therefore, aluminum brazing furnaces play an increasingly important role in modern industrial production.
Especially for factories that produce aluminum products on a large scale, as well as large-sized and structurally complex parts, they must have this furnace involved in welding, otherwise they cannot meet the welding process requirements.
Types of aluminum brazing furnaces
Vacuum aluminum brazing furnace
This is a furnace for welding aluminum parts in a vacuum environment. It usually adopts a horizontal structure and a side opening furnace door design. There is a dedicated forklift outside the furnace to smoothly place the product into the furnace.
Aluminum products that are welding do not require the application of soldering flux and do not require inert gas protection during the welding process.
This kind of vacuum furnace can control the temperature and heating time programmatically, so it is very suitable for producing heavy plate and bar heat exchangers, or laminated coolers.
This is an atmosphere protection brazing furnace, which uses chains to transport aluminum products to achieve continuous mass production. It is suitable for the production of lightweight products, such as radiator for automobile engines, condenser and evaporators for automobile air conditioning systems, etc.
By increasing the length of the brazing furnace, it can also produce large-sized products, such as battery cooling plates, industrial microchannel condenser, and liquid cooled gearbox shells.
This brazing furnace is characteristic by full automatic production, and large-scale production can reduce production costs. It is very suitable for oem factories that need large-scale production.
Continuous aluminum brazing furnace
Box-type brazing furnace
This is a box type structural design, but it does not have a vacuum environment and requires nitrogen gas to participate in protecting the aluminum material during high-temperature welding. It can produce various complex parts.
The welding quality of the furnace is the same as that of the vacuum furnace, but aluminum materials need to be spray with flux. Compared with the vacuum furnace, it adds a production process, which may increase some labor costs.
A complete welding process takes about 3-4 hours, so this type of furnace is only suitable for small-scale production factories, but its price is the most competitive.

How to choose an aluminum brazing furnace
Choosing a correct aluminum brazing furnace is a very important thing for a factory. Different types of brazing furnace have the same welding structure, but their prices and effects are very different. Therefore, the following issues must be considered when selecting it
- Does the brazing furnace you selected meet the size of your product and the production output requirements, for example, if the overall size of your product is 800 * 800mm, then the working size of the furnace you selected must be greater than 800 * 800mm, otherwise the product cannot be put into the brazing furnace
- Due to the significant differences in the shape and size of aluminum parts, there may be some variations in production processes and temperature control. You must consider whether the brazing furnace can meet your production requirements
- The output of the new factory may not be large at the beginning. You need to fully consider the output growth in the next 3-5 years, because the service life of a brazing furnace is 10-15 years. You need to consider the output of the factory in the future,
- The overall dimension of the continuous brazing furnace is usually more than 38 meters. You need to check the area of your factory. If you book a brazing furnace and find that your factory is too small to accommodate it, it will cause great losses,
- Power supply is also one of the problems you must consider. Electric heating needs to consume a lot of electricity. You need to install sufficient transformers for your factory to provide stable power for the brazing furnace
