Under what circumstances would you choose a vacuum brazing furnace?

When brazing a product, in addition to brazing materials, it is also particularly important to choose a brazing process that suits you.

In addition to the common flame brazing, brazing furnace, etc., there is also a vacuum furnace brazing, which is divided into vacuum furnace and nitrogen protection furnace according to the degree of vacuum in the vacuum furnace. The role of nitrogen protection is to reduce the air composition in the furnace and improve the vacuum. degrees, but the cost of nitrogen is lower, so it is more popular.

The characteristics of vacuum furnace brazing are relatively obvious. The advantage is that the air content in the skull is very low, the product will not be oxidized during the brazing process, and the product is heated evenly, and the brazing appearance is also good. The disadvantage is that the price of the equipment itself is relatively expensive, and the heating time of a product for brazing is long, and the overall cost is high and the efficiency is low.

All in all, vacuum furnace brazing is suitable for products with relatively complex design, high brazing difficulty and high product value.
