Vacuum Brazing Furnace

Vacuum Brazing Furnace is a process that produces high-quality joints in a vacuum atmosphere at temperatures of approximately 750°C to 1350°C. This also allows the joining of different materials such as ceramics and steel. This also allows the joining of different materials, such as ceramics and steel.

High-Temperature Vacuum Brazing Furnace,  Molybdenum Chamber up to 1350℃

High-temperature Vacuum Brazing Furnace can reach 1350℃, suitable for stainless steel, CBN tools, and Diamond tools brazing in the vacuum environment. Due to its high vacuum and high temperature, it can also be used for sintering and heat treatment of other workpieces.

A typical vacuum brazing process is as follows:

Cleaning of the parts to be brazed
Brazing (foil, wire, solder paste, powder, plating) and assembly of the product
Setting up of the parts on the furnace rack
Furnace process (controlled by microprocessor)
Unpacking and cosmetic inspection
Testing / final inspection
 

The following aspects play an important role:

Cleaning of the parts to be brazed
Availability of the clean assembly room
Use of high vacuum ovens
Process variables
Loading tools
Testing facilities

The most important properties of vacuum-brazed joints are as follows:

Very strong and reproducible joints. Equal to or even stronger than the base material.
Corrosion-resistant joints are formed by using valuable brazing materials.
Joints may be exposed to relatively high temperatures (< 750 ºC)
Cleaning process. The product remains metal blank.
Flux-free brazing. Therefore, no undesirable surface reactions.
Very clean and hygienic gapless joints. Important for the food or medical industry.
Vacuum-sealed/leak-proof joints.
Various materials can be joined to each other (e.g., metal-ceramics).
Can be brazed and hardened in one process.
Parts can be hardened in almost all processes after brazing treatment.
High degree of construction freedom; can be thick/thin and can join large surfaces.
Multiple joints can be created in one process. Complex products can be created
A high degree of dimensional stability is possible, with no or almost no deformation
