For many advanced industries, precision and quality in metal joining are paramount. Vacuum brazing furnaces have emerged as the cutting-edge solution for industries ranging from aerospace and automotive to electronics and medical devices.
Our expertise in vacuum brazing allows us to provide state-of-the-art solutions tailored to your industry. Whether for laboratories furnaces or large-scale industrial processes, our vacuum brazing furnaces guarantee precision, efficiency, and high quality.
Vacuuml brazing is a heat treatment process which consists in joining two metallic items by melting a filler metal used as a joint, such as copper, cobalt or nickel. This metal joining process takes place at high temperature, in a controlled atmosphere or under vacuum, to insure homogeneity and quality of the process. Indeed, a rapid heating up with no overshoot and an atmosphere without oxygen prevent oxydation and ensure the quality of vacuum brazing processes.
There are several advantages when vacuum brazing. It is a profitable process that easily fits in metallic parts‘ production. Also, the dilution of the metal to be joined is low since the filler metal should have a lower melting point than the adjoining metal.
Using a vacuum brazing furnace provides several advantages over traditional brazing methods :
Within ECM Technologies, we apply our vacuum furnaces‘ technology to brazing. Temperature homogeneity and the absence of oxygen ensure the full mechanical integrity of treated parts and of oxidation sensitive assembly at high temperature. Our solutions are nimble enough to adapt to different kinds of atmospheres and required thermal profiles (heating speed, maintaining time, cooling speed, control of overshoots).
Moreover, pieces can be treated by batch, which implies a significant increase of productivity and of profitability.
Finally, we offer solutions with transfer systems that limit moves during the solidification phase. This ensures a treatment of premium quality since it reduces distortions and internal stresses. Moreover, the ECM Technologies’ range fulfills the needs of laboratories as well as of large industrial lines requiring high capacities. This allows ECM Technologies to adapt to various production flows.
Our vacuum brazing furnace provide :
A vacuum brazing furnace operates by creating a vacuum environment that eliminates contaminants such as oxygen and moisture.
Metal parts, along with the appropriate filler metals, are carefully arranged in the furnace chamber. Precise fixturing ensures that components remain in the optimal position during the entire cycle.
The furnace heats the assembly gradually to the target brazing temperature. Advanced control systems prevent temperature overshoots, ensuring that each joint is formed under optimal conditions.
Once the required temperature is reached, the filler metal melts and flows into the joint through capillary action. This results in a strong, uniform bond between the components.
The cooling phase is just as critical as heating. A gradual, controlled cooling process minimizes internal stresses and distortions, resulting in a durable joint that meets the highest quality standards.
Six ranges of products compose ECM Technologies’ vacuum brazing furnace offer to meet different industrial needs :
Our vacuum brazing furnaces are dedicated to brazing under inert gas, hydrogen or vacuum.
