Vacuum Brazing Furnace Manufacturer

Therelek Vacuum Brazing Furnace has curbed out an unparalleled place in the global market for itself in terms of carrying out a seamless process of joining multiple faulted parts of similar or dissimilar materials (traditionally metals, yet used with ceramics); by melting and filling some filler materials into the gaps. 


It is a well-established fact by now that these Therelek vacuum brazing furnaces are competent enough to handle the various melting points of the different materials that are being used in them for various engineering processes; as it is the filler metal or ceramic must have a lower melting point than the adjoining parts and by heating the joint to a temperature above the liquidus temperature of the filler, yet somehow below the solidus temperature of the parent materials, a strong joint is achieved.

Therelek vacuum brazing furnaces are at an advantageous position as compared to normal vacuum furnaces. Let’s have a quick look on them:

-Perfectly brazed joints that are free of oxides.

-Ability to perform multiple joints at one go. 

-Ability to bring together different materials e.g. ceramic to other metal.

-Reducing the residual stress by controlling accurately every stage of the heating and cooling cycles.

-Maintaining temperature uniformity and hence gaining minimal distortion or movement, which is desired for assemblies of fine finish. 

-Cost-effective and time-saving due to parallel running of heat-treatments like hardening or annealing of the parts in a single furnace thermal cycle along with carrying out metal-joining processes.
