INVENTION MEETS RELIABILITY Vacuum aluminum brazing furnace

Vacuum aluminum brazing has a very narrow range of acceptable process temperatures. As a rule of thumb, the filler metal must liquefy before the base metal reaches VACUUM ALUMINUM BRAZING solidus temperature. In most cases, this temperature Known for years, the VAB technology is gaining in profile and the furnace’s ability to achieve it are critical. importance due to its environmental friendliness and process cleanliness. VAB furnaces provide reliable and repeatable brazing results in a wide range of furnaces tailored to customer expectations and requirements. The VAB furnace with fluxless brazing...

VAB technology is ideal for complex shapes, internal and multi-surface welds, different aluminum grades, and various thicknesses. All aluminum alloys which can be flux-brazed can be vacuum BENEFITS / Oxygen-free brazing eliminates the cost of flux and its application / Parts washing limited to pre-process washing / After the process, the parts are clean with a dull gray finish brazed. In addition, some magnesium-containing aluminum alloys (e.g. 5xxx series) which are not easily flux-brazed can be vacuum brazed. Using the correct techniques, the alloys of the lxxx, 3xxx, 5xxx, 6xxx and 7xxx series...

Batch VAB dedicated to the aerospace industry and commercial processing, with the batch loads configured on trays This product is used for larger heat exchangers and longer aluminum brazing processes. VAB TECHNOLOGY PRODUCTS ARE DIVIDED INTO 3 TYPES: VAB multi-chamber - continous line This type of furnace is dedicated to those who expect the highest efficiency and shortest brazing time. Due to the large number of chambers, it is possible to shorten the brazing time several times over. The VAB multi-chamber furnace is a modular and flexible solution which can be adapted to special needs, in particular...

Vacuum furnace for oil removal A vacuum oil separating system is used to remove oil remaining from the part forming or stamping process. It is performed before further heat treatment, most often brazing. This operation is necessary to ensure the proper cleanliness of the parts before the brazing process. Oil removal involves heating the parts to the oil evaporation temperature in underpressure. The temperature in the furnace is controlled using a multi-zone heating system, which allows precise control and regulation of the temperature. A specially designed pumping system removes oil vapors from...
