The VAB chamber furnace is a specialized device designed for the vacuum brazing of aluminum. It employs an effective and efficient technology known as no-flux technology. This approach ensures environmental safety and allows for reproducible results. The VAB furnace line is tailored for semi-continuous or batch production of aluminum components, primarily catering to the automotive and aerospace industries.
Vacuum fluxless brazing provides the advantage of eliminating flux inclusions and designing blind cavities, winding paths, and small transitions in brazed parts. This holds true without encountering the detrimental effects associated with flux removal and flux entrapment after the brazing process.
Benefits:
/ Uniform Temperature Distribution,
/ Consistent Results and Minimization of Non-conforming Products,
/ Easy Loading,
/ Can Be Integrated with Other Equipment (De-oiler),
/ Part Purity/No Oxidation.
Materials:
/ All aluminum alloys that can be brazed with flux can be vacuum brazed. Additionally, some magnesium-containing aluminum alloys (e.g., the 5xxx series), which are not easily brazed using flux, can be vacuum brazed.
/ By employing proper techniques, alloys from the lxxx, 3xxx, 5xxx, and 7xxx series can be vacuum brazed.
