Special designed for brazing

It is possible to braze in the clean environment, even
in thee batch-type furnace by adopting metal reflector
and metal heater method. In addition, adoption of gas fan cooling shortens cycletime
and that makes to improve productivity due to
rapid take-out after brazing.

NVF-600B

真空熱処理炉  NVF-600B

Designed for continuous brazing operation, this type of furnace usually consists of 2 to 6 chambers depending on the intended application.
Brazing process is done in better conditions to keep clean inside heating chamber by multi-chamber. A furnace can be tailor-made to suit your specific needs in terms of applications and production requirements.

Compared to normal vacuum furnace, thermal insulation material and heating element areselected from graphite and molybdenum.
It is possible to do high vacuum treatment under carbonless depending on the intended use.
In addition, it can prevent evaporation of brazing filler metal and improve zygosity by introducing partial gas when heated. N2, H2 and Ar gas are also the options of gases.
