Equipped with one high-power MF induction heating metal filming device, compare with the resistance heating (BN boat or graphite boat) evaporation filming, the most advantage of MF induction type evaporation filming is the aluminum(or other derby)can be co liquated and deaired and form the stable molten pool in the crucible, which can avoid the sudden splash of the drops,futhermore,can get high evaporation rate and even film thickness without burning the plastic film, so the filming has good quality and the pinhole will be less than 1pc/m2,
    The MF induction evaporator source of this series roll coating machines adopts IGBT induction heating technology, the integration control system of the screen and the heating power of each evaporator crucible can be adjusted according to the requirement.
