Vacuum evaporation method (referred to as vacuum evaporation) is to heat the raw material to be formed in the evaporator in a vacuum chamber, so that the atoms or molecules are vaporized and escaped from the surface to form a vapor flow, which is incident on the surface of the substrate and condenses to form a solid state. thin film method. Since the main physical process of the vacuum evaporation method is produced by heating and evaporating the material, it is also called the thermal evaporation method.
Graphite crucible for vacuum coating of gasification aluminum is mainly suitable for under the condition of vacuum, the metal aluminum gasification and evaporation on the surface of CPP, PET, BOPP film, And forming aluminum composite film. Graphite crucibles are a large number of consumption parts during the producing process, the quality of graphite crucibles will directly affect the product quality and production cost of aluminum plating film.
Al Evaporation crucible is our decades years research results. after three generations, now our crucibles can be guaranteed:
1) Non accumulated scrap to the lip;
2) No cracking,
3) Non hard membrane form on the surface which affect gasfication effect.
4) Very slow oxidation rate, and good performance on evaperation.
