Graphite crucible for vacuum evaporation

The graphite crucible for vacuum evaporation is mainly applied to the aluminium evaporation gasification on CPP, PET, BOPP in vacuum to produce aluminum composite foil. The quality of graphite crucible can affect the working life and directly affect the production cost of aluminum foil and its quality.

The density of graphite crucible reaches 1.9g/cm3. We have the anti-oxidation and anti-permeation treatment on the crucible to improve the oxidation resistance, bulk density, hardness and corrosion resistance of the graphite crucible and reduce porosity and permeability. Advantages of our crucible: Anti-oxidation, no cracking, no penetration, good evaporation effect
