Specialty Graphite Crucible For Vacuum Aluminizing Films Production Supplier

Product Name Graphite Crucible for Vacuum Evaporation

Application：Used for aluminum evaporation coating on polyester film. Coated substrates can be BOPET,BONY,BOPP,PE,PVC

Size and Shape：Custom made according to drawing

Material：High purity, low ash content graphite material prevents volatile substances, avoids spots, holes on aluminum coated film.

Advantages：Long service life : continously 48~60hours

Advantages：Produced with special process. High bulk density and low porosity resist erosion of molten aluminum and its gas particles.

We have anti oxidation and anti leakage treatment of graphite material, greatly improves the oxidation resistance of graphite crucible, bulk density, flexural strength and compressive strength, enhanced corrosion resistance, hardness, lower porosity and permeability, greatly weakened the molten aluminum and gaseous aluminum molecular erosion ability and prolong the working life. Quality of graphite crucible for vacuum coating has been greatly improved. The antioxidant, no overflow, no crack, no leakage aluminizing, the evaporation is good, the working life is long, the average furnace reached 18600 meters / roll 50 - 60 furnace, 24000 meters / roll 40 - 50 furnace , the production of 12500 meters/roll, 10000 meters/roll, 9000 meters/roll, 5000 meters/roll, times of furnace have greatly improved.
