This kind of graphite crucible is specially used for aluminum coated film production under vacuum condition.
Quality of graphite crucible will greatly affect film quality and production cost.

Vaccum evaporation aluminum coating is a process under vacuum condition to coat aluminum onto film substrates to form a composite film. Such substrates as BOPET、BONY、BOPP、PE、PVC, direct evaporation aluminum coating process is usually applied, while substrate as paper, leather, evaporation coating and transferring process usually applied.
The vacuum evaporation aluminum coating process requires high quality graphite crucible, and we are capable of stable and quality supplying.

During aluminum and aluminum alloy smelting, hydrogen produced by chemical action with steam diffuse in molten aluminum, which will cause inner structural defect to aluminum products. In order to avoid such defect, most aluminum factories apply dissolved gas floating method to purify molten aluminum. i.e. inert gases such as nitrogen, argon is injected into molten aluminum, and hydrogen will be brought to molten aluminum surface with spread and rise of inert gas.

Rotor and shaft set is necessary to inject inert gas and stir for degassing regarding both intermittent and continuous online degassing methods. Because of properties of heat-resistance, anti-oxidation, high strength and non- infiltration, graphite becomes the optimal choice for material of rotor and shaft, which is named graphite rotor/impeller and shaft set.

Graphite crucible, graphite boat/dish and graphite ingot are widely used in industries of non-ferrous metal, precious metal, industrial furnaces, mould, glass, rare earth, photovoltaic, chemical analysis and other industries.
