Audited Supplier The special graphite crucible for vaporized aluminum vacuum coating is mainly used in the production process of forming aluminum composite films by vaporizing metallic aluminum and evaporating it on the surface of CPP, PET, BOPP and other film substrates under vacuum conditions. A large number of consumable parts must be used in the production process. The performance and quality of the graphite crucible determines its service life and will directly affect the product quality and production cost of the aluminized film.
> It adopts special technology with high bulk density, and low porosity to resist erosion of hot (molten) aluminum and gas- particles.
> Graphite material with high purity and low ash, it can prevent volatile substances, and avoid some spots on coating aluminum film.
> Graphite crucible has good service life performance, it troughs a special coating, and oxidation treatment.
> Graphite crucible is made by final machining, the surface looks like mirror.

In order to protect the glaze layer of the crucible, handling crucible must be very careful, to avoid knocking, collision or falling, we can't put the crucible on the ground and rolling to transport. Once the glaze layer of crucible is damaged, it will lead to oxidation and aging of crucible easily in the process of use. The crucible should be handled carefully in a padded cart (or other suitable conveyer).
Our company use rope, rubber, moisture-proof plastic paper, shockproof to pack the crucible, and according to customers' needs, we can customize wooden cases, export packaging cartons, paper tubes, etc., to ensure that the crucible wouldn't be damaged in transit.
