All four of our vacuum coating machines are able to evaporate aluminium onto a range of substrates. The thickness of coating can be varied depending upon application and end requirements. High purity aluminium wire is fed onto ceramic boats located across the film width with the boat temperature maintained between 1300◦C – 1500◦C.
Aluminium vaporises from the surface of the liquid pool and condenses onto the substrate, which is supported on a cooled drum. Automatic deposition control system maintains coating uniformity for a precision finish. Three of our four vacuum coating machines can also provide plasma treatment where required.
