Vacuum Coating
PVD methods We extend your material properties

The physical vapor deposition processes are vacuum-based coating processes in which the coating material is transferred into the gas phase with the aid of physical processes and then condensed as a thin layer on the substrate.

Vacuum coating processes are characterized by a number of advantages, of which the variety of possible coating materials, the reproducibility of the coating properties, the targeted adjustment of the desired coating properties and the high layer purity are to be emphasized.

We use two different PVD processes for the coating: One is thermal evaporation and the other is sputtering, also known as cathode sputtering.

Plasma treatment of polymer surfaces in a vacuum can also be carried out in one of the systems. This allows the surface to be cleaned and activated in order to improve the adhesion of paints, adhesives and coatings.

ROWO has two coating systems available for coating flexible substrates from roll to roll in vacuum.

Rolls up to a width of 1,650 mm and a maximum roll diameter of 1,200 mm can be coated.

The material can be wound on cores with a diameter of 76, 120 or 152 mm.

The coated material can be cut to the desired width and length with two modern slitter rewinders.
