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 condenses 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 desired coating properties and the high coating purity are particularly noteworthy.
We use three different PVD processes for coating: One is thermal evaporation and the other is sputtering, also known as cathodic sputtering.
Plasma treatment of polymer surfaces in a vacuum can also be carried out in one of the systems. This is used to clean and activate the surface in order to improve the adhesion of paints, adhesives and coatings.
ROWO has three 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.
