Gleichmäßiger Auftrag feinster Funktionsschichten
Due to the special pressure conditions arising in the vacuum, a wide variety of materials can be provided with wafer-thin – mostly metallic – layers in the thin-film process. This includes, among other things, the vacuum coating of special glasses, displays, flat screens, photovoltaics and special films.
Coated foils are of great importance - for example in the food industry - as capacitor, solar or transformer foils. So-called roll-to-roll systems are used to produce them.
The couplings of the Semiflex range, made of appropriate steel and specially customised for vacuum technology, operate in these systems.
An important feature of the Semiflex couplings which are used in these systems is that, despite displacement compensation, permanent sync is guaranteed, which is essential to evenly apply micro- to nano-thin functional layers.
