Currently Corona Treatment technology includes machines with different systems that achieve the right balance between the materials to be treated and the needs of the customer.
The treatment station, or treatment tower, can support a naked roller system, coated roller system or a universal system. The difference between the systems is on the position of the insulator in the treatment station. In a station with a roller coated the latter is insulated with some type of dielectric material (sleeve) and the electrode is bare metal. In a naked roller system, the latter has no insulation, but the electrode is insulated. In a universal station both the roller and the electrode are insulated.
3D Corona treatment: this is for the treatment of existing components before they need to be coated, printed, glued, or painted etc. Corona treatment is used for its adhesion optimisation properties of the substrate. In this case the treatment station works with rotary electrodes (electrodes mounted on rotating elements), and not with rollers.
