News in corona treatment

Ferrarini & Benelli, a leading designer and producer of corona treatment plants, presents at K 2013 with a positive trend of order collection in the last half year under its belt, launching various new products.

These include a plasma treatment system that finds use in PEX and hollow pipes extrusion and in injection moulding production of plastic components destined for various sectors (including cosmetics). A plasma discharge nozzle makes this system capable of treating small three-dimensional surfaces, in addition to those with high thickness. The effect obtained is enhanced polymer surface energy and better adhesion in inks, adhesives and coating.

Two proposals for extrusion. Ferrarini & Benelli also illustrated a control software for corona treatment developed in order to monitor and certify production. It enables importing to a PC data relating to the functioning of the corona treatment, memorizing them, displaying them and processing graphics and process quality certificates. This program will prove extremely useful to whoever needs to issue quality certificates to their customers, and more generally, whoever wishes to obtain products with a high quality standard.
Also for extrusion, the Lombard company (based in Romanengo, CR) proposes the Bikappa Rotary treatment station, which features remarkable accessibility to the electrode group. This makes for easy webbing of the material and enables quick maintenance and cleaning operations. The electrode group also guarantees constant temperature stability and air gap (distance between electrodes and discharge roller, Editor’s note) along the entire width of the material; it can also be adjusted externally or removed for quick and accurate maintenance.
All these features guarantee the station’s ease of use and high performance surface treatment.

Dedicated to converters and laboratories. Ferrarini & Benelli also present the latest and most powerful version of the universal discharge station Polimetal Kappa Plus, for processing plastic and metalized materials, setting up a “Corona corner” dedicated to lab applications, which are increasingly being requested by customers pursuing constant research and development on materials and processes.
