Often, materials used in the manufacturing sector need to have particular surface characteristics. Plasma treatment cleans and activates plastics, cardboard and metals. Plasma can be defined as the 4 th state of matter, after solid, liquid and gas. Administering energy to a gaseous matter, through an electric discharge, the gas turns into plasma.

This principle of physics is the basis of the plasma treatment that, by striking the surface to be treated via nozzles, changes the surface energy. Hot plasma, around a thousand degrees, is used in the metal and ceramics industry.

Cold plasma is useful for processing very delicate materials such as plastic, paper and integrated circuits. Plasma generated at normal atmospheric pressure can be integrated in-line and results in better adhesion and resistance of the treated surfaces. It promotes the application of inks, paints, adhesives and coatings, eliminating release agents and additives, confers greater resistance to corrosive agents Plasma is created inside the nozzle between two electrodes. One or more nozzles are linked to the generator through a screened cable with a pressure gauge.

Surface modification can be adjusted by varying the input power, modulation frequency of the electric field, nature and pressure of the supply gas, the temperature and the position of the substrate. Compressed air is not necessary. To treat small areas of aluminium foil and plastic, to promote adhesion of glues used in the production of plastic boxes fold-and-glue lines ; prepare the boxes for subsequent phases of production gluing, printing, foiling ; to improve the adhesion of printing inks, coatings and paints even on difficult surfaces.

To treat dashboards, bumpers, improve the anchoring of motor vehicle door seals, improve structural bonding and painting of motorcycle and truck parts, to give the surface anti corrosion properties. To prepare displays for scratch resistant treatment; optimize the production of semiconductors; paint mobile telephone casings without using volatile organic compounds VOCs.

To coat profiles and seal the edges of panels for furniture; optimize bonding of appliance parts, paint plastic toys using non-toxic colors. In Air Corona allows the treatment of non-conductive materials: three-dimensional plastic objects or small areas of two-dimensional plastic surfaces and also conductive materials: parts or metallic components.

Three types of plasma treatments exist: atmospheric pressure the most innovative and economical low pressure vacuum which needs separate chamber and evacuation pump high pressure unsuitable for surface treatments Plasma generated at normal atmospheric pressure can be integrated in-line and results in better adhesion and resistance of the treated surfaces.
