An example of the high efficiency of Openair® plasma activation is the manufacture of pre-coated sheet metal (coil coating). This material is needed in the industrial production of household appliances and in the automotive industry.
In the coil coating process, strip metal is provided with a surface coating or varnishing to achieve optimum protection against corrosion and to simplify subsequent production processes. For long-term layer and varnish adhesion, the aluminum strip must first be completely cleaned of rolling oils in an ultrafine cleaning process.
Openair® plasma removes all residues reliably and efficiently while activating the material surface for optimal adhesion and a flawless finish. The Openair® plasma treatment can be integrated inline directly upstream of the coating station in the rolling mill.
Moreover, the dry plasma process is particularly environmentally friendly. The large amounts of chemicals that would otherwise be required for ultrafine cleaning are omitted entirely.
Also, the time- and energy-intensive drying processes necessary in wet chemical treatment are no longer required.

Plasmatreat constantly faces shifting demands as a result of new ideas, regulations, and standards. Customers are increasingly approaching the company with unique and innovative project requests. Consequently, the capacities of the technology and research center will now be expanded to include a class-6 cleanroom.
Plasmatreat supports digitized manufacturing with its Plasma Control Unit (PCU) and makes numerous controls, regulation, and monitoring functions available to ensure consistently high surface-treatment quality and reproducibility.
VOCs occur when solvents and solvent-containing products are used, and they are harmful to the environment. Nevertheless, manufacturing in many industries still involves pre-treating surfaces with primers, bonding agents or other chemicals that release VOCs. With its Openair-Plasma process, Plasmatreat offers an environmentally friendly alternative.
In addition to the Openair-Plasma Systems for surface treatment Plasmatreat GmbH also offers individual production cells with automated solutions to ensure seamless integration in the production lines. Plasma Treatment Units (PTU) are tailored to the customer's technical processes and are equipped with various operating options. Here Plasmatreat offers the solution of coordinated process automation combining efficient surface treatment and a perfectly coordinated handling of assemblies and components.
Plasmatreat plans to get more involved in the disinfection industry by providing solutions for disinfecting protective clothing during the current corona crisis.
