FEATURES &
ADVANTAGES

Openair-Plasma^® technology compared to other pretreatment processes

High process reliability: Openair-Plasma^® technology is distinguished by high fail-safety and process reliability.
High cost-effectiveness: High process speed, even in multi-shift operation, and lower scrap rates provide high process efficiency. Because it allows for flexible material selection, the Openair-Plasma^® process also facilitates the use of more advantageous materials.
High degree of activation: Unlike corona treatment, Openair-Plasma^® permits a high degree of activation of the surfaces to be treated.
Large process window: Openair-Plasma^® permits a large process window: The danger of thermal component damage is extremely low in comparison to flaming.
Easy to integrate: In contrast to mechanical processes, like roughening and sand or aluminum oxide blasting, Openair-Plasma^® can easily be integrated inline in existing processes.
Environmentally friendly: The Openair-Plasma^® process makes it possible to treat surfaces with solvent-free and VOC-free methods. Unlike electrochemical processes, such as galvanizing or galvanically-supported pickling and chrome plating, wet chemistry is not required.

Interesting Applications for Surface Modifications

Surface Activation

Pretreating different plastics with plasma can also change their surface properties. When in contact with plasma, the mostly non-polar plastics acquire oxygen- and nitrogen-containing groups.

Plasma Coating

Another field of application for plasma technology is the production of ultra-thin coatings on surfaces. An organo-silicon compound is added to the plasma as a precursor and deposited on the material surface.

Plasma Cleaning

Microfine cleaning with plasma can remove the smallest dust particles from the substrate. Precisely defined surfaces with the best prerequisites for further processing are created thanks to the chemical-physical reaction in the nano range.

Plasma Reduction

Oxide layers on metal surfaces can pose challenges in processes like soldering and bonding. The REDOX^®-Tool, an innovation within the Openair-Plasma^® suite, offers an inline solution for oxide reduction. By utilizing atmospheric pressure plasma, this tool efficiently reduces metal oxides, eliminating the need for traditional fluxes and enabling flux-free soldering processes.
