Difference between untreated and plasma treated part    Plasma Activation
Process Description

Surfaces of plastic parts can be changed significantly in their properties by plasma treatments:

The surface tension can be reduced (plasma activition) to achieve a better wettability. By this a considerable improvement for a painting, printing or bonding will be reached.

The remove of coatings or the cleaning of plastic parts with a plasma process is possible (plasma etching). Such prepared plastic parts are clean and wettable excellently.


The plasma technology has a lot of advantages compared to other surface technologies:

    pollution free, because no toxic media are used or produced by the processes
    reproducible results by the use of free programmable computers
    automatic handling and integration in the production cycle possible

     and due to no use of acids etc


In the vacuum chamber the plasma is created by electric fields. By this gas molecules and atoms will be ionised and they will influence the plastic surface. By the addition of small amounts of special process gases the surfaces will be influenced specifically. The plasma for the treatment of plastics will be produced by microwaves or high-frequent alternating voltages. Compared to this a pulsed dc plasma is used normally.


With the plasma technology as a key technology for different areas, new fields will be opend. The use of these technologies is increasing especially for compound materials like plastic, metals and ceramics.
