What are the main advantages of Plasmatreat’s “Openair®“ plasma technology in comparison to other surface treatment methods?
There are many advantages to using Plasmatreat’s Openair® plasma surface
technology. The main advantage is the enormously high efficacy when
compared to other methods for the activation of surfaces. The
Plasmatreat Openair plasma surface treatment technology simply results in better and more
durable surface activation. Plasmatreat’s Openair® plasma systems are
also very easy to integrate into existing production lines, they are
environmentally friendly, space-saving and have low operating costs.
What will you need to run a plasma pretreatment system?
Public current (230V/400V) as well as a compressed-air supply are sufficient. An extraction system is also required.
What are the possible production speeds that can be reached?
The result of the surface treatment depends on the speed of the passing
material, on the effective distance of the nozzle end, and on the width
of the treatment area. Partially, processing speeds of up to 100 m/min
can be reached. When treating EPDM-/ TPE sections, e.g., the speeds run
are about 2 to 30 m/min.
Can original methods (use of solvents) be replaced by the Plasmatreat Openair® plasma technology?
Plasmatreat has demonstrated in many user operations that its Openair®
plasma technology can provide superior surface treatments as activation and cleaning
than the use of solvents and, in many cases, allow users to completely
abandon the use of environmentally damaging substances such as benzene
Why is it that the plasma surface technology works so well for composites?
Normally it is extremely difficult to pre-treat composites because of
the differing electrical and thermal conductivities. In the Plasmatreat
Openair® atmospheric plasma process, low temperature plasma is applied to the
material to be activated allowing superior surface treatment without any
negative effects on composite materials.
Why is it so simple to integrate your plasma systems into production lines?
Plasmatreat’s plasma systems and nozzles require very little space and are easily
installed into existing production lines. We can easily adapt our
pre-treatment stations (plasma nozzles within a protective covering with
extraction) to your individual manufacturing conditions.
What kind of running costs will arise?
The only operation expenses will result from the electricity and
compressed-air consumption, and the ordinary maintenance costs. No
costly operating supplies or other consumables are needed.
Are plasma flames hot?
Plasma is much cooler than other combustion flames (about 300°C). With
most applications, the temperature of the moving material increases by
about 15 °C. The process is cool enough that even fingernails can be
treated using Plasmatreat’s Openair® plasma method.
Does the plasma process produce any toxic emissions?
No ozone is released during the plasma pre-treatment. Nitrogen oxides
and monoxides can be produced when certain materials are pre-treated.
For this reason complete Plasmatreat Openair® plasma surface treatment systems
incorporate an extraction system to remove any such emissions.
Are any special gases required for the Plasmatreat Openair® plasma process?
You need nothing other than electrical energy and oil-free compressed
air. If you do not have a separate compressed-air supply, we can provide
the systems with low-pressure side channel compressors for you.
Is there any risk of an electric shock in the area of the plasma beam?
There is a risk of electric shock directly inside the plasma flame. The
nozzles themselves are grounded and therefore can be directed by hand
without risk of electrical shock.
How long does the activation effect on the surface last?
The length of time that the activation effect will last will vary
depending on the material activated. The effect is strongest directly
after the treatment, then fades gradually and settles at a level higher
than before pre-treatment. Under ideal circumstances production steps
such as coating or painting should be carried out directly after the
pre-treatment. However, activation by Openair® plasma shows an extreme
long-time stability in comparison to other pre-treatment methods. We
would be pleased to discuss with you in detail how the activation effect
will work in your particular application.
What is the distance between the plasma nozzles and the surfaces being treated?
About 1 to 2 cm. The necessary adjustments to achieve the proper
distance are very simple and their use in the production process is
uncomplicated. The components are not subject to mechanical wear and
Is it possible to treat complicated or three-dimensional geometries?
Plasmatreat’s Openair® plasma flames infiltrate into grooves and small
areas. The pre-treatment effect is even intensified in corners. Thus,
you can effectively pre-treat plane surfaces as well as complicated
Does the Plasmatreat Openair® plasma process alter the mass properties of a material?
This process is a plasma surface treatment method where ions react with the material‘s surface. It does not change the mass in any way.
Does any scientific literature on the process exist yet?
The Fraunhofer-Institute in Bremen has attended to this subject.
Relevant literature is available through us. Please send us an email if
you require any further information.
