Public current (230V/400V) as well as a compressed-air supply are sufficient. An extraction system is also required.

Yes, it can. It is used often for solar cells, automotive sunroofs and windshields.

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 400 m/min can be reached. When treating EPDM-/ TPE sections, e.g., the speeds run are about 2 to 30 m/min.

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 or acetone.

Sandblasting can remove oxides and contaminants. But if it is a structurally thin material, there is a concern that you are removing some of the substrate by sandblasting. The other concern is all the sand that needs to be safely captured when done with the process.

Sandblasting can clean a surface. But it cannot activate a surface. It will not improve wettability or introduce oxygen into the surface which creates hydroxyl groups that will allow the adhesive to form a more complex covalent bond.

Surface chemistry is extremely important when dealing with adhesives, bonding and thermal transfer.

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.

By using plasma treatment certain material combinations are possible that might not have been feasible otherwise. This expands the range of materials that can be used, offering engineers more flexibility in design and material choices.

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.

78 db – close to the industry standard for hearing protection. The jet usually is housed in a robotic cell which can lessen the noise.

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.

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.

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.

By removing contaminants, and changing the molecular structure of the surface (i.e. eliminating the peaks and valleys), it increases the wettability of the thermal adhesive so more surface contact can be made. Therefore, the cell and the cooling plate are in full contact and air gaps or bubbles (which trap heat) are eliminated.

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.

No, not unless there was something extreme on the surface (i.e. axle grease). Machining oil or stamping oil is fine. The idea behind the use of plasma is to avoid using any kind of chemicals or VOCs.

By itself, Openair-Plasma® will clean and activate a surface. To protect against corrosion, our PlasmaPlus® AntiCorr® technology will coat the surface with a thin, vitreous, glass-like layer that will stop the ingress of salt through the oxide layer.

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.

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.

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 tear.

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 shapes.

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.
