The pre-treatment of free-form parts and other three-dimensional objects made of plastic presents a particular challenge. With Arcojet® plasma generators, however, surface activation succeeds reliably and to a consistently high quality. This enables you to create optimal bonding conditions for paints, varnishes and adhesives.
The plasma generators of the Arcojet® series are ideally suited for the pre-treatment of small plastic parts such as moulded parts, profiles, cups and tubes. They achieve a treatment speed of up to about 15 m/min.
The plasma generator can be controlled by a higher-level system without any problems, as all signal inputs and outputs are connected to industry-standard connectors. Thanks to different head designs, the Arcojet® is suitable for any installation situation.
Plasma treatment in cycle or manual mode is also possible with these plasma generators. For this purpose, we offer an insulating handle for safe operation and special guide rollers that guarantee a constant distance of the electrode head to the substrate.

The Arcojet® PG051 is equipped with an electrode head that covers treatment widths of up to 55 mm. Larger working widths can also be realised by means of a battery arrangement. Feel free to ask us about it.
The Arcojet® PG052 has two free-radiating electrodes that can be controlled separately. This feature allows the user to use the plasma generator on two production lines at the same time or to use it for a wider working width.
Plasma activation is now the method of choice when it comes to the surface pre-treatment of polymers. The Arcojet® plasma generators combine reliable plasma generators with modern electrodes and can be individually adapted to your needs. They also offer all the benefits of plasma treatment at atmospheric pressure.
In contrast to low-pressure plasma generators, the Arcojet® does not require a vacuum chamber and can therefore be integrated directly into in-line production. Since plasma devices do not require an earthed counter electrode, they are particularly suitable for the surface treatment of three-dimensional objects such as plastic profiles, moulded parts or cups.
In addition, a plasma generator, like all physical surface activation procedures, eliminates the need for wet chemical primers. The time required to apply and dry these substances is no longer required. In addition, there are no hazardous waste materials that would have to be disposed of at great cost.
The surface activation of polymers is the most important application area of plasma activation today. These plastics have a polar, hydrophobic surface when not activated. This is why coatings and adhesives adhere poorly to them. If you want to paint PP plastic, for example, this is very difficult to do without plasma pre-treatment. Only plasma activation increases the wettability of the substrate to such an extent that coatings adhere permanently to it.
But how does activation with a plasma device actually work? Plasma generators use a high-frequency cell to activate a process gas by ionising it with high voltage. The gas is influenced by heating and electric fields in such a way that its molecules release free electrons and ions into the ambient air.
In atmospheric devices, the process gas is usually compressed air, which is used to blow the plasma out of the nozzle onto the substrate. However, the compressed air can also be supplemented or replaced with other process gases.
