Compact design for easy integration
The PlasmaBeam OEM systems can be reliably installed and produce a plasma flame of the same, tried-and-tested quality as our benchtop units from Diener electronic.
Atmospheric pressure plasma offers a wide range of applications. The units are primarily designed for the local pre-treatment of a wide variety of surfaces, for example for cleaning and activating polymers, metals, ceramics, glass and hybrid materials. Thanks to the unique design of the PlasmaBeam OEM from Diener electronic, the plasma system can be easily integrated.
The atmospheric plasma processor for surface cleaning and activation is used in many industrial sectors, e.g. in plastics engineering, the automotive industry, electrical engineering, elastomer technology, precision engineering, medical technology, solar cell technology, as well as semiconductor technology and optics.
Cleaning
The Atmospheric pressure plasma system PlasmaBeam OEM offers a wide range of applications for the local ultra-fine cleaning of polymers, metals, ceramics and glass. This process breaks down molecular residues of contamination.
More information
Activation
Atmospheric pressure plasma is a highly efficient process for locally improving the adhesion of various substrates prior to painting, gluing, printing or bonding. Plasma activation using the Atmospheric pressure plasma PlasmaBeam OEM system creates polar bonding partners and increases the surface energy.
The STANDARD nozzle on the plasma generator
The principle of the atmospheric plasma system PlasmaBeam OEM comprises the basic components: the power supply unit and the plasma generator. The plasma generator receives the high-voltage and process gas supplies from the power supply unit via a supply line. An arc discharge is initiated between the high-voltage electrodes in the plasma generator. The plasma generated is emitted via the STANDARD plasma nozzle.
The PlasmaBeam OEM from Diener electronic is fitted with the standard plasma generator. The plasma nozzle achieves a treatment width of approx. 8–12 mm at high speed – ideal for activating the adhesive joint prior to bonding.
To ensure effective surface treatment with atmospheric plasma systems, it is important to note the following: the treatment must always be carried out whilst the workpiece is in motion!
Targeted, partial surface activation using PlasmaBeam
Atmospheric pressure plasma is a technical plasma that is excited at normal ambient pressure. The process gas is usually purified, dry compressed air, although pure oxygen or nitrogen may also be used. Excitation is achieved via a high-voltage gas discharge. Due to the short mean free path of the particles at atmospheric pressure, the plasma is spatially confined.
Consequently, the atmospheric pressure plasma in the PlasmaBeam OEM from Diener electronic is always partial, enabling targeted activation of the surface exactly where it is required.
Remote connection – SUB-D connector
The Atmosphärendruck plasma systems PlasmaBeam OEM can be controlled via the remote connection. The external PC control system for your production plant can activate the plasma ON/OFF function and read the system status (‘Plasma ON / OFF / Ready’).
Mounting the STANDARD plasma generator
As either the workpiece being processed or the plasma generator is in motion, the plasma generator must be permanently installed. On request, Diener electronic supplies task-specific mountings for the PlasmaBeam OEM to ensure the plasma generator is securely fixed in place.
Free of Volatile Organic Compounds
Plasma surface treatment is the key approach to VOC-free (Volatile Organic Compounds) manufacturing. It enables the functionalisation of components without the use of wet chemical processes such as solvents or primers. The environmentally harmful use of chemicals, rinse water and drying times is virtually eliminated, thereby conserving resources. Thanks to the process stability, the scrap rate can be reduced, which also contributes to the principle of sustainability.

FAQ Frequently Asked Questions
What are the main benefits of activation using atmospheric pressure plasma?
PlasmaBeam technology is suitable for in-line processes, e.g. plasma activation of continuous rubber profiles and hoses prior to printing, bonding, flocking or coating.
This technology is suitable for use with robots, i.e. the 2- or 3-dimensional surfaces can be scanned with the plasma beam using robots.
PlasmaBeam enables localised surface activation without the need for masking – the remaining surface areas are not affected.
What is the treatment range for the PlasmaBeam OEM systems?
The treatment width for the PlasmaBeam OEM systems from Diener electronic is between approx. 8–12 mm per nozzle. However, the cleaning width must be checked in advance for each application (e.g. by measuring the contact angle). When using pure oxygen (O₂) or nitrogen (N₂), the treatment width is slightly increased.
What is the recommended distance between the nozzle and the surface for the PlasmaBeam OEM system?
When installing the PlasmaBeam OEM, we recommend that you do not exceed a distance of 12 mm when using compressed air. The optimum speed is in the range of approximately 5–7 mm, but may vary depending on the distance.
What processing speeds are possible with the PlasmaBeam OEM?
The machining speeds for the PlasmaBeam OEM range from approx. 10–20 mm/s (for metals) up to several metres per second (for folding carton processing). Speeds of approximately 150–400 mm/s are often used.
Does the PlasmaBeam OEM produce any exhaust fumes?
Yes, in this PlasmaBeam OEM, the plasma is generated using compressed air or nitrogen in an electrical discharge. This primarily releases nitrogen oxides (NO and NO₂). A smaller quantity of carbon-containing exhaust gases is, of course, also possible (CO₂, CO). The system must be equipped with an effective exhaust air system!
Which materials can be activated using the PlasmaBeam OEM?
Virtually all solid materials, with the exception of thin polymer films and fluorinated polymers, can be electronically activated using Diener electronic’s PlasmaBeam OEM.
Which gases are typically used in the PlasmaBeam OEM?
Compressed air is the most cost-effective option. The PlasmaBeam OEM system from Diener electronic can be used with pure nitrogen or even with forming gas (N₂/H₂) up to a maximum H₂ concentration of XX per cent.
Can the PlasmaBeam OEM operate continuously, for example for 4–5 hours on the production line?
The PlasmaBeam OEM system from Diener electronic is designed for continuous operation and often runs non-stop for several hours during production.
Is it problematic to treat electronic components using the PlasmaBeam OEM?
The PlasmaBeam OEM from Diener electronic operates on the so-called ‘remote plasma’ principle, and the electrical discharge does not, as a rule, come into contact with the surface at all.
How can the cleaning quality of atmospheric plasma be described in relation to the PlasmaBeam OEM model?
The PlasmaBeam OEM from Diener electronic can remove very thin, trace-like organic contaminants. For heavier contamination (e.g. oil stains, drops, layers of paint), we recommend pre-cleaning using other methods.
Are exhaust air filters required for the PlasmaBeam OEM?
Yes, all systems must be connected to a proper exhaust system, regardless of the type of gas used. Nitrogen oxides, exhaust gases, fine oil mist (from oil pumps), etc. are produced, which must not be inhaled; furthermore, the gases are often acidic, meaning they accelerate the rusting of surrounding parts, machinery and equipment.
