Surface treatment by professionals
With plasma and parylene systems from Diener electronic
Diener Surface Treatment
For more than 30 years, Diener electronic has been designing and manufacturing systems for the treatment and optimisation of surfaces. With in-house process development, Diener develops processes for plasma, parylene and vacuum treatments. As a service provider, surface treatment is also carried out at the Ebhausen headquarters.
The benefits of plasma solutions
Plasma cleaning
Plasma micro-cleaning gently removes molecular and organic contaminants from almost all surfaces without damaging the components.
More information
Plasma activation
Plasma activation increases the surface energy, ensuring optimum wettability during painting, gluing, printing or bonding.
More information
Plasma etching
Plasma etching of a surface creates a textured surface to ensure strong adhesion. Isotropic etching is achieved through chemical etching, whilst anisotropic etching is achieved through physical etching.

Plasma coating
Plasma can be used to treat workpieces with various coatings. To do this, gaseous and liquid raw materials are fed into the vacuum chamber.
More informationPlasma is a high-energy ionised gas produced by a continuous supply of energy. When it comes into contact with a surface, it gently removes the finest impurities without damaging the component and increases the surface energy. Liquids spread more easily, adhesion is improved, and adhesives or paints bond reliably. Plasma surface treatments can be used to prepare the surfaces of any material specifically for subsequent processing steps. Non-polar plastic surfaces that are difficult to bond, for example, are optimised through plasma activation, ensuring reliable bonding properties.

Customised plasma systems for your production
Diener electronic offers a wide range of low-pressure and atmospheric-pressure systems, complemented by bespoke special-purpose systems for various industries. Whether you require a plasma system as a stand-alone solution or fully integrated into your production line, Diener electronic’s plasma systems are individually tailored to your specific requirements. Diener also offers plasma systems with an optional automatic door to meet the growing demands of Industry 4.0. The plasma system can thus be quickly integrated into an MES and optimally incorporated into automated production lines. The option of automated loading and unloading reduces the need for manual intervention, which increases process reliability and enables reproducible processes. Thanks to this automation, the modern plasma systems ensure efficient quality control.
Proven process technology
With over 30 years’ experience, Diener electronic possesses expertise in plasma and parylene processes that keeps pace with the growing demands of the industry. Our process development department is always on hand to help you identify the right equipment and explore the process window for your requirements. From simple cleaning processes to complex coatings, we develop all processes in-house. To this end, our technical centre is equipped with 30 systems featuring various configurations for testing. During our joint trials, we are happy to adapt not only the process parameters but also the plant components to suit your specific requirements. As we carry out plant construction in-house (“Made in Germany”), we can undertake modifications to electrodes, workpiece carriers or special assemblies ourselves within a short timeframe.
