When energy is continuously supplied to a matter, the temperature of the matter increases and it passes from solid state to liquid and finally to gaseous state. If the energy supply continues, the existing atomic shell disintegrates and charged particles are created (negatively charged electrons and positively charged ions). This mixture is referred to as plasma or the "fourth state of matter".
In short: Change of the aggregate state under energy supply: solid ⇒ liquid ⇒ gaseous ⇒ plasma
Natural plasma occurs for example in lightning, polar lights, flames, and the sun. Artificially created plasma is found in neon tubes, welding processes and in flash bulbs, among others.
Plasma is used in applications where it is important to combine materials or to specifically change their surface properties.
Nowadays, plasma technology is established in almost all sectors of industry, and new applications are being developed constantly.
This future-oriented technology allows for modification of a wide range of surfaces. Thus, many different applications are feasible, for example:
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.
More information
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.

FAQ Frequently Asked Questions
What are the benefits of plasma surface treatment?
Plasma surface treatment makes it possible to carry out essential processes without the use of wet chemical methods. Such a VOC-free process (Volatile Organic Compounds) offers the following major advantages:
- No need for chemical solvents
- no drying times between processes
- improved health and safety
- Enhanced environmental protection
- Uniform treatment, even in recesses and cavities
What processes can be carried out using plasma?
- Cleaning
- Activate
- Etching
- Coating
are the methods used to functionalise many surfaces with the aid of plasma pre-treatment.
What sets your atmospheric and low-pressure plasma surface treatment equipment, units and systems apart from those of your competitors?
