Steinhagen, November 2025 – At Euroguss 2026 in Nuremberg/Germany, Plasmatreat GmbH will demonstrate how atmospheric pressure plasma makes metal surfaces reliable for subsequent steps such as coating, sealing, bonding, and printing.
From January 13 to 15, 2026, visitors to Hall 6, Booth 219 can experience live how plasma is revolutionizing surface treatment – with a focus on highly effective cleaning, innovative nano-coating as corrosion protection, and maximum inline process capability.
Plasmatreat's innovative plasma processes, such as Openair-Plasma, HydroPlasma, and PlasmaPlus, not only ensure effective surface modification and maximum efficiency, but also make processes more efficient and environmentally friendly.
Removing inorganic residues with HydroPlasma
With HydroPlasma, Plasmatreat has developed a new cleaning process that combines the physical effect of Openair-Plasma with the chemical reactivity of water. Water is fed into the plasma process and ionized. The resulting reactive species dissolve organic and inorganic residues and convert them into soluble or gaseous components. The effect is similar to intensive cleaning with detergent in warm water, but without the need for additional chemical cleaning agents. The focus of the trade fair presentation is therefore on the PTU cell (Plasma Treatment Unit) type 1212. This demonstrates how workpieces are cleaned of contaminants using HydroPlasma.
Live demonstrations at booth 219 in hall 6
Various aluminum and magnesium sample parts will be treated at a live table. Visitors will be able to see directly how the ultra-fine cleaning of metal surfaces improves wetting and adhesion. In addition to the illustrative fine cleaning of metal components, visitors will also have the opportunity to see analysis methods for verifying plasma treatment. The company has developed an innovative and rapid test procedure – the AntiCorr test fluids – specifically for the fast verification of AntiCorr coating.
Within seconds, visible and evaluable results are achieved that allow reliable conclusions to be drawn about the success of the coating. This state-of-the-art approach is transforming the evaluation process and offering unprecedented efficiency.
Ultra-fine cleaning with Openair-Plasma – precise and chemical-free
The surfaces of metal components are often contaminated by the release agents, lubricants, cutting oils, or drawing greases required in the manufacturing processes. These contaminants must be removed to ensure flawless further processing. Conventional cleaning processes usually involve chemicals. Nevertheless, residues often remain, which make further processing of the components, e.g., bonding, sealing, or coating, difficult. Plasmatreat's Openair-Plasma technology is a thorough and environmentally friendly alternative to wet chemical cleaning. This technology requires only compressed air and electricity to remove organic contamination. It is therefore a very clean technology that is efficient, suitable for inline use, and can be applied selectively.
PlasmaPlus AntiCorr coating – preventing corrosive infiltration
PlasmaPlus, another process developed by Plasmatreat, applies a nano-coating to metal substrates. A precursor is added to the plasma to create an ultra-thin, highly effective layer on the metal surface, which performs a specific function depending on its composition: The PlasmaPlus AntiCorr process is used for high-performance corrosion protection coatings, which serve, among other things, as a protective layer under housing seals. This protects components from infiltration corrosion, effectively preventing damage to electronic components, for example. The key advantage of AntiCorr is its selective inline treatment, which means that only the desired and necessary areas of the component are treated. Compared to other corrosion protection processes, this saves a lot of chemicals, logistics costs, time, and money, while also protecting the environment.
