To meet the requirements for a functional coating that is highly resistant to abrasion and corrosion and suitable for high-resolution laser engraving up to 700 L/cm, Zecher relies on plasma coating technology. Plasma coating enables the required functional layers to be realized with qualitatively convincing mechanical properties as well as residual porosities of less than 1%.
The applied functional layer forms the basis for engraving the anilox rollers and sleeves. The established and high-quality chromium oxide ceramics (Cr2O3) are characterized by good melting behavior and high density. The nature of the ceramic coating determines the precision, the printing properties, and the long-term performance of the ceramic rollers.
