Our special tungsten carbide coating was developed specifically for corrugated board production. The sophisticated coating process we use allows us to achieve top quality with high hardness, excellent wear resistance, outstandingly strong coating adhesion and low surface roughness. This tungsten carbide coating features constant caliper height throughout the operating time and across the working width. The homogeneously distributed carbide also offers extremely high density and hardness.
As an alternative to the tungsten carbide coating, we also offer Super Micro Chrome coating. Its special microstructure gives this 100 µm thick coating impressive runnability.
With our WLF tungsten lapping finishing process, we are able to achieve a perfect surface coating of < 0.2 µ Ra for optimal flute formation of all conventional medium papers.
