Coater blades play an important role in the paper or board making process. They hugely affect efficiency, both materials and time, and have a major impact on final product quality. In blade coating, paper quality variations and rapid wearing of coater blades inevitably result in production losses and higher blade costs. The Valmet Coater Blade family consists of four carbide blades which leave a uniform layer of coating color on paper or board surface, thus creating an excellent finish for desired coat weight. In addition to having a major impact on end-product quality, blades also improve production efficiency which in turn leads to more saleable production.
The Valmet coater blade selection consists of high-quality carbide blades with extremely low wearing rates. The selection covers blades optimized for different coating positions, available for bent and stiff blade applications in all geometries. This product portfolio offers coater blades for improved process performance and makes it easier to choose just the right blade for your needs.
Through extensive research and development, we have developed the new generation of coater blades - Valmet Coater Blade nC2. This nano-carbide blade with unique properties such as wear resistance, carbide hardness, streaking tendency and a short run-in time, stabilizes the blade coating process, which results in excellent paper quality in the most demanding coating processes.
nC2 especially suits positions that require high quality printing surfaces. It is available in bent and stiff blade mode, in all geometrics and for any original equipment manufacturer applications.
