Coater blades for board and paper making

Carbide coater blades for optimized process performance

In blade coating paper quality variations and rapid wearing of coater blades inevitably result in production losses and higher blade costs which can be easily avoided by using Valmet’s high quality carbide coater blades. Valmet Coater Blade* family consist of four carbide blades which leave a uniform layer of coating color on paper/board surface, thus creating an excellent finish for desired coat weight. In addition to having a major impact on end product quality, Valmet blades also improve production efficiency which in turn leads to more saleable production.

Improved performance with Valmet Coater Blades

Valmet Coater Blades are high quality carbide blades with extremely low wearing rate. 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.

Read the performance of Valmet Coater Blades below in terms of paper quality and length of lifetime - with 5/5 being the highest performance and 1/5 the lowest.
