Flexible coating Rod

The flexible coating rod is a metal rod with helical grooves that quantitatively transfers coatings through these grooves. During coating application, the rod rolls, and the grooves carry out a fixed thickness of liquid to form a uniform wet film. It is used for ink hiding power tests, paper coating experiments, and printability evaluations.
Selection
When selecting, consider the wire diameter to determine the coating thickness; thicker wire diameters require thicker coatings. Materials include stainless steel and chrome plating, each offering different corrosion resistance. The groove shape affects fluid characteristics, with V-shaped grooves being suitable for low-viscosity liquids. The straightness of the rod body influences coating uniformity, so it is necessary to check for any bending or deformation.
