Printing Film Coating Rod

The printing film applicator uses precisely calibrated grooves on the surface of a metal rod to quantitatively pick up the coating and scrape it onto the substrate, forming a uniform wet film. It is commonly used in laboratories and production lines for tasks such as ink opacity testing, pigment dispersion evaluation, and printability inspection, serving as a widely utilized coating tool.
Selection
When selecting, consider the substrate roughness to determine the diameter of the coating rod. Match the groove depth according to the coating thickness. Choose stainless steel or aluminum alloy material based on the viscosity of the coating. It is necessary to check the straightness of the rod body and the smoothness of the groove walls to ensure a uniform coating without discontinuities.
