Molding Rod

The coating rod is a metal bar used in the coating process to control the thickness of the coating. It regulates the amount of coating material through the gap between the rod and the substrate. The smoothness of its surface determines the uniformity of the coating, and it is used for predetermined quantitative coating of materials such as paper and film.
Selection
When selecting an applicator rod, it is essential to match the substrate width and the Coater model. The rod diameter should be chosen based on the viscosity of the coating material, while the hardness of the rod body should be determined according to the required coating thickness. Additionally, the surface treatment process should be selected based on corrosion resistance requirements in the production environment.
