Paint winding Rod

The paint mandrel test is a method for detecting the flexibility of coatings. It involves bending a coated sample panel around a cylindrical rod of a specified diameter and observing any cracking or peeling of the coating. The principle is to test the adhesion and ductility of the coating using bending stress, which is used to evaluate the crack resistance of the paint when the substrate deforms. This method is applicable to quality control in painting processes for furniture, metal products, and other items.
Selection
When selecting a coating mandrel, consider the type of test material and coating thickness, ensuring the mandrel diameter specifications match product standards. Verify the corrosion resistance of the mandrel material, inspect the surface smoothness and roundness accuracy of the mandrel. Confirm the stability of the bending operation mechanism, refer to industry testing standards to select the corresponding diameter series, and accommodate the deformation requirements of the actual substrate.
