Coating Adhesion Cupping Tester

The paint film cupping tester uses a steel ball or punch to uniformly press against the back of the sample, causing the paint film to gradually bulge and crack along with the substrate. The depth of indentation is measured, which reflects the crack resistance, adhesion, and other properties of the paint film during deformation. This method is used for quality control in industries such as coatings and coiled materials.
Selection
When selecting a cup drawing test machine for paint films, it is essential to consider compliance with testing standards such as ISO 1520 or GB 9753. The measurement range should cover 0.1–20 mm, and the indenter diameter must align with the standard specifications. The machine should feature digital depth measurement and constant-speed advancement functions. Additionally, sufficient rigidity of the body is required to minimize vibration, and comprehensive calibration certificates should be provided.
