Paint Film Bend Resistance Tester

The paint film bending tester evaluates the cracking or peeling of coatings by bending coated panels around an axis. It is used to assess the adhesion and flexibility of coatings on deformed substrates, commonly applied in quality control for industrial coatings such as metal cans and coils.
Selection
When selecting, consider the required bending diameter and speed range according to the testing standards, and confirm that the sample thickness is compatible with the fixture. Match the testing conditions corresponding to the material type, check whether the mandrel specifications cover common bending angles, and ensure the equipment structure can stably perform the reciprocating bending action.
