T-bend testing machine

The T-bend tester evaluates the adhesion and flexibility of coatings or films under bending stress by subjecting the specimen to 180-degree reciprocating bending around a fixed axis. It is used to assess the crack and peeling resistance of materials such as paints, inks, and plastics during processing or use. This instrument is commonly applied in quality control within industries such as coil coatings, printing, and packaging.
Selection
When selecting, it is necessary to match the material thickness range with the bending axis diameter specifications and confirm that the testing standards comply with industry norms. Consider the maximum bending angle and speed adjustability, paying attention to the anti-slip design of the fixture and the sample protection function. The structural rigidity of the equipment affects data stability, and the operation interface should be intuitive to simplify manual steps.
