Longitudinal Fold Resistance Tester

The longitudinal folding endurance tester holds both ends of the sample and repeatedly folds it under fixed tension until it breaks, recording the number of folds. It is used to test the folding resistance of materials such as paper and film in the longitudinal direction, guiding adjustments in production processes and quality control.
Selection
When selecting, consider the required folding angle and tension range as per testing standards, ensure the sample size matches the fixture compatibility, the counting accuracy must meet the material characteristics, the structural stability of the equipment affects test repeatability, and the user interface should be simple for ease of daily testing operations.
