Testing Principle & Workflow
To replicate the stress zippers endure during daily use, the tester follows a standardized, repeatable process:
Secure the zipper sample and apply specified longitudinal and spherical tension (matching real-world pulling forces on zippers);
Drive the zipper slider at a constant speed, performing 30 reciprocating movements per minute;
Continue the test until the pre-set cycle count is reached, then assess defects (e.g., zipper jamming, puller detachment, or structural breakage) to determine the zipper’s fatigue resistance.
This workflow directly reflects a zipper’s long-term performance, helping identify potential failures before products reach end-users.
