Zipper fatigue testing: understanding the performance of zips over time

The zipper fatigue test is a test of the performance of a zip in long-term use by simulating the frequent stretching and shrinking of the zip during use. In practice, zips may break and the zip head may fall off after long periods of use and friction, affecting their service life and performance.

 

The zip fatigue test can be used to simulate actual use by subjecting the zip to long-term stretch and shrinkage tests to understand the performance of the zip over time, including strength, durability and wear resistance. Through the test, the service life and performance of the zip can be assessed to provide a reference for product design and production.
 

 

The zip fatigue test is usually carried out using a zip fatigue tester. The tester simulates actual use by controlling parameters such as the number of stretches and shrinks, speed and strength of the zip, and tests the zip over a long period of time. The tester can also record data such as the stretching and shrinking strength and deformation of the zip during the test, which can be used to analyse and evaluate the performance of the zip.

 

The zipper fatigue test can help companies assess the quality and performance of their products, improving their reliability and service life. It can also provide reference and guidance for product design and production by understanding the performance of zips over time.
