velcro belt fatigue resistance tester
Velcro Fatigue Tester is designed for opening and closing the hook and loop fasteners, A hook and loop fastener is repeatedly opened and closed for a specified number, and then is rolled by a roller to the hook side and the loop side to stick closely so as to determine the adhesive force and strength. This machine has a memory function. You can adjust the force applied to the specimen by adjusting the counterweight and load.

FAQ
(1) What products can be tested with a Velcro fatigue resistance tester?
This tester is suitable for hook and loop fasteners used in footwear, textiles, clothing, bags, protective products, and industrial accessories. It helps evaluate whether fastening performance remains stable after repeated opening and closing cycles.
(2) What performance changes does this tester evaluate?
The equipment evaluates the effect of repeated fastening operations on adhesive performance, including changes in peel strength and shear strength. These results help manufacturers improve material selection and product durability.
(3) Which standards are supported by this test equipment?
The tester supports multiple standards including DIN 3415, SATRA TM123, ISO 22776, and GB/T 3903.20/3903.21, covering fatigue evaluation methods for touch and close fasteners in textile and footwear applications.
(4) Why is fatigue testing important for hook and loop fasteners?
During actual use, fasteners experience repeated opening and closing, which may reduce bonding performance over time. Fatigue testing helps predict service durability and identify potential quality issues before mass production.
(5) How can I select the correct testing solution for my fastener products?
Different fastener structures, materials, and application environments may require different test conditions. QINSUN engineers can provide technical guidance and customized solutions according to your products, standards, and laboratory requirements.
