The zipper torsion tester is used to test the binding strength of the zipper pull head and whether it can withstand the specified torque value, so as to provide various improvement references and quality control basis for production.

Application

Zipper torsion testers are widely used in various fields, including but not limited to:

Apparel industry: Ensuring the resistance of zippers in outerwear, trousers, and skirts to wear and tear during use.

Luggage and bags: Ensuring the stability and durability of outdoor sportswear and travel bags under frequent opening and closing.

Footwear products: Ensuring the torsional resistance of shoelaces during use.

These testers simulate various conditions that zippers might encounter in real-world use by applying specific torque and tension, thereby ensuring product quality and user satisfaction.

Test Procedures

The operation method of the zipper torsion tester includes the following steps:

Pre-use check: Ensure the limit switch is properly positioned and secure to avoid damaging the sensor or clamp.

Sample loading: Fix the zipper pull and tab to the clamp respectively, and twist at a speed of 1.5 r/min.

Testing: Directly read the torque data. During testing, fix the zipper pull and tab to the clamp respectively.

Data processing: Data processing includes marking the original gauge length, saving and retrieving test data.

Report printing: Preview the test results before printing using the connected printer.

Maintenance Information

Maintain zipper torsion testers by cleaning debris with a lint-free cloth after each use, lubricating moving parts (especially bearings) regularly to ensure smooth reciprocating movement. Inspect clamps for wear from high-force testing, check for loose screws, and store in a dry environment to prevent rust.
