Zipper Tester - TNG1100

The TNG1100 is designed to assess the fatigue resistance of zippers by subjecting them to repeated reciprocating motion while applying lateral and longitudinal forces. The test specimen is secured to the machine, which moves the zipper head at a constant speed of 30 cycles per minute. The instrument supports EN 16732-5.7 and QB/T 2171 standards. It is suitable for testing various zipper types, including metallic, coil, nylon, and plastic zippers. The machine features an adjustable counter that can be set from 1 to 999,999 cycles. A built-in sensor detects when the zipper is about to break and stops the test automatically. The device has a working area of 560 mm in length, 350 mm in width, and 700 mm in height. The adjustable stroke range is 40 to 100 mm, allowing customization based on test requirements. The TNG1100 provides a reliable method for evaluating zipper performance under simulated real-world conditions.

Zipper Reciprocation Fatigue Tester, is designed to determine the resistance to reciprocation of the zipper (slide fastener), such as a metallic zipper, coil zipper, nylon zipper, and plastic zipper. When carrying out the zipper test, the test specimen is subject to a specified number of cyclic operations whilst under lateral and longitudinal tension.

The Zipper Tester catches the head of the zipper to do the reciprocating movement at a constant speed for 30 times per minute. The tester automatically stops the test when the counter reaches a specified number of times. Equipped with a sensor, the machine will stop automatically before the zipper is broken. Moreover, it provides adjustable stoke of 40~100mm as requested. Besides, the zipper reciprocation tester consists of a set of clamps with a reciprocating motion transmission system and display system.

Smooth precision engineering parts with excellent performance.

Chinese and English interface as well as the menu-based operation mode.

Equipped with a sensor, automatically stops before the zipper is pulled.

Special zipper head clamps with a built-in opening structure for easy use.

Adjustable zip stroke for different criteria, adjustable horizontal and vertical tension.

Test principle

In the test, the machine drives the zipper slider at a constant speed and moves up and down 30 times per minute. The machine will stop automatically if it runs at specified times. Finally, we can check the condition of the test sample and determine the performance of the product.

1 Prepare test apparatus and zip specimens (250mm or more) according to standard requirements at first.

2 Rub the front and back side of the zip specimen with paraffin wax several times respectively.

3 Check the tester so that the pull tab jig remains in the lower position and fix the zip.

4 Apply different loads to different zips according to the standard.

5 Start the tester and complete the specified number of passes or until the specimen breaks, then record the test results.

Strictly meet standards

All data for meet the standard parameters.

Consistency with international third-party laboratories

The test data are comparable to the test results obtained by well-known international third-party laboratories.

High repeatability

With the same set of samples and the same machine, after multiple tests, the results will remain consistent.

What is A Zipper Reciprocation Tester The zipper reciprocation tester is used to test whether the zipper can withstand reciprocating pulling operation according to a specified number of times when the zipper is reciprocating under transverse and longitudinal tension in the instrument. During the test, the tester drives the zipper at a constant speed and moves it 30 times per minute until the specified number of times is completed. Slider fastener reciprocating tester mainly detects the limit value of zipper endurance and makes a reasonable evaluation of zipper performance. Test Project 1. Test of flat tensile strength: flat tensile strength is the most basic strength index used to test the ability of the teeth chain to resist transverse force in an occlusal state, which is very similar to the state of actual use.
