Zipper Reciprocation Fatigue Tester

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.
