Zipper reciprocating pull fatigue testing machine is a machine used to test the durability of zippers. It can simulate the frequent pulling of zippers in actual use to judge the durability and reliability of zippers. The machine usually uses an electric drive system to simulate the reciprocating pull of the zipper, and can record the number of reciprocating pulls of the zipper, and whether the zipper is broken, tightened, or the zipper line is broken during the test.
