FAQ (Frequently Asked Questions)

Q1: What specific zipper defects can the GT-C39A identify during laboratory testing?

A: This machine performs continuous reciprocating tests to simulate real-world wear. It accurately detects defects such as joint gap expansion, chain loosening, connector failures, fabric fluffing, and slider wear.

Q2: Does the machine stop automatically when the target testing cycle is reached?

A: Yes. The GT-C39A Zipper Tester features an integrated LCD automatic counter (0-999,999 cycles). The machine stops automatically once your preset count is reached, allowing for safe, unattended lab operations.

Q3: Can the lateral and longitudinal tension be adjusted for different zipper sizes?

A: Absolutely. It is equipped with highly precise vertical and horizontal spring balances and manual adjustment knobs. Lab technicians can easily calibrate and adjust the exact tension needed to match specific global standards.
