Zipper Twist Testing Machine

Product Overview

The zipper torsion testing machine is a precision testing device specially designed for various types of zippers such as metal, plastic injection and nylon zippers, used to test the bonding strength and torsion resistance durability of zipper sliders and pulls. It is widely applied in zipper quality control and R&D verification in industries including garments, luggage and footwear.

Product Principle:

The equipment consists of a servo drive unit, a high-precision torque sensor, an angle encoder, a special fixture and a control system:

1.The fixture fixes the zipper slider and pull tab respectively to ensure firm clamping without slippage.

2.The servo motor drives the transmission mechanism to perform bidirectional torsion at the set angles (e.g. ±90°, ±150°) and speeds (0.5–2 r/min).

3.The sensor collects torque and angle data in real time, dynamically generates curves, and automatically records the peak torque, failure angle and cycle count.

4.The test stops automatically when the sample breaks, deforms or reaches the set parameters, and the data can be stored, printed or analyzed online.

Product Features:

1. Adopts touch screen control, featuring a simple and easy-to-understand interface, convenient operation, sensitive touch, and Chinese-English language switching.

2. The torsion-resistant fixture is made of stainless steel with a simple and elegant appearance.

3. The rotating structure adopts a low-noise reducer, ensuring stable operation and extremely low noise.

4. Three testing methods: torsion break test, fixed angle test, and fixed load test.

5. Can be connected to a computer and a printer.

6. All experimental data can be queried without connecting to a computer.

7. Microcomputer-controlled, with automatic testing, calculation and analysis of results, and data printing functions.

8. Units are switchable (cN·m and N·m).

High-quality metal, more sturdy and durable, compliant with testing standards, and featuring a longer service life.

Control panel
Precise and controllable force values, authentic and reliable data.
Programmable for flexible adaptation,
covering multi-scenario testing.
