Project Description
AT-T4006 Button Snap Pull Tester China Manufacturer
Button Pull Test Machine is also referred to as the button snap pull tester. It is mainly used as a textile testing machine or a toy testing machine intended to determine the breaking or pull strength of buttons, snaps, fasteners, ornaments, etc,. attached to garments, fabrics, toys, shoes, etc.
This snap button pull test machine is an effective tool to help manufacturers to check whether various attachments of the final products are firmly fastened and reach the specified requirements. If the buttons on the baby clothes are easy to fall off, which is not only a quality problem but also a hazard of being swallowed by the baby in contact. Therefore, all buttons and decorative parts on garments must be tested with a button snap pull tester in the product development stage and during the spot check on finished products to check whether their firmness meets relevant safety standards.
There are 2 measuring methods: One is that the operator operates the instrument to continuously apply a pulling force to the targeted button, attachment or ornament until it is separated from the base sheet of the specimen. The force required at the time when the stripping occurs is recorded as the test result.
The other is that a constant pulling force is applied to the button or ornament for a specified period of time. The operator inspects whether the attachment and the base sheet are separated or the damage to the specimen occurs. The state of the measured sample is recorded as the test result.
We can supply different styles of pull testers. In addition to analog machines, we can also supply digital display models and electromechanical models. For more styles and grips, please contact us directly.

A piece of fabric with a button or other ornament is placed on a circular rubber pad and clamped by a ring-shaped fixture, enabling the targeted attachment to be up and in the middle of the ring. A matched upper gripper connected to the force gauge is adjusted downward by turning the handwheel to grip the attachment.
An upward force is applied by turning the handwheel to pull the attachment for a given period of time or until the failure of the specimen occurs. The holding or breaking strength is measured.

The button pull test procedure is not complicated. As long as you have this instrument, you can quickly master the button pull test method.
1) Take out the stand and all the accessories from the package, first install the two control levers on the lower fixture assembly and the upper module located on the supporting rod by screwing. Then install the force gauge to the corresponding module.
2) Connect a hook to the lower part of the force gauge, and then turn the handwheel to lower the hook until making contact with the lower clamping fixture to correct the center point of the fixture. If the hook is not centered in the lower fixture, you can move and adjust the position of the whole lower fixture assembly to align with the center by losing and fastening the 4 butterfly nuts at the bottom. After the position correction is completed, revert the gauge to a suitable height.
3) Hang the weight (15lb) on the hook to complete the button pull test machine calibration.
4) Choose an upper grip that matches the test sample and hang it on the hook to complete the installation of the upper grip.
5) Place a fabric sample with a button on the rubber pad of the lower clamping device, with the button facing upwards, and use the ring fixture and lever to firmly fix the sample to prevent the slippage, ensuring that the fabric is flat and the button to be tested is in the middle of the fixture. The fabric is not affected after the button is held. (Note: If the test sample is the grasp button or buttons with a large size, the lower fixing fixture needs to be replaced with the grasp button accessory kit, and the upper fixture needs to use the grab button grip accordingly).
6) Turn the handwheel to descend the upper grip to an appropriate height and adjust the clamping mouth to hold the button firmly, enabling the upper grip, and the button to be in a vertically relaxed state.
7) Adjust the force gauge to “Zero” position manually, or enable the switch of gauge to be at a “on” position.
8) Press down the control lever to pull the upper grip upward, applying a pulling force to the button until it disengages from the fabric or the fabric tears. Or apply specified tensile force and hold for a given time. Generally, each button must be able to withstand a minimum of 17 lb (7.72 kg) of pulling force and need to be maintained for 10 seconds without any trace of looseness or damage.
9) At least 20 buttons must be tested for each button style, and all of them have to be considered qualified. If one of them is loose or damaged, all need to be replaced and tested again.
What Grips and Accessories Can I Get with the Snap Button Pull Test Machine Together?
We will provide a set of standard accessories with the machine to meet the testing requirements of most customers. If your test sample is very special and requires unconventional grips to complete the test, you can buy it separately from us.
The standard accessories are as follows:




1. A force gauge
This force measuring device is the core component of this button snap pull tester, because it is responsible for measuring and displaying the pulling force of the sample during the test. It is an analog gauge with a pointer and scale or Push-pull meter (Force gauge) with an LCD screen, featuring high accuracy, easy operation and intuitive reading. Its maximum scale is 300N. (If you want to choose a high-end force gauge, IMAD is an alternative).
2. A Calibration Weight(15 lb)
It is used to calibrate the accuracy of the force gauge (15 lb = 6.82 kg)
3. Lower Fabric Clamping Device & Level Arm Locking
A sheet of fabric test piece with a button is flat placed on the rubber pad and clamped by the locking mechanism to prevent slippage during the test.
4. Lower Grasp Button Accessory Kit
This set of kit is mounted to test on grasp buttons or large buttons up to 30 ligne. It is mainly used together with the upper grasp button grip.

5. A long Nose Vise Grip
It looks like a long nose and features a vise with 2 jaws to clamp hooks for trousers, retaining rings and other small accessories on garments.
6. A Three-Pronged Grip
It features 3 prongs on the gadget. The clamping mouth is adjustable to accommodate attachments of different sizes.
7. An Upper Grasp Button Grip
It is designed to grip the grasp buttons or larger buttons, like Jeans or plastic buttons up to 30 ligne. A special lower clamping kit is provided by us to match this grip.
8. An Upper Universal Female Grip
It is intended to test on the female part and stud part of the snap, which is one of the most commonly used grips.
9. An Upper Stud Clamp
It is used to test on the male part of the snap, but generally, upper universal female grip can be also used instead.
The optional accessories are as follows:
1. Small Part Cylinder
This cylinder is used to confirm whether the accessories are classified as small parts or not in conformity with EN71 & ASTM F963.
2. Multi-Function Vise Clamp
It is used to fasten the fabric between the jaws and can be used with other upper grips for testing on the attachments like Patches, side tabs, zippers, pullers, etc.
