Zipper is a common accessory in our daily life, which is a connector completed by the joining, opening and closing of the attached teeth (teeth) on both sides. However, due to various reasons, zippers sometimes have problems, such as jamming, falling off, damage, etc., thus affecting the effectiveness of use. Therefore, it is necessary to learn to master zipper testing, and the following are the 10 steps:
Step 1: Prepare the zipper to be tested, and then observe whether both the teeth and the chain head of the zipper are intact and undamaged.
Step 2: Pull the zipper open. (If it cannot be opened, lightly spray some lubricant)
Step 3: Keep the zipper in an open state while checking whether the teeth of the zipper are well-proportioned and regular. If there are uneven teeth or missing teeth, the zipper can be judged to be of poor quality.
Step 4: Put the zipper together and check whether the chain head (zipper head) on both sides can be completely joined or whether there is any looseness.
Step 5: Pull the zipper to the central position, and observe whether the zipper can slide smoothly when it touches leather or other objects.
Step 6: Pull the zipper hard and observe if the zipper is damaged or deformed. If the zipper has hooks, buttons and other auxiliary parts, the same check should be done.
Step 7: Observe the sliding situation of the zipper step by step, if there is any jamming situation, it should be adjusted and handled in time.
Step 8: Open the zipper again and check whether the detail parts inside the zipper are as described in the illustration.
Step 9: After restoring the open state, check whether the interface part on both sides of the zipper is flawless. At the same time, you can measure the length of the zipper to see if it meets the standard.
Step 10: Finally, move the zipper several times by hand to check whether the zipper is unobstructed and noiseless, and if there is any noise, pay attention to whether it needs to be handled.
The above ten steps are the necessary skills to master zipper testing, and must be carefully tested in daily use to ensure the service life of the zipper.
