The service life of nylon zippers

When using nylon zippers, it is important to pay attention to four methods. When pulling the zipper, do not be too hasty. When using it, do not overfill the items. Zipper alignment mainly refers to straightening and aligning the chains at both ends before closing. Especially for long zippers on clothes, it is necessary to align the two ends of the teeth before pulling them, otherwise it will be very easy for the zipper to detach from the end and cause misalignment and damage to the teeth. Nylon zippers should not be pulled too quickly during the pulling process. It is required to hold the zipper head with your hand during the pulling and closing process, and then quietly pull it forward along its trajectory. The force should not be too strong or too fast. If you encounter obstacles during the pulling and closing process, you must not forcefully pull the nylon zipper back. If you forcefully pull it, it is easy to damage Mia. When you cannot pull the slider, you can apply a layer of white wax on the tooth surface. This not only makes it easy to pull, but also makes Mia durable. After pulling and closing, the lateral tension of the nylon zipper product is limited by a certain limit. If it is loaded too much, it is easy to damage Mia. Full, exceeding the lateral pulling force allowed by its zipper, this will directly cause its belly to break and the zipper locking mouth to open and become larger, Causing the teeth to bite less tightly.
In fact, there are three situations where the strength of this nylon zipper does not meet the requirements. If we can analyze and handle these three situations well, trust can eliminate this overall problem. Mingguang Zipper specializes in producing zippers. Friends in need can contact us. After testing, we found that both the adhesive and the insertion tube were good, but the socket was damaged and we couldn’t remove all the adhesive. Actually, this is because the wall of the socket’s conduit is too thin, or perhaps due to the insufficient strength of the formaldehyde material. At this point, we need to make corrections to the transparent zipper of the injection mold and replace the formaldehyde material. The second type is cloth glue, it’s not broken, but the cloth glue in the insertion tube and socket hasn’t completely come out. Perhaps it’s because the ribs are too thin, or some of the ribs with adhesive have been cut off. Perhaps it’s due to the lack of reinforcement or the holes being too small. We can adjust the thickness of the punching knife by increasing the ribbed roughness of the compression mold, and also add nails for punching holes. The third type is that both the insertion tube and socket are good, but the adhesive is broken. Perhaps it was due to the high temperature of the ultrasonic glue sticking machine, which burned out the chain and fabric glue, or the holes were too large. We can adjust the ultrasonic frequency and pressure of the glue sticking machine, or replace it with a standardized hole.
