Where did the stain on the PP Zipper Braided Sleeve come from?

"Stain" is a product with poor appearance for PP zipper sleeves, and it will also affect the use of PP zipper sleeves. If the stain is slight, customers who are easy to talk may not care about it, and customers who are not good at speaking may ask For returned goods, if the stain is serious, it can only be treated as a defective product. So where did the stains on these PP Zipper Braided Sleeve come from?

First of all, check the raw materials of the Cable Sleeve. If the environment of the PP zipper Braided Sleeve production workshop, molding workshop, and material preparation workshop is not clean, the raw materials of the Cable Sleeve are not well preserved and exposed to the air, it is easy to absorb dust, which will cause PP zipper weaving. The sleeve molding is stained.
Secondly, if there is a lot of dirt in the production mold or production equipment and surrounding areas, then the product will cause a lot of dirt in the mold cavity during the production process, and then the molding will cause stains.
In addition, the external release agent itself is dirty, and when the release agent is sprayed, the dirt is also sprayed out and adsorbed on the surface of the cavity, resulting in dirty button surfaces after molding.
Finally, it may be that the electric heating plate under the vulcanizing machine is dirty. As long as the mold is closed, the dirt will be sucked into the mold cavity, resulting in stains on the PP zipper sleeve.
The slightly deformed PP Zipper Braided Sleeve can be used normally after recovering its shape, and the sealing function will not be lost, while the severely deformed PP Zipper Braided Sleeve will lose its sealing function even after recovering its shape, and cannot be used normally. If the PP Zipper Braided Sleeve is stored for a long time, it will be slightly deformed. So how to restore the deformation of the PP Zipper Braided Sleeve?
First, take out the deformed PP Zipper Braided Sleeve, boil a pot of water, and pour it into a container. After pouring boiling water into the container, soak the PP Zipper Braided Sleeve in boiling water. After soaking for a few minutes, take out the PP Zipper Braided Sleeve and pull it by hand. After pulling it, it will be fine after the elasticity is restored, so that the PP Zipper Braided Sleeve will return to its original shape.
In short, the choice of Cable Sleeve must be done well. Its friction coefficient must be low, lubrication must be in place, and its contact surface must be smooth, not rough or stained. During the installation process, it is necessary to ensure the coaxiality of the installation, and the eccentricity must not be too large. At the same time, the rationality of the sealing system must be ensured, and there must be no excessive dimensional error, which will cause deformation of the PP zipper braided sleeve.
These are just the 4 points that Xiaobian summed up to cause stains on PP Zipper Braided Sleeve. There may be other uncommon situations. I won`t say more here. Stains on PP Zipper Braided Sleeve will increase the production of enterprises. Cost, reduce customers' trust in the enterprise and reputation in the industry, we hope we will work together to weave a blue sky for the network management industry.
