Common plastic products have defects such as flaws, lack of material, burnt, silver wire, bubbles, deformation, shrinkage and so on. These are also easier to appear on nylon cable ties, so you have to pay attention to check their appearance in detail. Although some do not affect the use, they will still induce the potential threat of quality accidents.
It is worth noting that the key part of the nylon cable tie is the quality of the toothed belt part and the tooth cavity of the head. This is very important, so the toothed belt part should be carefully observed to prevent residual teeth. The top of the inner surface of the tooth cavity should not There are stepped mold deviation marks, otherwise, there will be a large number of unusable sliding teeth, which will be difficult to insert, which is almost equivalent to waste and cannot be used.
These problems require careful attention. Just like the simple edge-cutting phenomenon, if the edge-cutting is too large, the tooth surface of the belt part and the tooth cavity of the head will not fit tightly after insertion, and it is easy to loose the slippery tooth.
The general rule is that for all products, except for special and necessary requirements, natural products are the best. This is an axiom. A good nylon cable tie should be clear and clear, even if the color is slightly yellow, it shouldn't be a big problem, not turbid and black. The quality of the materials used is also an important point related to quality. The molecular structure of plastics will change after repeated high-temperature melting and screw shearing, especially for PA66, the raw material for nylon cable ties, which is more obvious. The outstanding wear resistance and stretchability of the cable tie make this product rich in applications.
