Common plastic products have problems such as flaws, lack of material, burnt, silver wire, bubbles, deformation, shrinkage, etc., which are easy to produce defective products. These are also more likely to appear on nylon cable ties, so pay attention to carefully check its appearance. Although some problems do not affect the use, there are still potential threats to induce quality accidents.
The most important evaluation focus of nylon zip ties is its release force. A certain force is applied to it, whether it is fracture, anti-tooth, or head cracking, these fracture methods must be above the nominal tensile value.
Some users feel that the quality of the cable tie is not good, partly because of the selected specifications. It should not only be considered that the quality of the cable tie is not good, because the standard value of the product of a specification has a limit. When the tensile force in the use state greatly exceeds the standard value of tensile force, there is no guarantee, and you can only choose a substitute product with a higher tensile force specification. Of course, the flexibility and ductility of good-quality nylon cable ties when stretched are excellent. In this way, the scope of application of the user's pulling force requirements can be met to a greater extent, so as to achieve the possibility of reducing costs. And there are many types of cable ties, like double loop cable tie, waterproof cable tie and so on.
It is worth noting that the quality of the key parts of the nylon cable tie is the toothed belt part and the tooth cavity of the head. This is very important, so the toothed belt part should be carefully observed, and there should be no residual tooth phenomenon. There should be no stepped mold deviation marks on the top of the inner surface of the tooth cavity.
