      The application field of nylon cable ties With the development of economy, the advanced application scope of socialized mass production is becoming wider and wider, involving almost all fields of application. As a result, the number of manufacturers of nylon cable ties has increased year by year, but the technology, quality, etc. are quite different, and the whole consumer goods market is full of mixed good and bad.
      As a nylon cable tie user, you also need to have basic selection reference knowledge in order to buy the most cost-effective nylon cable tie products that are most suitable for you and meet your needs.
1. Appearance quality (that is, visible to the naked eye)
      Usually plastic products will have defects such as edge defects, lack of material, burning, silver wire, bubbles, deformation, shrinkage, etc. that are easy to produce. These are also more likely to appear on nylon cable ties, so you have to pay attention to their appearance in detail. Although some of them do not affect the use, they will still cause potential threats to quality accidents.
      It is worth emphasizing that the key parts of the nylon tie are 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 avoid residual teeth. The top of the inner surface of the tooth cavity should not be There are step-shaped mold deviation marks, otherwise, there will be a large number of unusable sliding teeth, and the situation is difficult to insert, which is almost equivalent to waste and cannot be used.
      These problems need to be carefully paid attention to, just like the simple edge phenomenon. If the edge is too large, the tooth surface of the rear belt part and the tooth cavity of the head will not fit tightly, and the sliding teeth will easily loosen.
      The general rule is that for all products, except for special necessary requirements, the original product is the best, which is an axiom. A good nylon cable tie should be transparent and clear, even if the color is slightly yellow, it is not a big problem, and it should not be cloudy and black. The quality of the material is also a key point related to the quality. After the plastic undergoes multiple high-temperature melt screw shearing, its molecular structure state will change, especially for the raw material PA66 for making nylon cable ties, it is more obvious. The outstanding wear resistance and stretchability make this product rich in application in cable ties.
2. Performance quality
      The most important evaluation point of the nylon tie is its tripping force. If it is applied to a certain force, whether the belt is broken, or the tooth is reversed, the head is cracked, and the breaking method must be above the nominal tension. As for some users feel The poor quality of the cable ties is also partly related to the selected specifications. It cannot be paranoid that the quality of the cable ties is not good, because the standard value of the product of a specification has a bottom tensile force. When the force required in the use state exceeds the standard, it is very If it is too big, there is no guarantee. It can only be replaced by a product with a higher pulling force specification. Of course, the cost will increase, which is also a matter of choice. Of course, the tensile strength of good quality cable ties is flexibility and ductility is excellent, there will be no direct fracture section, and it will not become brittle. In this way, the applicable scope of the user's tensile force requirements can be met to a greater extent, thereby achieving the possibility of reducing costs.
