With the development of economy, the application fields of nylon cable ties are more and more extensive, involving almost all industries. When we use nylon cable ties, we recognize that the quality of the cable ties is the necessary knowledge, and buy the one that best suits our needs and is the most cost-effective. We can distinguish the quality of nylon cable ties from two aspects. 1. Appearance quality (i.e. recognizable by the human eye) Common plastic products will have defective products such as defects, lack of materials, scorching, silver wires, air bubbles, deformation, shrinkage, etc. These are also easier to present in nylon cable ties, so we have to pay attention to the detailed look. Although some products do not affect use, they still pose a potential threat to quality accidents. It is worth noting that the key parts of the nylon tie are the quality of the toothed belt part and the head tooth cavity, which is very critical. Therefore, the tooth belt part should be carefully observed, and there should be no residual teeth. There should be no trapezoidal die offset marks on the top of the cavity. Otherwise, there will be a large number of unusable sliding teeth, almost equivalent to waste, unusable. These problems must be carefully paid attention to, such as simple edge conditions, the edge is too large, the tooth surface of the crossed belt is not close to the tooth cavity of the head, and the sliding teeth are easy to loosen. The general rule is that for each product, without the unique and necessary provisions, the primary color 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 no big deal, and it cannot be cloudy black. The quality of the material is also key to quality. After many times of cutting effect of high temperature melting screw, the molecular condition of plastic will change, especially PA66, the raw material for making nylon tape. More obviously, nylon’s outstanding wear resistance and tensile properties have promoted the wide range of cable ties products. application. 2. Feature quality The most important evaluation point of nylon cable ties is its tripping force, which is applied to a certain force. Whether it is broken belt, reverse tooth or head split, how to break must be above the nominal pull force. For some customers, they think the cable ties are of poor quality, some are related to the selected specification. They can’t be paranoid that the quality of the cable ties is not good, because the standard value of a product of a specification has a bottom. When the stress required for the service state is greater than the specification, there is no guarantee. Naturally, a good quality cable tie is flexible in stretch, has excellent ductility, will not have a direct rupture cross section, and will not become brittle. In this way, the application range of the user’s application tensile force requirements can be met in more aspects, thereby achieving the possibility of reducing costs.
