Nylon Cable Tie Application fieldsWith the development of economy, the application scope of socialized mass production is becoming increasingly broad, involving almost all fields. Therefore, the number of manufacturers of nylon cable ties has increased year by year, but the technology, quality, etc. are very different, and the whole consumer goods market is full of good and bad products.
As a nylon cable tie user, you also need to have basic selection reference knowledge so that you can buy the most suitable nylon cable tie products that meet your needs and are cost-effective.
1. Appearance quality (i.e., visible to the naked eye)
Common plastic products have defective products such as edge defects, missing materials, burning, silver wire, bubbles, deformation, shrinkage, etc. These are also more likely to appear on nylon cable tie products, so you have to pay attention to the detailed appearance. Although some of them do not affect the use, they will still induce the potential threat of quality accidents.
One point worth emphasizing is the quality of the key parts of nylon cable ties, namely the tooth belt part and the head tooth cavity. This is very critical, so the tooth belt part should be carefully observed, and no residual teeth should appear. There should be no step-shaped mold deviation marks on the top of the inner surface of the tooth cavity part, otherwise, a large number of unusable sliding teeth will appear, and the insertion will be difficult, which is almost equivalent to waste and cannot be used.
These problems all require careful attention, just like the simple edge phenomenon. If the edge is too large, the tooth surface of the belt part and the head tooth cavity will not fit tightly after insertion, and the sliding teeth are easy to loosen.
The general rule is that for all products, except for special requirements, the natural 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 yellowish, it is not a big deal, and it cannot be turbid and black. The quality of materials is also a key point related to quality. After multiple high-temperature melting screw shearing actions, the molecular structure of plastic will change, especially for the raw material PA66 of nylon cable ties. The outstanding wear resistance and tensile properties of nylon make it widely used in cable ties.
2. Performance quality
The most important evaluation point of nylon cable ties is its tripping force. When a certain force is applied, whether it is a broken belt, a reverse tooth, or a head crack, the breaking method must be above the nominal value of tension. As for some users who feel that the quality of cable ties is not good, it is also partly related to the selected specifications. It cannot be paranoid to think that the quality of cable ties is not good, because the standard value of the tension of a specification of product has a bottom. When the force required for the use state exceeds the standard, it cannot be guaranteed. The only choice is to replace the product with a higher tension specification. Of course, the cost will increase, and there is no way to do it. Of course, the stretch of a good quality cable tie is flexible and ductile, and there will be no direct fracture section and it will not be brittle. This can also meet the user's tensile force requirements to a greater extent, thereby achieving the possibility of reducing costs.
