Nylon cable ties application field With the development of economy, the advanced application range of socialized mass production is becoming wider and wider, covering 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 very different, and the whole consumer goods market is filled with uneven quality.
As a nylon cable tie user, you also need to have basic selection reference knowledge, so that you can buy the most cost-effective nylon cable tie products that are most suitable for your needs and meet your needs.
1. Appearance quality (that can be recognized by the naked eye)
Normal 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 of them do not affect the use, they can 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. Therefore, the toothed belt part must 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 a 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 being inserted, and it is easy to loosen 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 translucent and clear, even if the color is slightly yellow, it shouldn't be a big problem, and it should not be turbid and black. The quality of the materials used is also an important point related to quality. After many times of high-temperature melting and screw shearing, the molecular structure of plastics will change, especially for PA66, the raw material for nylon cable ties, which is more obvious. The outstanding abrasion resistance and stretchability of the cable make the product can be widely used in cable ties.
2. Performance quality
The most important evaluation focus of nylon cable ties is its release force. When applied to a certain strength, whether it is broken, or reversed teeth, or the head is cracked, no matter how the breaking method must be above the nominal value of tension, some users feel that The poor quality of the cable tie is also partly related to the selected specification. It should not be regarded as the bad quality of the cable tie, because the standard value of the product of a specification has a bottom. When the force required in the use state exceeds the standard, it is very If it is too large, there is no guarantee. You can only choose to replace products with higher tensile strength. Of course, the cost will rise. This is also no way. Of course, good quality cable ties are flexible and extensible when stretched. They will not have a straight fractured section and will not be brittle. In this way, it can also meet the scope of application of the user's pulling force requirements to a greater extent, so as to achieve the possibility of reducing costs
