1. Nylon 66 has poor low temperature resistance, and it is normal to break when the weather is cold in winter. If you want to solve this problem, you can add some materials which have better low temperature resistance and compatibility with nylon 66. Or replace the long chain nylon with better low temperature resistance. Cable Ties Manufacturer have materials to solve the problem of nylon 66 ribbons breaking in winter.

2. Do not think that the exquisite bag of particles is pure material, many are secondary granulation modified products, will inevitably undergo many high-temperature shear molding, the raw material itself molecular structure has undergone tremendous changes, performance has been reduced by half, coupled with degradation, oxidation, etc. The nylon band must ensure its flexibility, usually nylon has 3-8% of the period of water absorption, when the molecular structure is destroyed, how to cook, other means of water absorption are not helpful, which determines its brittleness, of course, easy to break;

3. The injection molding process of Cable Ties Manufacturer is also very important, in order to facilitate simple and good operation, by increasing the barrel temperature, accelerating injection time, and so on, will also make the bandage quality problems, details can be dissected bandage enlarged observation, some are filled with unsatisfactory holes, and so on. There are many kinds of nylon raw materials, choose the appropriate flexible system, such as Dan 6, etc. with the use of injection molding process must be strictly limited and optimized to avoid excessive processing damage to raw materials. In general, the improvement is focused on raw materials and injection process.

Summary
It depends on the specific circumstances. If it is a small size nylon tie, it is easy to break if the tension is too strong during use; if it does not reach the normal tension, it is easy to break; that is, the quality of the tie itself is a problem (some are made of recycled materials, new materials generally do not); and is used in low temperature and relatively dry places, ordinary China Cable Tie is easy to break (because the strap is brittle and the water loss is fast), so when you buy it, you have to explain the use environment to the Cable Ties Manufacturer and choose a more tough cable tie.

We judge the quality of China Cable Tie from its appearance. Generally speaking, we first pay attention to its edge defect, irregularity, a lot of burrs and so on, as well as to see if there is a burning condition when the color, or the color is very mixed, uneven color; die casting process, carefully look inside the Cable Tie. Whether there are small bubbles, or whether there is deformation, shrinkage and so on. And the most important is to observe the key part of nylon tie is the belt and the head cavity of the two parts, we observe the two parts of the belt should pay attention to the belt part can not appear leakage or uneven belt, there must be no mold deviation marks in the cavity, otherwise there will be sliding teeth or clamping teeth. The worse the quality, the worse the teeth can not wear, this kind of China Cable Tie is equivalent to waste tie is not normal use.
