Analysis of the toughness and fracture causes of nylon cable ties:

1. A brief and detailed introduction to nylon cable ties. Due to the diversity of products (thick walls, large injection molding steps), nylon cable ties pay great attention to their grinding tools, injection molding processes, and materials. Generally, new manufacturers must explore the entire process for a long time in order to produce products that meet the standards. The design scheme has a locking function (except for the buckle type), which only tightens as it is tied, and it is also a detachable cable tie (buckle). Nylon zip ties are made of UL approved Nylon 66 material through injection molding, with a flame retardant rating of 94V-2. They have excellent corrosion resistance, erosion resistance, dielectric strength, are not easily brittle, and have strong load-bearing capacity. The working temperature ranges from -20 ℃ to+80 ℃ (usually nylon 66). The market is used for fixing internal electrode connection wires in hardware factories, binding televisions, computers, and other products, as well as for fixing internal routes in lighting fixtures, electric motors, electric toys, and other products. It is also used for fixing fuel pipelines in industrial equipment and cable routes on ships, The whole bicycle can be packaged or tied to other objects, and can also be used for tying objects in agriculture, animal husbandry, horticulture, flowers, handicrafts, and other fields. This product has the characteristics of quick bundling, good dielectric strength, locking and tightening, and easy use;

2. Due to the development trend of high-tech, various types of nylon cable ties have been frequently seen in people's daily lives to enhance their stretchability. But some nylon zip ties have poor compressive strength and flexibility. In order to better deal with this difficult problem, many companies have already been looking for solutions to this problem. In general, nylon cable ties have better cold resistance and the compressive strength of the material will significantly decrease. However, as a cable tie material, it is necessary to consider these two regulations separately. The selection of the proportion and type of toughening agent is to find a balance point between the two regulations and consider the requirements for nylon cable tie materials. However, adding toughening agents to nylon cable ties can also lead to a new challenge, reducing the fluidity of nylon cable ties and easily causing production and processing problems at the material level. At that time, it was necessary to improve the material lubrication management system and antioxidant management system to maintain the high fluidity and white color characteristics of nylon zip ties.

Nylon 66 itself has poor cold resistance, and it is normal for it to rupture due to cold temperatures in winter. If you want to solve this problem, you can add some raw materials that are cold resistant and have good compatibility with nylon 66. Or replace it with longer carbon chain nylon that is more cold resistant.

People have materials for handling nylon 66 cable ties that break in winter

You don't have to think that the beautiful and elegant particles in bags are authentic materials. Many of them are modified materials made from secondary plastic processing, and will undergo several high-temperature cutting and shaping designs,

The molecular formula of the raw material itself has undergone significant changes, and its characteristics have been reduced by more than half, coupled with dissolution and air oxidation during the period. Nylon zip ties also need to ensure their flexibility,

Generally, nylon has a water absorption capacity of 3-8% within its lifespan. When the molecular formula is damaged, no matter how it is steamed, other moisture absorption methods are useless, which determines its brittle fracture and may be prone to breakage;

The correlation between injection molding technology is also crucial for the convenience, simplicity, and practical operation of forming. By increasing the temperature of the material barrel and accelerating the injection molding time, product quality problems may occur with the zip ties themselves. The key points can be dissected to make the zip ties more visible, and some of them have cracks that are not fully filled inside.

There are many types of nylon raw materials available, so it is important to choose suitable soft materials such as single 6 and apply them in conjunction with each other; The injection molding process must strictly limit the improvement; Prevent excessive production and processing damage to raw materials. Overall, it is a targeted improvement in raw materials and injection molding processes.

Summary

Need to see the detailed situation. If it is a small-sized nylon cable tie, it is very easy to break if too much force and tensile strength are applied throughout the application process; If the normal tensile strength is not achieved, it is very easy to break, which is due to the poor quality of the zip ties themselves (some are made of recycled materials, while those made of granular materials are generally not easy);

That is to say, when used in areas with low average temperatures and relatively dry conditions, ordinary cable ties are very prone to breakage (due to the brittleness of the cable ties at this time and the faster outflow of water). When selecting, it is also necessary to inform the manufacturer of the natural environment and choose cable ties with stronger extensibility.
