Do you know how to knit PET Braided Sleeve?

With the rapid development of computer simulation, the problem of electromagnetic leakage and impact has become increasingly prominent. PET Braided Sleeve mainly have mechanical protection and interference signal shielding functions. The PET braided sleeve is laid on the surface of wires and cables, which is a shield to prevent electromagnetic leakage and impact. Loss of maintenance is an important maintenance method in modern warfare to prevent nuclear magnetic resonance attacks from paralyzing communication systems. Different uses have many other requirements for Pet Braided Sleeve, such as; weldability, heat resistance, corrosion resistance, Anti-oxidation, conductive properties, flame-retardant PET woven sleeves, excellent shielding properties, light weight, low cost, etc.

In response to these problems, many PET Braided Sleeve manufacturers have stipulated the industries and corresponding performance requirements for PET Braided Sleeve. They have developed products with lighter weight and New PET Braided Sleeve with good softness, good heat resistance, high strength and high knitting density can meet the requirements of different uses.
There are currently two types of high-speed knitting equipment in China. One is the spindle weaving method. The spindle structure is more complicated and oil stains on each part can easily pollute the product. The advantage is that the weaving speed is fast, but the output The rate is lower; the other is the flying goose ("8" shape) knitting method. Each part is distributed under the spindle to avoid damage from oil stains. The speed is basically the same as vertical knitting. Nowadays, the knitting machines developed by China can basically reach production and manufacturing.
There are two protective pads under the fall-type braided pitch gear, which will cause deviation during weaving. It is modified to reduce the relative height of the protective pads and add one protective pad, thereby Improve the gear meshing to ensure the control of the pitch diameter, improve the take-up support force, and improve the consistency of the expansion and contraction angular speed.
The material selection is to achieve the function of preventing electromagnetic wave leakage or anti-interference of PET Braided Sleeve, while at the same time achieving performance indicators such as weldability, flexibility, light weight, oxidation prevention, heat resistance and high toughness. Yunhai High-tech uses four raw materials: tinned copper core wire, electroplated nickel copper core wire, tinned alloy copper wire and tinned copper-clad steel wire, and determines the corresponding wire apertures of 0.1mm and 0.12mm respectively. Specifications and models: Compared with past processing techniques, the wire is thinner.
The reduction of wire diameter during the research and development process places higher demands on the weaving process. Because the wire material is thin, it is easy to cause belt breakage during the weaving process. The doubling shaft tool was changed to a winding reel, and a special doubling wire was selected. The single-stranded machine is used for laying out the wire. At the same time, the tooling fixture of the doubling machine is changed to one that can install 48-spindle wire tubes. The doubling stroke arrangement is adjusted and the doubling pitch diameter is adjusted again. This method can improve the doubling support force. Even and consistent, no "pressing" phenomenon.
According to the production speed of PET Braided Sleeve, the take-up brake pads are appropriately adjusted to keep the take-up speed ratio consistent with the pitch gear speed. In order to ensure that the new PET Braided Sleeve is more conducive to cable threading, the friction of the car brake pad is reduced at the take-up rotating transmission gear, so that the take-up support force is reduced as much as possible, ensuring that the take-up support force is small and the product is not easily broken. It is beneficial for the wire breakage rate in the knitting process to be too high, resulting in unnecessary waste. The new PET Braided Sleeve knitted by this method have an "empty tube shape" and will not be compressed into a "flat shape" after wire arrangement, which is very beneficial to wires. Cable threading.
