Double-layer fiberglass tube, exclusive supply by SUNBOW, you can not find other suppliers in China
When it comes to fiberglass tubes, domestic products are all the same, all are single-layer fiberglass tubes. Only SUNBOW is unique in launching double-layer fiberglass tubes. Exclusive supply, you can't find other suppliers in China.
At present, the fiberglass tubes provided by domestic counterparts are all single-layer fiberglass tubes without exception. Some peers even changed the concept and called the thickened single-layer fiberglass tube as a double-layer fiberglass tube to confuse customers. However, SUNBOW developed such a double-layer fiberglass tube at the request of the customer, and the customer was 100% satisfied.
A customer of a certain brand of motors in Brazil has been searching for double-layer fiberglass tubes in the Chinese market for a long time. More than 95% of the suppliers can provide thickened single-layer fiberglass tubes, and the customers are not satisfied. The customer saw our booth at the Berlin Exhibition in Germany in 2016. The customer wants to use double-layer glass fiber tube insulation on a motor. Ask if we have similar sleeves. Single-layer glass fiber tube can be used as Base, add another layer. At that time, we did not have such a casing, and the entire industry had not heard of such a practice, and the cost would be high. Customers have found several suppliers in China, and they do not have similar double-layer fiberglass tubes, and can only use thickened single-layer fiberglass tubes for testing. However, even the thickened single-layer fiberglass tube is still thin. Once the motor rotates, it is easy to break, which leads to the need to re-thread the motor.
After understanding the customer's application, we promised the customer: "We can try to develop the customer's needs, but it takes a week." After a week, we submit two samples to the customer for testing, one is the thickened single layer on the market Fiberglass tube, cheap price and short delivery time. The other is double-layer glass fiber tube, which is expensive and has a long delivery time. However, both samples meet customer's application requirements. At that time, we were able to complete the research and development of a new type of double-layer glass fiber tube in seven days, and the performance reached the level of customer satisfaction, which was beyond our expectations. After testing, the customer finally chose this double-layer fiberglass tube, even if the price is expensive, the customer also chose it.

SUNBOW has a glass fiber tube SB-SGS-40 series, which is very suitable for high-voltage insulation of drive motors of new energy vehicles. The test was conducted at the Mercedes-Benz headquarters. After 30 days of continuous operation of the fiberglass tube on the lead of the drive motor, the fiberglass tube did not crack. Among domestic brands, only SUNBOW did it and eliminated all competitors.
Among the insulating sleeves for new energy vehicle applications, most manufacturers are currently competing in the project of driving motors, but SUNBOW has developed the SB-SGS-40 series first, and its advantage is that SUNBOW insists on using it. Alkali-free and sodium-free glass fiber yarn and a certain brand of silica gel imported from Germany. After the tube is formed by the special weaving process of SUNBOW, the glass fiber tube yarn is tight and moderate, and the surface is smooth, which lays the foundation for the subsequent coating process.
The toughness of German silicone raw materials is more than twice that of domestic silicone. With the help of a proprietary formula, the coated glass fiber tube has a brighter color, and its wear resistance and tear resistance are more than twice higher than those of the same industry. The temperature resistance reaches 260 degrees, and the temperature resistance of domestic counterparts is 200 degrees.
The SB-SGS-40 series are mostly used in new energy vehicles. Therefore, there are not many domestic manufacturers with its production capacity. Many customers who find SUNBOW value whether the manufacturer has large-volume production capacity. SUNBOW has two factories in Shenzhen and Dongguan, with an output of 8.4 million meters per month. This is in a far leading position among domestic counterparts.
At the Berlin exhibition in Germany in May 2019, the technical director of Mercedes-Benz headquarters directly tested the wear resistance and tear resistance of the SUNBOW fiberglass tube on the spot and found that the SUNBOW fiberglass tube exceeded many domestic and foreign manufacturers. At this time, the customer has already seen the capabilities and strengths of SUNBOW, and used SUNBOW fiberglass tubes in a recent new energy vehicle drive motor project.
A German charity company, specializing in the production of $1 glasses, brings beautiful experiences to 150 million people in developing countries every year. The protective layer of the outer layer of the eyeglass frame is the use of SUNBOW bright PE heat shrinkable tube, so this German charity company praises our technological innovation and breakthroughs.
There are various manufacturers of PE heat-shrinkable tubes on the market, but most manufacturers are flame-retardant PE heat-shrinkable tubes, because more than 90% of customers only purchase flame-retardant PE heat-shrinkable tubes. SUNBOW considers customers in all aspects. As long as there is customer demand in the market, SUNBOW will develop and produce. This kind of non-flame-retardant heat-shrinkable tube is generally bright in appearance. Because there are fewer contacts, many manufacturers are actually not very familiar with this type of product.
When this charity company in Germany found our company for the first time, customers actually knew quite a lot about these products. I remember clearly that the inquiry sent by the customer directly said that it should be 100% pure PE material, not flame retardant, no glue, and the shrink ratio is 3:1, even the inner diameter, wall thickness tolerance and shrink size are all The list is very clear.
At that time, I was also the first to contact this kind of product, because the non-flame-retardant heat-shrinkable tube usually only has a 2:1 shrink ratio, so I recommend the customer to the flame-retardant 3:1 heat shrink without glue tube. After the first sample was sent, the customer was not satisfied after the test, saying that the surface of the tube was not bright and it was flame retardant. So I sent the customer's request to the engineer and told me it was applied to the glasses frame. After in-depth research and development of the product, a 3:1 bright surface heat shrinkable tube was sampled. After receiving the samples and testing, the customers were very satisfied with the results. They had their first order, and many color tubes were added, and the number of orders was increasing.
SUNBOW produces heat-shrinkable tubes of various materials, adheres to the four principles of "quality, cost, delivery and service", so that customers are satisfied with our products and services. In the same way, every technical requirement of the customer strives to surpass, so that the customer has unexpected surprises. Every time you get a satisfied product that is better than once, the customer will never give you up easily. During the seventeen years since SUNBOW opened the factory, it has accumulated a large number of loyal customers with satisfied products.
SUNBOW silicone cold shrink tube has been used in 5G base stations, installation is twice as fast as peers
For the big market of 5G base stations, although many silicone cold shrink tube manufacturers continue to increase research and development efforts, few manufacturers can really install silicone cold shrink tubes quickly. It is very confident to say that SUNBOW silicone cold shrink tube is currently the only product in China that can be quickly installed, and it is twice as fast as its counterparts.
The vast majority of silicone cold shrink tubes made in domestic factories have practically no difference in performance. Because silicone cold shrink tubes are made of special silicone rubber materials, the only difference is the installation problem. The silicone cold shrink tubes manufactured by more than 80% of the factories are as follows:
1. Need to push the cold shrink tube to the root of the joint as much as possible, and start to carefully pull out the support bar;
2. Push the cold shrink sleeve towards the root of the joint while pulling the support core rope, and observe at the same time until the cold shrink sleeve is firmly contracted at the joint root of the joint;
3. Do not push, pull or shake the cold shrink sleeve afterwards, otherwise the shrinkage may not be firm or damaged;
4. If the drawing is not smooth, do not force it, you should complete the installation of other cold shrink sleeves.
The matters needing attention during installation are as follows:
1. It is strictly forbidden to wrap the cold shrink sleeve when it is installed, otherwise it will easily cause the water inlet and waterproof failure;
2. Use a wrench to tighten the adjacent connector where the shrink sleeve joint is installed, otherwise it will cause damage to the shrink sleeve.
SUNBOW understands that users spend a lot of energy and time when installing the silicone cold shrink tube, so they developed a silicone cold shrink tube that simplifies the installation. You only need to pull the silicone cold shrink tube to support the entire installation process. The installation time is twice as fast as its counterparts, and there will be no installation errors caused by functional aging or damage.
