When the peer companies are still urging the mass production of the marking tube to deliver household electronics, the SUNBOW marking tube has been designated by the Mexican factory for application. Environmental protection, halogen-free, low-smoke and low-carbon life, SUNBOW is also helping.

The marking tube is already a traditional heat-shrinkable insulating material. As far as South China is concerned, there are not hundreds of marking tube manufacturers. However, when the customer applies the marking tube to rail transit, communication, and precision instruments, the testing of competing marking tubes in the same industry all fail to meet the standard. SUNBOW has been cultivating insulating sleeves for 18 years. When our marking pipes were tested by customers, the customers were also surprised and immediately emailed me and asked: "Why are only your SUNBOW marking pipes able to undergo long-term high temperature shrinkage, insulation and flame retardant properties? Does performance decline?"

For SUNBOW's partners, we generously share our production process, which is transparent and professional, so that our customers can use SUNBOW logo tubes with peace of mind and peace of mind. The production process of marking tubes is mainly divided into extrusion-irradiation-packaging. The process seems simple, but if there is no real effort, it is impossible to produce high-quality marking tubes, which is for sure. Speaking of this, I have to mention SUNBOW's unique technology. This process optimizes the raw material particles of the marking tube, increases the tensile strength, improves the elongation at break, and also increases the flame retardant coefficient. Many husband-and-wife manufacturers can just squeeze out. I already remember that I was on the production line in the factory during the internship period. The production supervisor explained to us in detail that squeezing is very important and will affect the size of the size. Irradiation is very important and will affect the function of shrinkage, and the absence of any condition will affect the performance of the product. Every job must be operated in accordance with the standards, and the quality comes from the strict control of every link.

Many customers will also ask, is the key index affecting the performance of the marking tube determined by the raw material? Raw materials do play a key role. SUNBOW chooses the raw materials of the marking tube, and will not reduce the quality requirements because of the unit price. The use of inferior and unqualified products will be eliminated, and the risk will be curbed at the source. What we are doing at the same time is that the machine is equipped with a unique formula, and thousands of data behind it support the high-quality formula, which makes the quality of SUNBOW marking tube always one step ahead of its peers.

The SUNBOW marking tube has been delivered to the customer's trial order. Now the Mexican customer engineer has a new regional production line. They are all designated to purchase the SUNBOW marking tube. Thanks for the recognition and support of the customer engineer.

Even though heat-shrinkable insulating sleeves such as marking tubes and heat-shrinkable tubes stand out and are highly praised by insulation management engineers, the current shipments of SUNBOW marking tubes are still young, and they are still designated for new energy vehicles, communications 5G or 6G, and military-grade equipment. in application.

All industrial equipment has used SUNBOW's logo tubes, and the quality must be excellent. Welcome to place an order for trial production.
