Anna is the purchasing manager of a large industrial motor manufacturer in Poland and an old friend of SUNBOW. We have cooperated with SUNBOW for more than 11 years. One morning in mid-January, I received an email from Anna with the subject line "Having a Big Trouble". After 11 years of email correspondence with Anna, this is the first time I have received such an emotionally urgent email from Anna. After reading it, it turned out that the wear resistance of the outer FIBERGLASS SLEEVE of a motor internal wiring harness of their company was not enough, and the customer complained. The boss asked her to solve the problem within a month.

After the communication, it was learned that the FIBERGLASS SLEEVE and the production of dewaxing part of the FIBERGLASS SLEEVE purchased by Anna were not completed by the same manufacturer, and now neither side admits that it is their own problem. The dewaxing section says that the semi-finished tube braid is too loose and not tightly braided. The weaving manufacturer also said that the high temperature used in the dewaxing process is the fundamental reason for the reduction of the wear resistance of the FIBERGLASS SLEEVE. Anna failed to communicate several times, and thought of SUNBOW. Due to the cooperation for many years,SUNBOW has never complained about the FIBERGLASS SLEEVE it has supplied in 11 years. She hoped that SUNBOW could help to find out which link went wrong. ( PVC tube)

In less than a week, I received the FIBERGLASS SLEEVE sample sent by Anna. After analysis, the engineer found that the FIBERGLASS SLEEVE supplier that Anna is currently cooperating with was actually using glass fiber yarn with high alkali content for weaving. There are also problems in the process. The overall weaving method adopts the pulling process, which leads to the loose density of the FIBERGLASS SLEEVE and the braided tube. Not only that, in terms of dewaxing, the temperature is too high, which greatly reduces the wear resistance of the FIBERGLASS SLEEVE. Anna reported the problem to the original FIBERGLASS SLEEVE manufacturer, but the other party needed time for rectification and development, at least 2 to 3 months. The time limit given by the boss is 1 month, how can this be waited for. (silicone tube)

SUNBOW has its own strong R&D team, independent research and development of formula technology, in the wire insulation protection of matching motor coils,SUNBOW FIBERGLASS SLEEVE is already familiar. The customer's requirement is a FIBERGLASS SLEEVE with ultra-high wear resistance. Knowing the key problems, there are ways to solve them. Knowing the requirements of Anna's wear coefficient,SUNBOW engineers came up with the involved plan 2 days later. It took less than 2 weeks for SUNBOW to discuss and develop the latest technology, and to send samples to customers for testing. As expected, the wear resistance of SUNBOW's FIBERGLASS SLEEVE fully meets the customer's motor requirements, or even better. After the complaint was resolved, the boss was also happy and asked Anna to place all orders for fiberglass sleeves to SUNBOW in the future, and not to separate them again.

Why can SUNBOW FIBERGLASS SLEEVE achieve such excellent wear resistance? What are the unique features of SUNBOW fiberglass sleeves that make customers choose without hesitation?

1. Key raw materials.SUNBOW uses high-quality alkali-free glass fiber yarn, which is finely woven into the semi-finished product of the peg. The semi-finished products woven by alkali-free yarns have the best toughness. Many domestic FIBERGLASS SLEEVE manufacturers are well aware of this. However, in order to reduce costs and make huge profits, they use low-quality alkali-alkali yarns for weaving.

2. Production process. In order to improve the wear resistance of FIBERGLASS SLEEVE,SUNBOW adopts independent research and development technology, and the dewaxing process reduces the temperature and does not completely dewax.

3.SUNBOW fiberglass pipe has 1.5 times higher temperature resistance, 2 times higher wear resistance and tear resistance, and more than 2 times higher service life.

SUNBOW fiberglass tube, irresistible ultra-high texture, customers who have used it will only return the order and will not regret it.
