Customer case
If you want a good glass fiber tube, you can only go to SUNBOW to pay the bill in China.

I am very confident to say that SUNBOW's glass fiber pipes have no competitors in the domestic market. If you want to manage the glass fiber tube well, you can only go to Shunbo to pay for it.

Many domestic counterparts say that they have super tear-resistant and super-wear-resistant fiberglass tubes, and they fool customers into saying that they do not break at all. In fact, they are deceiving customers. As long as they are tested by customers, they will be full of loopholes immediately. Only after numerous comparative tests can we prove that only SUNBOW's glass fiber tubes are really good tubes and truly invincible.

Zhejiang Ningbo Yiyi Transformer Co., Ltd. found us through the introduction of a friend. He heard from his friend that the quality of our Shunbo fiberglass pipe is very good. He asked if we can provide super tear-resistant and super-wear-resistant fiberglass pipe, which requires a force of 6.9g. /d or so, we say yes. The customer said that he should not be in a hurry to make promises, because he has found several suppliers, but the results are not satisfactory. The customer emphasizes that it does not break at all during use, and requires high wear resistance and strong tear resistance.

We understand the customer's requirements. The characteristics of this glass fiber tube focus on the quality of the raw material yarn and the preparation of silicone oil. The customer said that they used a counterpart in Dongguan before. The transformer was damaged within a few times, and the voltage dropped so much that the inside of the transformer conduit could not be insulated. The customer's transformers are all exported to Europe and the United States, so there is no way to ship them now, and there may be a risk of returning the products sent out earlier.

According to the customer's application requirements, we recommend SB-SGS-40 in the glass fiber tube series. The tensile strength is 6.3~6.9g/d. The next day, we sent a sample of several meters to the customer for testing. The customer tested it for several days, including more than 245 hours of burn-in, which is more demanding than ordinary transformers. At the same time, 2 peers also sent samples. As soon as the results came out, only SUNBOW's samples passed the test. The customer immediately decided to switch to Shunbo's glass fiber tube for all products. So far, there have been no quality complaints in nearly 2 years of mass production.

SUNBOW is one of the few manufacturers in the industry that uses fully automated yarn beating machines, high-speed braiding machines and fully automated pipe-passing machines to produce glass fiber tubes. It improves the production efficiency, ensures the consistency of products, and also implements the system requirements of IATF16949.

Sunbow's glass fiber tubes have been supplied to Mercedes-Benz, Huawei and other well-known enterprises in batches, and are now a well-known brand in China. If you want to manage the glass fiber tube well, you can only go to Sunbow to pay for it.
