Customer's story sharing
SUNBOW Silicone Fiberglass Sleeve Tube, no bubble and burr, Vietnamese customers can't put it down and return the order again
The produced Silicone Fiberglass Sleeve Tube is bright and smooth after being coated with silicone oil, without air bubbles and burrs. It has always been a rigid indicator of SUNBOW's strict control. It has never dared to slack off for 16 years. SUNBOW dares to ensure the stability of each batch of Silicone Fiberglass Sleeve Tube, and the surface is bubble-free and fuzz-free. Most of the domestic counterparts, I am afraid, do not have the confidence and courage to promise this. Because of this, more than 30 world-famous enterprises have not hesitated to choose SUNBOW, Silicone Fiberglass Sleeve Tube, and only specify SUNBOW to produce. Colleagues can only envy, but cannot surpass and replace.
Hong is the head of procurement in China for a well-known industrial motor manufacturer in Vietnam. An old customer he met has an annual increase of more than 20% in orders. However, starting from June 2020, Hong found that the number of orders from customers has begun to drop a lot. Ask the customer whether it is due to the impact of the epidemic that the order volume has dropped? But the result is not. Later I learned that the customer was not very satisfied with the fiberglass sleeving supplied by the existing fiberglass sleeving manufacturers. Existing manufacturers' glass fiber sleeves are very unstable between batches, and the finished products repeatedly have bubble burrs. Seeing that the order volume has dropped, they will be replaced by them, and Hong is so anxious that he can't sleep at night.
Hong asked all the Silicone Fiberglass Sleeve Tube manufacturers in his hands. No single factory dared to guarantee the stability of each batch and ensure that each batch of Silicone Fiberglass Sleeve Tube was free of air bubbles and burrs. Through a factory introduction, Hong found SUNBOW and expressed his worries and customer requirements for fiberglass sleeving. Explain to customers that 95% of domestic manufacturers attach importance to the temperature resistance, pressure resistance, softness or tear resistance of Silicone Fiberglass Sleeve Tube, but often ignore the control of the resin coating on the surface of the Silicone Fiberglass Sleeve Tube. Without technical support, the controlled resin coating fluctuates, and there is no guarantee that the outer layer of the glass fiber sleeve will be free of air bubbles and burrs. This is what many domestic Silicone Fiberglass Sleeve Tube manufacturers lack.
Hong looked at our product parameters and pictures, bought a few rolls of samples and went back to test. About half a month later, Hong received an order for fiberglass sleeving. After talking, it was learned that the customer was even very satisfied with the fiberglass sleeving of SUNBOW. The surface coating of SUNBOW Silicone Fiberglass Sleeve Tube is bright and smooth, completely free of air bubbles and burrs. Compared with other manufacturers, it instantly caught people's attention and stood out from the crowd.
The first order was shipped to Hong in less than one month. This week, Hong placed another return order worth more than 10,000 US dollars. Hong reported that the stability of all aspects of the first order of SUNBOW Silicone Fiberglass Sleeve Tube was beyond their imagination. The first order and the sample test belong to different batches, but as usual, the SUNBOW fiberglass sleeving has no bubble burrs on the surface, which can testify to how strong the stability of the SUNBOW fiberglass sleeving is between batches. Customers love SUNBOW fiberglass sleeving, and orders only specify our factory to produce. With the use of SUNBOW Silicone Fiberglass Sleeve Tube, Hong's own motor orders in a quarter have soared more than two times, and the end customers' evaluation of him is very high. Hong is also more confident as he goes on.
SUNBOW fiberglass sleeving is absolutely different from others:
1) The semi-finished tube is made of high-quality alkali-free glass fiber yarn, and the self-developed top process is used for weaving, which greatly reduces the burr problem caused by the weaving of the tube. In order to reduce the cost and investment, most of the peers use low-quality mid-alkali yarn weaving. Moreover, the process is still in the weaving process of pulling.
2) SUNBOW has introduced more than 600 advanced high-speed braiding machines for fine-knitting Silicone Fiberglass Sleeve Tube pipes. And most of the peers are still in the age of the old semi-automated knitting machine, the friction coefficient is large, how can there not be many burrs in the semi-finished products?
3) After the tube is formed, it is different from the direct high-temperature coating of other manufacturers. SUNBOW uses a fully automatic high-speed scraper to scrape off the remaining burrs on the tube, which fully ensures that there will be no bubbles due to burrs during coating. problem.
More than 20 of the world's top 500 companies have chosen SUNBOW Silicone Fiberglass Sleeve Tube.
