In July 2022, Mr. Gao, the purchasing representative of a leading auto parts

company in Japan, contacted us through an old customer of SUNBOW. After the telephone communication, Mr. Gao attached detailed product specifications and drawings, and looked for glass fiber casing products. The requirements are very strict and the following points are listed:

1.Material glass fiber + coating (outer rubber inner fiber)

2. Specification ID30mm wall thickness 0.9+/-0.10mm

3. Fire test After passing 13L/min of coolant, flame spray at 1000℃, no leakage for 60s, the melting point of PA12 of the protected pipe is about 180℃.

After repeated communication and understanding of customer needs, I learned that customers looking for glass fiber sleeves to apply to high temperature water pipes should not be damaged by flame spray for 60S, and there should be no rupture. According to Mr. Gao's requirements for glass fiber sleeves, I asked him Recommend SUNBOW7KV silicone fiberglass sleeve and send free samples on customer expedited express. Silicone fiberglass sleeve is a product with high flame retardant wear resistance and tear resistance, and has been delivered stably for many years.

After 5 days, I received a call from Mr. Gao. Their technical team tested the color fiberglass sleeve. Almost every parameter withstanding voltage and chromaticity was 20% higher than other insulating sleeve manufacturers. Sunbow is also his company. Contact all insulation casing manufacturers, the only one that can pass the test at one time. Next, is the very smooth order confirmation process for fiberglass sleeves.

SUNBOW glass fiber sleeve, with an average breakdown voltage of 1.5KV-7KV without breakdown, has ultra-high compatibility, wear resistance, flame resistance, acid and alkali corrosion resistance, heat resistance, pressure resistance and excellent chemical properties.

Sunbow uses a high-speed braiding machine to weave. The high-speed braiding machine is not only faster than the ordinary braiding machine, but the blank tubes produced by it are all ejected, and the frequency of changing lines is reduced, so that the joints are 35% less than that of the ordinary braiding machine. The glass fiber sleeve has better tear resistance.

The reason why Sunbow glass fiber tube has such superior comprehensive performance is that it adopts high-quality alkali-free and wax-free high-strength glass fiber yarn, which has good toughness. The surface is flat, which lays the foundation for the subsequent coating process. Coupled with a proprietary process formula, the quality foundation of the fiberglass tube is guaranteed.

Mr. Gao understands why Sunbow's samples are all successful at one time, because Sunbow can easily solve this glass fiber sleeve with high tear resistance and no color difference. The raw materials are German Wacker glue, I think it will not Playing with materials, thinking what customers think, worrying about what customers are worried about, every time it is a one-time proofing success.

Sunbow successfully entered the customer's supplier system and became the customer's designated supplier after several months of mass trial production.
