Customer's story sharing

SUNBOW  Expandable Fibreglass Sleeve are made of extraordinarily large diameter and not partial to oil. A well-known American home appliance placed an order after visiting the factory

SUNBOW  Expandable Fibreglass Sleeve can not only make the minimum size of 0.5mm, but also those with an inner diameter greater than 16mm, while the maximum inner diameter of the peer can only be 15mm. SUNBOW  Expandable Fibreglass Sleeve, assisted by a large tube braiding machine, produces large specifications that cannot be achieved in the same industry. If you want a  Expandable Fibreglass Sleeve with a large inner diameter, which is not partial to oil and has stable voltage performance, the only one you can find in China is SUNBOW.

There are many manufacturers of  Expandable Fibreglass Sleeve in the domestic market, but most of the industry's  Expandable Fibreglass Sleeve can only achieve the maximum inner diameter of 10mm, and the largest is only 15mm. Many manufacturers claim that their  Expandable Fibreglass Sleeve can achieve an inner diameter greater than 15mm, but it is only a verbal publicity, and the production equipment simply does not have such a large braiding machine. Without basic equipment, how can it be possible to produce large-sized fiberglass sleeves? SUNBOW not only has automatic high-speed large tube braiding machine as the assistance, it produces large specifications that the peers cannot do, but also the insulation performance of large-format  Expandable Fibreglass Sleeve is still the same and stable, and it has been supplied to world-renowned household appliances companies in batches. The product has been tested and verified by customers for a long time, and its stability and reliability have been fully guaranteed.

In June 2019, an engineer from a well-known home appliance company in the United States found from the Internet and consulted on the fiberglass casing, requiring a large size 18mm to be used on the water heater. The customer emphasized that this specification is very important. The customer has already taken glass from many manufacturers before. The fiber casing samples were tested, but the inner diameter did not meet their requirements. The small size did not fit into the product, and some could barely fit in, but the layer was too oily and the voltage performance was unstable. Knowing that SUNBOW has supplied fiberglass sleeves to many world-renowned electrical appliance companies, I immediately visited the factory.

On the day of the factory visit, the customer was surprised to see more than 600 high-speed knitting machines on the first floor of the workshop. Among them, he visited the large-tube high-speed knitting machine. The inner diameter was measured on the spot to show the customer. The inner diameter was 18mm. The breakdown voltage test was also carried out in the laboratory. The voltage rose step by step from 1.2KV to 7KV. There was no breakdown or rupture on the surface, which proved that in the case of large specifications, the SUNBOW  Expandable Fibreglass Sleeve is not oily and has super performance. stable. The customer is very satisfied. Now the internal insulation project of the water heater has been introduced and mass production has begun.

SUNBOW fiberglass casing has the following advantages:
1) The key raw materials are imported from big brands abroad, combined with a proprietary process formula, to lay the foundation for the quality of  Expandable Fibreglass Sleeve in the top 3 in the industry.
2) The temperature resistance is 1.5 times higher than that of the same peer, the wear resistance and tear resistance are twice that of the same peer, and the service life is more than twice that of the same peer.
3) With the aid of the large-tube high-speed braiding machine, combined with the proprietary process formula, it can produce large specifications with an inner diameter greater than 16mm that the peers can't do, without partial oil, and stable performance.

If you want large-size  Expandable Fibreglass Sleeve, it is not oily and has stable performance. Only SUNBOW can trust in China.
