Customer's story sharing:
SUNBOW varnish coated fiber glass flexible sleeves, as long as customers visit the factory, none of them will not place an order

A well-known Japanese motor manufacturer used to buy some varnish coated fiber glass flexible sleeves locally, and then imported some supplements from the United States. However, with the development, the number of orders has increased, and the required varnish coated fiber glass flexible sleeves have also increased. However, the local production conditions are limited, and the import costs from the United States have become expensive day and night, so they are looking for alternative suppliers in the Chinese market. I inspected no less than 10 varnish coated fiber glass flexible sleeves manufacturers, some samples failed the first round of testing, and some barely survived the first round, but they also ended one by one when they were audited by the factory. The customer was distressed, but never found a replacement manufacturer.

Soon after returning from the beginning of the year, their market development manager Andy saw our website on Google and sent a direct mail to SUNBOW to inquire about varnish coated fiber glass flexible sleeves. After several communications, I learned about the customer's requirements for fiberglass sleeving, recommended corresponding products, provided technical parameters and report references, Andy confirmed with their internal engineers, and reported that SUNBOW's varnish coated fiber glass flexible sleeves met their needs. , Decided to take a sample test.

Within 2 days, we will arrange the samples to be sent. Andy was very surprised. From previous experience, it takes at least 1 week for other manufacturers to prepare samples, while SUNBOW only takes 2 days. Clients are more aware of SUNBOW's service. Next is the strict test period lasting 1 week. In mid-March, Andy gave feedback on the test report. As expected, all aspects of SUNBOW's varnish coated fiber glass flexible sleeves fully met their strict requirements, and some properties even far exceeded their psychological expectations. SUNBOW defeated 95% of the manufacturers and successfully passed the first round.

The Japanese have always been rigorous and demanding. Passing the sample test is just one foot. The second round of on-site factory audit is a hellish test. However, it is precisely because some customers see the factory and see the problems that are not normally seen, so that the varnish coated fiber glass flexible sleeves manufacturers can correct and upgrade. The agreed date for viewing the factory came on April 3rd, and a team of 5 people came from Japan, with an invincible and powerful aura. SUNBOW has been in the varnish coated fiber glass flexible sleevesing dustry for 12 years. There are countless customers who have visited the factory. They have sufficient experience and strength. Facing them in the best state is the greatest respect for customers.

With up to 2 days of rigorous factory audit time, from documents to production lines, from quality department, production department to warehouse department, SUNBOW has met the requirements of its customers as a supplier in all aspects. The customer was very excited, and finally found the right person and found the right varnish coated fiber glass flexible sleeves manufacturer. Some manufacturers barely passed the second round of factory audits and needed improvements. Customers no longer considered them and directly chose SUNBOW to become their first-tier supplier. SUNBOW entered the customer's system and now supplies them with large quantities of varnish coated fiber glass flexible sleeves every month, and there has never been a quality accident during this period.

Why can SUNBOW beat 99% of the manufacturers, and customers do not hesitate to order varnish coated fiber glass flexible sleevess after visiting the factory?
1) SUNBOW has passed the ISO 9001:2015 management system, and strictly implements the management system every day according to the requirements. The production outlook substantially exceeds that of the peers, and the rigorous and meticulous production line is more than a few streets beyond the peers. Although some varnish coated fiber glass flexible sleeves manufacturers have passed the certification, they have been fishing for three days and drying the net for two days, and they simply can't hold on.
2) After the ISO 9001:2015 management system, SUNBOW also passed the IATF 16949 quality management system certification, reaching the IATF 16949 stringent quality management system standard. Because of this, coupled with high-quality glass fiber tubes, SUNBOW has successfully matched the drive motors of Mercedes-Benz new energy vehicles. In the fiberglass sleeving industry, most of the peers can't do this. They can only look back, but cannot surpass it.
3) In terms of product quality, SUNBOW uses alkali-free glass fiber yarn that has a lifespan of up to 2 times that of its peers. The whole production process is precisely woven by a fully automatic high-speed braiding machine. The outer layer is coated with a large-scale high-temperature resistant silicone oil from abroad. The proprietary process developed by the team substantially exceeds other peers.

The quality of SUNBOW varnish coated fiber glass flexible sleeves is irresistible.
