Purchasing corrugated pipes for 6 consecutive years, Turkish customers recognized the quality and softness of SUNBOW
Although Turkish customers took samples of corrugated pipes from many Chinese manufacturers, the hardness test results of corrugated pipes could not meet customer requirements. Each corrugated pipe sample still felt so hard and not soft enough. The only thing that can make customers applaud and applaud is SUNBOW's bellows, not only in quality, but in softness that customers want, even beyond. Because of this, Turkey has been purchasing for 6 years now.
In the insulating tubes industry, manufacturers know that the higher the required flexibility, the more difficult it is to produce insulating tubes. Because the softer the tube, there is not enough technical support when extruding, not only the thickness deviation is large, but also it is easy to fail to form, and the same is true for the corrugated tube. This problem has always existed in the insulating tubes industry, and it is a pain point that 99% of domestic manufacturers have been having a headache but cannot solve.
Winter, a Turkish customer, is the purchasing manager of an internationally renowned wire harness manufacturer in the Asia-Pacific region of Shanghai. Every year, he purchases large quantities of insulating tubes for wire harness protection for the headquarters Turkey in China. Previously purchased from SUNBOW were PVC pipes, braided mesh pipes and other products, but never purchased corrugated pipes, because they had a stable supplier of corrugated pipes before they knew SUNBOW, and they did not plan to change them. Shortly after returning from work in the New Year, I received Winter's SOS on WeChat, saying that he was dying of annoyance. After working together for so many years, I have never seen Winter so troubled.
After the conversation, I learned that it was about the supply of bellows. Their Turkish headquarters has new requirements for corrugated pipes. The softness of corrugated pipes is more excellent than usual, and the better the softness, the better the new wiring harness products of the headquarters. Andy also asked the original bellows supplier for help at first, but after several proofing, it ended in failure. After that, I found several well-known bellows manufacturers in China, and the samples sent in the past were all so hard. Later, I asked whether the hardness of the bellows could be customized to make the bellows softer, but the problem was nowhere to be found, and no manufacturer could guarantee it.
After inquiring about the customer's requirements for hardness, the data was obtained. After analysis by SUNBOW's strong R&D team, the customer received the sample in less than 5 days. The SUNBOW team only took 2 days to do the sample, and the remaining 3 days was the time for logistics delivery. Customers get the samples and try the hand feeling. The softness is what they need, but the specific test results have to wait, but Winter said that it is inseparable. As expected, SUNBOW Bellows did not disappoint anyone.
Why can SUNBOW customize the hardness of bellows and get the recognition of customers?
1. Raw materials are the key. SUNBOW does not use simple PE, PP or nylon materials to produce corrugated pipes, but according to customer requirements, it develops special materials and uses its polymers to lay a foundation for more excellent softness of corrugated pipes.
2. Strong R&D team technical support. SUNBOW has its own strong R&D team, which is incomparable with peer manufacturers, and has a fully equipped laboratory. SUNBOW has already realized the customized products that can meet the needs of customers. And most manufacturers do not have such team support, and do not have such technical ability to complete.
3. The softness is 1.2 times higher than the counterparts, the electrical insulation is 1.3 times higher than the counterparts, the flame retardant performance is 1.4 times higher than the counterparts, and the service life is more than 1.5 times higher than the counterparts.
Bellows, customers who have tried samples will only fall in love with them and will not be able to beat them away.
