Kato Nishiko is an international purchaser of a well-known Japanese automotive wiring harness factory. Before the epidemic, their company mainly purchased double-wall heat shrinkable tubes from Sumitomo Japan. After the outbreak of the epidemic in 2020, the prices of various raw materials have continued to rise, and the prices of polyolefin raw materials used in double-wall heat shrinkable tubes have also continued to rise. Due to cost pressure, Sumitomo Japan had to increase prices for customers. The price increase was barely acceptable to customers, but what made Kato Nishiko unbearable was that due to repeated epidemics, the delivery time had not been guaranteed.

Helpless, customers had to go to China to develop new suppliers. It is a great honor that Kato Nishiko found Sunbow through a friend's introduction. The customer introduced their end customers in detail and let us know that they supply Volkswagen wiring harnesses and have very high quality requirements. At the same time, the customer introduced their requirements for double-wall heat shrinkable tubes in detail, and also sent Sumitomo's samples to us.

We are very happy after understanding the customer's requirements. Customers who have requirements are good customers. After receiving the customer samples, we compared the performance with our conventional double-wall heat-shrinkable tube for automotive wiring harness. After professional testing, Sunbow's special double-wall heat-shrinkable tube for automotive wiring harness is fully compatible with Sumitomo in terms of environmental protection and performance. comparable. We sent samples of Sunbow's conventional double-wall heat-shrinkable tubing for automotive wiring harnesses to customers. After half a year of testing, Sunbow's special double-wall heat-shrinkable tube for automotive wiring harnesses has fully met the performance indicators and can completely replace the Sumitomo brand. ( PVC tubing)

The same quality, Sunbow's price is half of Sumitomo's, and the delivery time is guaranteed. In the end, Kato Nishiko decided to purchase double-wall heat-shrinkable tubes for automotive wiring harnesses from Sunbow. Because of this project, she also got a promotion and a raise. ( silicone rubber tubing)

At present, there are many merchants selling double-wall heat-shrinkable tubes in the market. The price difference between high and low is too big, mainly because most of them are not factories. Even if some are factories, they are not completely self-produced. Most factories can only The extrusion process and the irradiation, expansion and gluing processes are all sent to powerful factories, and our Sunbow is one of only three domestic factories with one-stop production equipment and one-stop production capacity. .

Why Sunbow's 4x shrinkable semi-rigid heat shrinkable tube with glue for automotive wiring harness can win the affirmation of Volkswagen's wiring harness supplier AQ?

1. Sunbow adopts international big-name polyolefin raw materials, and the sleeves produced will have better expandability and shrinkage effects.

2. Sunbow is produced by imported equipment from Japan. Whether it is extrusion, irradiation or expansion, the tolerance range control of the inner diameter has reached the international standard and there is no wall deviation in shrinkage, which is comparable to the American brand Tyco.

3. Sunbow has a unique formula, and the addition of flame retardants is controlled in an appropriate ratio, so that the glued heat shrinkable tubes produced are not only flame retardant but also have better heat shrinkage performance.

The quality of the 4-fold shrinkable semi-rigid heat shrinkable tube with glue for Sunbow automotive wiring harness is comparable to the international first-line brands, and many of the world's top 500 are in use. Choosing the double-wall heat shrinkable tube for Sunbow automotive wiring harness is to choose high quality and safety.
