Sunbow heat shrinkable tube can customize personalized products according to customer needs, excellent quality and professional production technology, successfully won the domestic well-known heater enterprises, and become the exclusive supplier of X-force air conditioners.

          At present, there are countless large and small enterprises and traders of double-wall heat shrinkable tubes in China. Some small manufacturers use refurbished materials for production for profit, maliciously competing at low prices, and the industry is chaotic. Such double-wall heat-shrinkable tubes have no quality assurance and their performance is not up to standard. Some small workshops are unstable in technology, and the inner diameter, wall thickness and shrinkage rate of products cannot be controlled well. The existence of these problems is really a headache for customers. ( PVC tube)

In October 2019, Ms. Zhang, the purchasing manager of X-force air conditioner, contacted us. At that time, they had a newly developed air conditioner project that needed heat shrinkable tubing. Before finding Sunbow, they had tried many well-known domestic and foreign insulating sleeve suppliers. However, after testing and verification, the sample results are not very optimistic. The wall thickness and inner diameter of the product cannot be fully matched with the temperature sensor, and some cannot meet the performance standards. The certification materials in all aspects are incomplete and cannot be guaranteed. When the project reached the trial production stage, the project was suspended due to poor product pass-through rate and performance stability.

  After a detailed discussion with the customer's purchasing manager, to understand the location of the customer's products, the specifications and performance requirements of multiple products, we recommend the use of 3 times shrinkable heat shrinkable tubes, and use heat shrinkable tubes according to the customer's heater. The location, size and shape of the shrinking tube require special customized dimensions. Miss Zhang will take samples for testing after listening. On the same day, each of our teams immediately launched a seminar to make a customized plan, and communicated it to each department. The sample was made and submitted to the customer within three days. ( silicone tube)

2 days after Ms. Zhang received the sample, she sent a good news that the sample test passed. The inner diameter and wall thickness before and after shrinking are very suitable, and the properties such as flame retardant, temperature resistance, and insulation are fully up to standard. The new project has finally developed further. Immediately placed an order for 100,000 pieces of trial production, and the direct pass rate of the product was 99.9%. The project was successfully carried out in November last year. At present, the consumption of double-wall heat shrinkable tubes has been very stable, with an annual consumption of 5 million pieces.

Since its establishment 17 years ago, Sunbow has been adhering to the concept of quality first, the raw materials used must be first-line brands, the production process must be developed by itself, and the production equipment must be advanced with the times, so that there is an exclusive process formula for heat shrinkable tubes. Customized customer requirements can be guaranteed to be met 99%. Sunbow heat shrinkable tube is not only high quality, but also surpasses all its counterparts. The products meet the environmental protection aspects of ROHS2.0 and SVHC (REACH), and the flame retardant meets the test requirements of UL224 (VW-1).
