After more than a year of hard work, Sunbow’s fiberglass sleeving passed the performance test of Mercedes-Benz new energy vehicle drive motors, and mass production began in October 19th. Sunbow has become the designated supplier of Mercedes-Benz new energy vehicle drive motors. At present, Sunbow’s fiberglass sleeving is supplied to Mahle. Mahle is a manufacturer that specializes in supplying drive motors to Mercedes-Benz cars, which means that Sunbow’s fiberglass sleeving successfully knocked on the door of the "three electricity" field of new energy vehicles.

The drive motors of new energy vehicles have particularly high requirements on the wear resistance and tear resistance of glass fiber sleeves. The fiberglass sleeves of Sunbow have passed the test of Mercedes-Benz headquarters. The test requirements are the glass sleeved on the drive motor leads The fiberglass sleeve does not crack when the motor rotates continuously for 30 days. Our Sunbow’s fiberglass sleeve has undergone two formulation improvements and three times sample submission . It passed the test of the Mercedes-Benz headquarters for a total of one year and two months and reached the customer's requirements. This sense of accomplishment cannot be described in words. Other peers are out of reach.

Why did Mercedes choose Sunbow’s fiberglass sleeving?

In the selection of materials, Sunbow insists on choosing alkali-free and sodium-free environmentally friendly glass fiber yarn and Wacker imported silica gel from Germany. Most of our colleagues choose domestically produced silica gel. Its insulation and flexibility are far from Sunbow’s.

In terms of technology, Sunbow’s fiberglass sleeving insists on using self-developed formulas, so that we can customize suitable formulas to meet specific performance requirements for customers according to their use requirements, but most of our colleagues are the same. Meet the unique performance requirements of customers.

In the production equipment, Sunbow's glass fiber sleeves are produced by fully automatic high-speed weaving machine, sanding machine, pipe machine and coating machine, which greatly reduces the artificial quality abnormality. There is no third company in the industry. Most of our colleagues use low speed braiding machines.

In terms of quality control, Sunbow insists on incoming material inspection and shipment inspection, and strictly requires quality control of the production process. Each process has a quality control, and never allows parts with abnormal quality to flow to the next process, thereby improving our glass. The quality of the fiber sleeving reduces the scrap rate of the fiberglass sleeving, thereby reducing our manufacturing costs, while most of our colleagues do not.

In terms of price, Sunbow insists on the supremacy of quality and does not fight the price war. Sunbow’s glass fiber sleeves are benchmarked against major international brands such as Mercedes-Benz, Siemens, Toyota, Toshiba, WEG, etc. The prices are moderately high in the industry and cost-effective. The vast majority of our peers are only for temporary performance, the middle and lower reaches of the shootout.

The drive motor of Mercedes-Benz new energy vehicles chooses Sunbow's fiberglass sleeve. I believe that in the near future, new energy vehicles will enter the families of ordinary people, and you don't know that Sunbow has actually entered your life.
