Gears and clutches are key basic components in the field of mechanical transmission, and they belong to industries encouraged and supported by the state. The company's products include gears and clutches, which have strong industry competitiveness in the field of friction materials, the core components of high-precision gears and clutches. For gears, the company's technical team can adopt the traditional "hobbing+shaving" production process to ensure that the precision of gears produced in batches reaches ISO or DIN6-7. Through the "hobbing+grinding" process, the product accuracy can reach ISO or DIN4 level, thus meeting the differential requirements of different customers for gear accuracy. As for friction materials, the company has been deeply involved in paper-based friction materials for many years, which consists of seven parts: non-metallic paper-based wet friction materials (GB_T37208-20 18) and wet automatic transmission friction element test methods (GB_T35472-20 17)(**). The company participated in four parts. As one of the few enterprises in the industry with two core technologies and production advantages of paper-based friction materials and high-precision gears, the company has developed into an excellent enterprise in the field of transmission parts segmentation with its continuous technological innovation ability and lean quality management system, and has now entered the supply chain system of world-class enterprises. The company has always adhered to the high-quality market route, with customers including Honda, Yamaha, Fuji Syusuke, TEAM, piaggio, Voith and other large multinational companies, and has long been a first-class supporting enterprise for these customers. In the cooperation with the above-mentioned well-known enterprises, the company's products and comprehensive service capabilities have been widely recognized by customers, and were awarded "Best Supplier" by piaggio in 20 14, "Excellent Supplier" by Ma Yang and Sundiro Honda in 20 19 and 20021year respectively, and won "Excellent Supplier" by Wuyang Honda and Construction Yamaha for many times. The company attaches great importance to R&D innovation and has established a perfect internal R&D system. As of the signing date of this prospectus, the company has obtained 39 authorized patents, including 8 invention patents. The company produces "100CC- 150CC motorcycle paper-based clutch assembly", "AVT gearbox gear", 100CC- 150CC series gear assembly of CWC motorcycle clutch assembly "and" " Kloc-0/11-4D20-000-00/200 In addition, the company won the first prize of scientific and technological progress in Chongqing, a specialized and innovative enterprise in Chongqing, an outstanding private enterprise in Chongqing, an enterprise technology center in Chongqing and a demonstration enterprise in technological innovation in Chongqing.
