Recently, the Provincial Department of Industry and Information Technology, the Provincial Federation of Enterprises and Industrial Economics released the list of the fourth batch of provincial manufacturing single champion products in 2023. Liancheng Group's special wiper for electric locomotives and carbon fiber hoods for rail transit vehicles won the fourth Batch of Hunan Province manufacturing single champion products.

Special wiper for electric locomotive

Special wiper for electric locomotive is a product of Liancheng Group Electric Technology Company. Electric Technology Company has been deeply engaged in the special wiper system for rail transit vehicles for 20 years. Focusing on the development trend of intelligent and green technologies, Electric Technology Company has devoted itself to the research of relevant core technologies such as product structure, process technology, manufacturing materials, performance test, etc., breaking through key core technologies such as multi-link linkage, multi-axis transmission collaborative optimization, high-torque hydraulic buffer, multi-control mode, intelligent induction wiper, remote control, etc. The special wiper for electric locomotives has high reliability, excellent stability, strong safety, and wide applicability. It has realized the import substitution of core components, solved the "stuck neck" problem, broke the long-term barriers of foreign core technologies, and the overall technology is in the domestic leading The level, the core technology has reached the international advanced level, the domestic market share is in the forefront, and has been exported to more than 20 countries and regions, and has been highly recognized by customers and the market. In 2022, the electric technology company was awarded the national specialized and special new "little giant" enterprise, and its technology center was awarded the provincial technology center.

carbon fiber hood for rail transit

Carbon fiber head cover for rail transit vehicles is independently developed by Liancheng Group Guangyuan Technology Company. The hood adopts carbon fiber composite sandwich structure, the inner and outer layers are carbon fiber composite layers, and the middle sandwich layer is made of PVC foam, which is integrally formed by vacuum introduction. Its safety, comfort, environmental protection, energy saving and other properties are maximized to meet the user experience, and its excellent sound insulation, heat insulation, corrosion resistance, impact resistance and other characteristics meet the European standard fire protection system EN45545HL2 level. Low viscosity, in line with the EN45545HL2-grade high flame retardant carbon fiber hood material system, to fill the domestic carbon fiber hood mass production molding technology short board, to overcome the "stuck neck" technical problems, and to achieve mass industrialization of scientific and technological achievements. Guangyuan Technology Co., Ltd. is a specialized and special new small and medium-sized enterprise in Hunan Province. It has a provincial composite material engineering technology research center, a provincial new material enterprise, and a provincial enterprise technology center. The project molding technology of "Application and Research of Aramid Honeycomb Sandwich Composite Material Structure for Low Cost and High Efficiency Rail Transit" is the first in China, A number of high-tech products with independent intellectual property rights, such as carbon fiber hood, aramid honeycomb interior, represent domestic advanced technology and foreign leading technology.

From the provincial manufacturing single champion product hydraulic shock absorber, special wiper for electric locomotive, carbon fiber hood for rail transit vehicle, to the national manufacturing single champion product electric locomotive special fan, Liancheng Group focuses on the scientific and technological research and development of rail transit equipment components, insists that science and technology is the first productive force, increases R & D investment, and enhances the comprehensive strength of product development, basic research, process technology, testing and testing, etc, with the help of the good development opportunities and superior business environment given by the times, actively integrate into the new development pattern of "building a world-class rail transit equipment industrial cluster", with the traction of the main enterprises in the industrial chain and the support and help of the government and all sectors of society, take customers as the center, meet customer needs, develop high quality products that are recognized and trusted by customers, continue to exceed customer expectations, and enhance customer value.
