In the 2008-2009 annual award-winning scientific papers of China National Heavy Duty Truck Group Science and Technology Co., Ltd., there were 14 papers won by the Department of Component Manufacturing: 1 first prize, 2 second prizes, 7 third prizes and 4 encouragement prizes, among which The "wheel structure optimization" co-written by Hao Xiaoxia, Huo Yanli, and Yu Fei won the first prize, and Li Hui wrote "The problem of the EGR cooler shell shrinkage hole" won the second prize...... Since its inception, China National Heavy Duty Truck Parts Manufacturing Department has unswervingly adhered to the scientific concept of development. The leaders of the parts manufacturing department have attached great importance to technical work, and have been active in the products with high failure rate after sales, production management, and problems in the quality control process of A7 products. Organize enterprise technical personnel to carry out technological research, technological innovation, and quality improvement activities, and encourage them to be good at summing up work experience, recording various data in process improvement, forming text, and facilitating guidance and communication. From 2008 to 2009, the technical personnel of CNHTC Component Manufacturing Division improved the V-shaped thrust rod, balance shaft, intermediate transmission shaft support assembly, new saddle, engine support, leaf spring pressure plate, EGR cooler shell and other products. The product quality has been greatly improved. Compared with the same period of last year, the claim for the reduction of RMB 1.1075 million in the period from January to July 2009 was reduced, and through the application of new technology, the EGR cooler shell rejection rate was reduced by 7 to 8%.
