With the trend of lightweight automotive products, the continuous improvement of component precision, performance and quality requirements will inevitably give the automotive industry a broader and higher connotation. For more than 40 years, China's automobile industry has found its own production from scratch. From small to large, processes and equipment and production management have undergone major changes. The full introduction of the former Soviet Union’s automobile manufacturing process and equipment, and the establishment of China’s first automobile production base—a first automobile manufacturing plant; by the end of the 1960s, self-reliance and the establishment of a second automobile manufacturing plant in a “jubao†manner; up to the present The formation of a modern car production base has made the foundry production of the automotive industry in China continuous and substantial. From the shock jar style of the 1950s to the high pressure modeling of the 1960s, the application of airflow impact modeling techniques in the 1980s.
The core-making process has evolved from the oil sand core in the early years of the founding of the People's Republic of China to the hot box and shell core, until the current cold box core making process. In addition, large-scale hot blast dust cupola furnaces, large-scale industrial frequency insulation furnaces, casting and sand-falling cleaning automation equipment, and large-scale and highly efficient automated sand processing equipment have all been developed and applied. In short, new art, new materials, new equipment and new technologies. The continuous adoption, especially the application of robots, electronic computers and advanced detection and control methods, has brought new situations and higher economic benefits to the large-scale professional casting production of China's automobile industry. Development of Foundry Production and Technology in the Automotive Industry. The Foundry Production of Automobile Parts Since the founding of the People's Republic of China, the casting production of China's automobile industry has developed rapidly. Especially in the early 1950s, the increase in demand for auto parts has promoted the development of auto parts production. Guiyang Automobile Repair Factory, established in 1952, centrifugally casts babbitt bearing bushes by hand and uses centrifugal casting of hot forged billets to produce flanging bushes. By 1956, the annual output had reached more than 600,000 pieces.
