Casting process is the earliest metal forming method. About 20% of automobile parts need to be produced by different casting processes. Automobile castings are mostly used in the power system or key structures of automobiles. At this stage, the production technology of automobile castings in countries with relatively developed industries is advanced. Both the production process and the quality of castings have high standards. At the same time, there will be no more pollutants in the production process, and the negative impact on the construction of the surrounding environment is small.
At present, the raw materials used in the production of automobile castings have formed a standardized system, and the production process has also achieved mechanization, automation and intelligence. The industrialized countries will use information technology to improve the casting process level, and the overall casting scrap rate is low. In addition, some countries have established transnational service systems using network technology to strengthen the development of the casting market. In contrast, although the total production of automobile castings in China is relatively high, the quality of products has a large room for improvement. The overall technical quality of castings is relatively low, and there is still a certain gap between the simple casting structure and the developed countries.
The quality and performance of automobile castings are directly related to the production of vehicles. In the face of various requirements of automobile manufacturing, casting manufacturers and technicians need to clarify the problems in the production process of castings, and use modern casting technology to realize the integration, lightweight and digitalization of automobile castings, and realize the research and development and production of automobile castings through high-performance casting materials, automated production equipment and other means, It is necessary to carry out research, development and application for the existing production process, and reasonably select manufacturing technology according to the specific requirements of casting production, so as to improve the production level of automobile castings, reduce production costs, optimize the overall quality of automobile quality, and improve the economic and ecological benefits of automobile production.
