Only 5% of foundries in China have reached the level of foundries in developed countries in Europe and America. Casting quality stability, consistency and traceability are poor. The distribution of casting products is unreasonable, and the proportion of high value-added and high-tech products is low. Low production efficiency and high energy consumption. Little contribution to world casting development and progress. Casting prices and production values are low. The wages of foundry workers are low. The technical standard value is slow and backward. Labor safety and the environment are poor. Countermeasures: The report elaborated on the direction of efforts from government departments, universities, research institutions, associations and associations, and enterprises. Looking forward to understanding the development trend of the international foundry industry, seize the opportunity to further develop and improve the level of China's foundry industry. Precision casting

The high level of China's foundry production technology and good equipment are limited to a few key enterprises, and the overall technical level of the industry is backward. The specific performance is that the mold is still processed by hand or simple machine; the socialization, specialization and commercialization of the production and supply of raw and auxiliary materials for casting are far from the needs of the development of new technology and new technology in terms of variety quality; The design relies on personal experience, computer control and auxiliary technology cae technology application is less; casting technology and equipment and other basic conditions are poor; the production process has a high proportion of manual operation, and the on-site workers have low technical quality; only a few large-scale automobile and internal combustion engine group foundries adopt advanced modeling. Most of the foundry companies still use shock compression molding machines or even manual molding. Low-pressure casting can only produce non-ferrous parts; the production of stable production by epc technology is limited to castings such as exhaust pipes and casings, and the productivity is low, and the dimensional accuracy and surface roughness of castings are low; although a complete casting industry standard has been established. System, but most companies passively enforce standards, and some companies have a scrap rate of more than 30%.
