Only 5% of foundries in China have reached the level of foundries in developed countries in Europe and the United States. Poor quality stability, consistency and traceability of castings. 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 the development and progress of the world foundry. Casting prices and output value are low. The wages of foundry workers are low.
The formulation of technical standard values is slow and backward. Labor safety and environment are poor. Countermeasures taken: The report expounds the direction of efforts from government departments, universities, research institutions, societies and associations, and enterprises. Looking forward to understanding the development trend of the international foundry industry and grasping the opportunity to further develop and improve the level of my country’s foundry industry.
However, my country’s foundry production technology level is high and the equipment is well-equipped only in 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 machinery; the socialization, specialization, and commercialization of the production and supply of casting raw and auxiliary materials are far from being socialized, professional, and commercialized, and the variety and quality are far from meeting the needs of the development of new technologies;
The design is mostly based on personal experience, and the application of computer control and auxiliary process cae technology is less; the basic conditions such as casting technology and equipment are poor; the proportion of manual operation in the production process is high, and the technical quality of on-site workers is low; only a few large automobile and internal combustion engine group foundries use advanced modeling For the core-making process, most foundry companies still use shock-compression molding machines or even manual molding. Low-pressure casting can only produce non-ferrous parts; the stable production of 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 relatively complete casting industry standard has been established System, but most enterprises passively implement the standard, and some enterprises have a rejection rate of more than 30%.
