The American “modem casting” magazine publishes the statistics of casting output of countries (regions) all over the world every year. At present, countries all over the world regard the total casting output of countries (regions) published by “modem casting” as “the total casting output of the world”. Although the output of some countries is not included, it has little impact. Among the countries participating in the casting output statistics of “modern casting”, Russia is an important casting production country. However, Russia does not submit statistics every year, so it is difficult to analyze its casting production. In addition to Russia, the 10 countries with the highest casting output in recent years are China, Japan, Germany, India, France, Italy, South Korea, Brazil and Mexico. These 10 countries are the main casting producers at present, including industrial developed countries and developing countries. The analysis of the trend of casting output in these countries in recent years can enable us to understand the development of the world casting industry:
1.In industrialized countries, the total output of castings in the past 10 years can be considered as stable, and the two economic powers, the United States and Japan, have shown a steady downward trend in recent 5 years. However, it can not be considered that thein industrial developed countries has begun to move towards “depression”. In fact, the development of their foundry industry has entered a new stage.
(1) the manufacturing industry in industrialized countries has reached a high level, and the facilities needed by people’s life have been basically complete. Therefore, the demand for castings has slowed down, and the per capita consumption of castings is much more than that in developing countries;
(2) in the total output of castings, the share of steel and iron castings decreases and the share of light alloy castings increases. Therefore, even if the output (weight) of castings decreases, there are a lot of castings;
(3) in the context of market globalization, castings with low technical content are imported from developing countries, and castings with high technical content are produced by themselves. In addition to their own use, they are also exported to developing countries;
(4) Increasing investment in environmental protection and improving working conditions;
(5) committed to the development of new products and technologies.
2.The output of castings in developing countries has been increasing in recent years. In the past, the economic foundation of developing countries was weak, the level of manufacturing industry was very low, and the people’s living facilities were poor. In order to develop the national economy, it is necessary to increase the demand for Castings in all aspects. Among them, in the past five years, China’s national economy has increased at a large rate, and the output of castings has also increased significantly. However, it should be noted that so far, the per capita casting consumption in developing countries is still far lower than that in industrial developed countries, which shows that there is still a lot of room for the development of the casting industry in developing countries.
According to the number of foundry production enterprises in various countries and the output of various castings in various countries published by modem casting magazine.
1.In most industrial developed countries, the number of nonferrous alloy foundries accounts for more than half of the total number of foundries; A few developing countries also have such characteristics. This shows that the production of non-ferrous alloy castings, especially light alloy castings, has developed rapidly in recent years.
2.The average annual output of each foundry in most developing countries is low, which shows that it is very urgent to realize economic scale operation and improve production facilities.
