Improvement of casting technology and quality: China since the reform and opening up, the foundry industry foundry development has been a very big change, including the level of technology, quality, service and so on. China's casting quality has improved significantly. Mainly in the casting production process in the production of scrap compared to the previous drop a lot; and then is a variety of casting accuracy (geometric accuracy, dimensional accuracy), surface roughness ra, mechanical properties, etc. reached the international level. Foundry enterprises already have the ability to display their castings in our country and foreign exhibitions, and obtain a high degree of recognition. In addition, China's casting technology has greatly improved, has been able to match the developed regions abroad. Since the reform and opening up, the original many enterprises using sand casting process, and now has begun to CNC, automation, intelligence, mechanization of the direction of advancement. The original traditional manual sand casting occupies most of the situation is slowly disappearing. Many of the foundry enterprises have begun to use intelligent machines induction furnace and cupola, induction furnace duplex process. These kinds of advanced equipment, technology, technology means that our country has the ability to manufacture and produce better quality, higher precision castings. At present, China's production of ductile iron machine tools about 146 tons; cast steel for more than 520 tons, China now has more than 100 companies can have the ability to produce a single piece weighing 30 tons and more castings. China's foundry industry has undergone radical changes. Emerged a large number of high technology, good quality casting enterprises.
Castings import and export volume: we according to the customs import and export data in the casting of goods statistics, in 2014, a year, China's exports of all kinds of castings for 2 million tons, while in 2013, China's exports of all kinds of castings 1.78 million tons. Year-on-year growth of 12%; in 2014, China's castings export trade totaled 3.1 billion U.S. dollars. 2013, China's castings exports totaled 2.9 billion U.S. dollars. The total value of China's castings export trade in 2013 was 2.9 billion dollars, an increase of 6.0%. The following table will give 2005 to 2007 China's casting production and export situation table. And the figures are only pure casting exports, not including the amount of castings in the processing, assembly. China's automobile parts (including castings) of the export situation is very encouraging, according to statistics, China's average annual growth rate of about 70%. Imports of castings accounted for the number of castings exported less than 1.7%, a very small number of castings due to technical problems such as the need to import. For example, high-temperature blades of aircraft engines and nuclear power equipment in some of the castings. There are some need to import castings such as large hydropower equipment runner castings. Some castings can now be manufactured in China, do not need to rely on imports.
The main problems of China's foundry industry: China's foundry industry, although the current development trend is very good, but compared with developed regions we still have a big gap. Domestic technical level, technology and means of comparison with them there is still a certain gap. This gap leads to the export volume of our products is small, the economic development will have certain obstacles. In addition, the modern industry, technology backwardness, equipment, energy consumption and high consumption of raw materials and environmental pollution and workers work in a poor environment and other issues will seriously affect the development of the foundry industry, affecting the regional economy.
Prospects for the development of the foundry industry: China is a foundry country, China's transformation into a foundry power must overcome the resources, energy, talent and environmental issues, the pursuit of quality, environmental protection and other directions. Therefore, we must use high and new technology to improve the quality of castings, change the Chinese castings in the international market, the technical content is not high, the situation of low prices. At present, China's casting industry is facing a good opportunity for development. First, the rapid development of our country's economy so that all areas of our country have entered a state of rapid development; and then is the economic globalization of the foundry industry in various regions have developed a very mature, driving our country into the globalization. China's accession to the World Trade Organization, will benefit greatly from it, learned advanced science and technology, management methods. These opportunities for China's foundry industry to realize the casting of large countries to casting the transformation of a strong country provides an excellent opportunity. Foundry industry will also develop in the following direction.
