　　Driven by the sustained and high-speed development of the national economy, the total output of die casting in 2006 was 1024 000 tons, including 802140 tons of aluminum die casting, 202 400 tons of zinc die casting, 13620 tons of magnesium die casting and 5840 tons of copper die casting, but this is only a narrow sense of high-pressure die casting. According to the broad sense of die casting category, including low pressure casting and squeeze casting and other pressure casting molding process, its total output is about 1.5 million tons. The continuous development of die casting industry has promoted the rapid development of the mould industry. During the Tenth Five-Year Plan period, the average annual growth rate of mold production in China was as high as 18%, and now a mold industry cluster with an annual output value of 70 billion yuan has been formed all over the country.During the "fifteen" period, domestic commodity molds meet 80% of the total market demand. In 2005, for example, imports of moulds accounted for 2 billion 68 million US dollars, accounting for 20% of the total demand of the mold market. In 2007, China's GDP growth target was set at 8%. China's die casting and die market will continue to expand.1 the inevitability of continuous development of die casting and die industry in China1.1 the sustained development of national economy is the fundamental guarantee for the growth of die casting and mold production.China's poverty and backwardness in the past hundred years contain tremendous energy to turn over. Under the guidance of the reform and opening up policy, this "advantage of backwardness" has become a driving force to promote social and economic development. In China, a new round of consumption structure upgrading based on "living and banking" has started. According to the requirements of a well-off society in an all-round way, the automobile ownership of 100 urban residents will be about 40%, and the automobile ownership will reach 120 million vehicles by then, plus the renewal of at least 150 million vehicles. According to this goal, the automobile industry will have to continue to develop for more than 20 years; by 2020, the urbanization rate will reach 60%, the urban population will increase by 300 million, and about 10 billion square meters of housing will be needed. In addition, the per capita housing of 560 million urban residents has increased from 25 square metres to 35 square metres, and about 5.6 billion square metres of additional housing are needed. Both of them need 15.6 billion square metres of new housing, at least 15 years from the present construction speed. Therefore, China's "car fever", "real estate fever" and even "economic fever" will continue, especially the high-speed development of manufacturing industry will continue longer. The 11th Five-Year plan GDP grew by an average of 7.5% per year. The progress of the society and the will of the people determine the trend of the market, which provides the most fundamental guarantee for the continuous development of die casting and mold industry in China.1.2 world economic integration has pushed the focus of die casting production to China.In the tide of economic globalization, the international division of labor in the industrial development sequence is taking shape. China's economic level, especially its tens of millions of tons of non-ferrous metal resources, abundant labor resources and huge market, determines that China is mainly in the product manufacturing sequence in the international industrial division of labor. As a result, the production and manufacturing tasks of international nonferrous metal castings and their products will be undertaken for a long time. It has become an inevitable trend to shift the focus of world nonferrous metal casting production to China.1.3 the rapid development and lightweight of the automobile industry will promote the sustained development of die casting and mould market.Lightening of casting has become an important development trend. For example, a new generation of cars aims to reduce fuel consumption to three liters per 100 kilometers, which requires a significant reduction in vehicle weight. The urgent need of vehicle lightweight provides broad prospects for the development of die casting and die industry.The huge demand for die casting and mold in domestic and foreign markets determines that the continuous development of die casting and mold industry in China is a historical necessity.2 diversified development of die casting and die industry in ChinaChina's automotive industry is growing by 27.6% a year with a high-speed and sustainable development, coupled with the balance of 21 million motorcycles, 2.5 million agricultural vehicles and 10 million electric bicycles; hardware and lanterns, electronic appliances, electric tools and other industries are very prosperous, so the development of China's die casting and mold industry has maintained a greater stability and a higher growth rate. .2.1 automotive engine aluminum alloy cylinder body die castingIn recent years, die casting of automobile aluminum alloy engine block has been developing rapidly in China. Guangzhou Dongfeng Honda Engine Co., Ltd., Chongqing Chang'an Automobile Group, Chang'an Suzuki Automobile Co., Harbin Dongan Power Co., Ltd. all introduced fully automatic production lines around 2002 to die-cast aluminum alloy cylinder block of automobile engine. Shanghai Qiantong Automobile Accessories Co., Ltd. produces aluminum alloy cylinder block of Liuhe Wuling Automobile, and then introduces 3550 tons automatic die casting production line to devote itself to the development and production of larger aluminum alloy die castings. Recently, Changchun FAW Group, Yixing Jiangxu Foundry Co., Ltd., Guangdong Hongtu Technology Co., Ltd. and Xuhang Die Casting Co., Ltd. have introduced large-scale automatic die casting machine production lines to develop large-scale aluminum alloy die castings such as automobile cylinder block.Especially since 2005, the multinational automobile giants have set off a new round of engine investment in China, which is becoming more and more vigorous. This will effectively promote the accelerated development of aluminum alloy engine cylinder block die casting, and put forward greater demand and higher requirements for large-scale precision mold and high-quality mold steel.
