Current situation of mechanical casting industry

Today, with the rapid development of science and technology, due to the special advantages of casting process, there is no other manufacturing process to replace some complex structural parts. The casting process is still the most economical and convenient metal forming process. With the global economic integration and the increasingly close international cooperation and fierce competition, China's automobile foundry industry should give full play to the advantages of foundry resources and develop its own foundry industry.

1. Current situation of China's foundry industry
China is the largest casting production country in the world today. According to data, the output value of China's casting products accounts for about 1% of the national economy. In recent years, the import and export trade of castings has increased rapidly, and the output of castings has reached about 9%. There are more than 20000 foundries in China and 1.2 million employees in the foundry industry. The production of castings in the "Yangtze River Delta" region accounts for 1/3 of the country's total. The region is mainly dominated by private enterprises. The development of the automobile and auto parts industry has strongly promoted the development of the casting industry. Wanfeng Auto is the largest aluminum alloy wheel enterprise in Asia, with an annual output value of more than 1 billion yuan and an export value of 6000 dollars. Kunshan Fujiwa Machinery Co., Ltd. produces castings for automobile engines and brake systems, with an annual output of 40000 tons and sales revenue of 550 million yuan. East China Texel is an advanced modern cylinder block casting manufacturer with an annual output of 1 million pieces
Car cylinder block casting capacity. Shanxi is a province with large casting resources. It is rich in pig iron, coal, aluminum and magnesium, electricity, and labor resources, giving Shanxi's casting industry unique advantages. It has 500 casting enterprises, 80% of which are private enterprises. The annual output of Shanxi International, Hejin Shanlian and Shanxi Huaxiang reached 40000 t, 20000 t and 120000 t respectively. In the "three eastern provinces", FAW Group, Hafei Group and other key automobile enterprises have driven the growth of automobile casting production. FAW Group Casting Company has formed a production capacity of 400000 tons of castings. Liaoning North Crankshaft Co., Ltd. will form a crankshaft production base with an annual output of 150000 engines, 1 million crankshafts and an output value of 2 billion by the end of the "11th Five-Year Plan". The die casting industry in the "the Pearl River Delta" is developed, with more than 700 die casting enterprises and an annual output of 200000 tons. Dongfeng Nissan, Guangzhou Honda, Guangzhou Toyota and other parts enterprises have strongly driven the development of the die-casting industry. The production of die-casting parts for car cylinder block and cylinder head has increased year by year.
