In recent years, multinational auto giants have set off a new round of engine investment in China. In April, Changan Automobile Group, Ford Motor Company and Mazda Motor Company established a new engine plant in Jiangning, Jiangsu. At the beginning of May, FAW-Volkswagen Engine (Dalian) Co., Ltd. was established with an annual output of 300,000 engines. On May 25, Shanghai Automotive Co., Ltd. announced a joint venture with Volkswagen AG in Shanghai to establish Shanghai Volkswagen Powertrain Co., Ltd., which will produce 300,000 engines per year. In June, the new engine plant of SAIC-GM-Wuling Company laid a foundation in Liuzhou, with a total investment of 3.2 billion baht and an annual output of 500,000 engines. The rapid development of investment in automobile engines will strongly promote the accelerated development of aluminum alloy engine block casting.

There are nearly 100 domestic aluminum alloy wheel hubs for automobile and motorcycle aluminum alloy wheels and pistons, mainly low pressure, gravity, and squeeze casting, and less die casting. In 2003, the total output was 42.5 million; in 2004 it reached 47 million, an increase of 10.6% year-on-year, of which exports were 17 million, accounting for 36.17%. More than 52 million in 2005. Its main enterprises are: Qinhuangdao Daica Wheels Company, Nanhai Zhongnan Aluminum Alloy Wheel Company, Zhejiang Wanfeng Aowei Steam Turbine Company, Zhejiang Wanfeng Motorcycle Company, Baoding Lizhong Wheel Company, Kunshan Liufeng Machinery Industry Company, and Sanmenxia Jiashi Aluminum. Alloy Wheel Company, Taian Huatai Aluminum Wheel Company, Jiangmen Huatai Aluminum Wheel Company, Chengdu Yuanda Wheel Company, Xiamen Minxing Industry Co., Ltd., Shanghai Guoxing Metal Product Company, Fushun Shunhua Aluminum Wheel Company, Shanghai Jinheli Wheel Company, Kunshan Yuanqing Aluminum Company, Shenyang Durui Wheel Company, Zhejiang Tailong Aluminum Wheel Company, Zhejiang Yuhuan Hengbao Wheel Company, Zhejiang Zhengtai Aluminum Wheel Company, Dongfeng Huatai Aluminum Wheel Company, Danyang Jincheng Wheel Company, Shandong Binzhou Bohai Aluminum Wheel Company , Weihai Wanfeng Aowei Turbine Company, Shanghai Wanfeng Aluminum Company, Chongqing Wanfeng Xinrui Wheel Company, Chongqing Jieli Wheel Company, Ningbo Orwell Wheel Company, Chongqing Zhongnan Aluminum Alloy Wheel Company, Lijin Technology Group increased The investment in the field of aluminum alloy wheels is in the ascendant.

The diversification of die-casting products is one of the characteristics of die-casting production in China. Japan and the United States accounted for 80-90% of the total die castings, while Chinese auto die castings accounted for only about 50%. Together with the balance of 17 million motorcycles, 2.68 million agricultural vehicles and 8 million electric bicycles, the impact of the automotive market fluctuations on the die casting market has been greatly reduced. Moreover, in 2005, the production and sales of automobiles still maintained a growth rate of more than 12%. Hardware, lighting, home appliances, and power tools were very prosperous. Therefore, the development of China's die-casting production still maintained a stable and high growth rate.

In 2005, the demand and proportion of major users of die-casting industries were: 542,700 tons of automobiles and motorcycles, accounting for 62.8%; 138,200 tons of hardware toy cars, accounting for 16.0%; 10,1900 tons of electrical and electronic computers, accounting for 11.8%; 81,400 tons of general machinery and other fields. Accounted for 9.4%.

Die casting of automobile engine aluminum alloy cylinder In recent years, China's automobile aluminum alloy engine die casting has developed rapidly. According to Luo Baihui, Secretary-General of the International Model Association, Guangzhou Dongfeng Honda Engine Co., Ltd. took the lead in introducing a large number of die-casting car aluminum alloy cylinders. Subsequently, Chongqing Changan Automobile Group, Changan Suzuki Automobile Company, and Harbin Dongan Automobile Power Company all introduced automatic production lines around the year 2002 to die-cast aluminum alloy cylinder blocks for automotive engines. Shanghai Qiantong Auto Accessories Co., Ltd. produced Liuhe Wuling Automotive Aluminum Alloy cylinders, and later introduced 3,550 tons of fully automatic die-casting production lines, dedicated to the development and production of larger aluminum alloy die castings. Changchun FAW Group introduced 2700 tons of fully automatic die-casting production lines and Yixing Jiang Xu Foundry Company introduced 3,200 tons of fully automatic die-casting production lines. In September 2004, Guangdong Hongtu Science and Technology Co., Ltd. 3,000 tons automatic die-casting machine production line was formally put into production, both for the development and production of large-scale aluminum, Magnesium die castings create conditions.
