Analysis on the most popular die casting hardware

  • Detail

Analysis: China's die-casting hardware industry has ushered in a diversified leap forward development. The diversity of the application field of die-casting products is one of the characteristics of China's die-casting production. The proportion of automobile die castings in Japan and the United States is as high as%, while that in China is only about 50%. Coupled with the balance of 17million motorcycles, 2.68 million agricultural vehicles and 8million electric bicycles, the impact of fluctuations in the automotive market on the die casting market has been greatly reduced. Moreover, in 2005, the automobile production and sales still maintained a growth rate of more than 12%, and the hardware lamps, household appliances, electric tools and other industries were very prosperous. Therefore, the development of China's die-casting production can still maintain a stable and high growth rate

2005 industrial demand and proportion of main users of die castings: 542700 tons of automobiles and motorcycles, accounting for 62.8%; 138200 tons of hardware toy car models, accounting for 16.0%; 101900 tons of electrical and electronic computers, accounting for 11.8%; 81400 tons in general machinery and other fields, accounting for 9.4%

die casting of aluminum alloy cylinder block of automobile engine

in recent years, die casting of aluminum alloy cylinder block of automobile engine has developed rapidly in China.
