aluminium pressure die casting components.Future development direction of aluminum alloy die casting industry

　　1. To scale up

　　With the prosperity of the market economy, the development of new products has a rapid momentum. In order to meet the needs of large structural parts, whether it is die casting machine or die casting mold, it is imperative to develop in the direction of large scale.

　　2. Improve the automation level of die casting production

　　The current situation of die casting production is that the die casting efficiency is not high and the waste of human resources restricts the development of die casting production. For example, in the cold chamber die casting machine aluminum alloy die casting, the degree of automation of the injection of metal liquid and the removal of die casting parts is not high. In these links of die casting production, only by improving the degree of automation can we meet the needs of future development trends.

　　3. Gradually improve and improve the level of die casting technology

　　The die casting process is an intricate work. In addition to theoretical research, it also needs to be explored and accumulated through practice in order to gradually improve. However, from the current situation, there are still some problems that need to be improved, such as how to reduce and eliminate the involvement of gas when the metal liquid fills the cavity, produce a die casting without porosity, how to improve the process conditions, eliminate the shrinkage hole, cold insulation, cracks and other die casting defects, and improve the comprehensive mechanical properties of die casting.

　　At present, there are practices in this regard, such as the use of vacuum die casting to eliminate the gas in the cavity in advance, and the new technology of ultra-high-speed die casting to make the porosity fine, have obtained satisfactory results.
