custom aluminum profiles.The development trend of alloy die casting industry

　　1. Like large-scale development

　　With the prosperity of the market economy, the momentum of new product development is rapid, in order to meet the needs of large structural parts, whether it is die casting machine or die casting mold, like the trend of large-scale development is imperative.

　　2. Improve the automation level of die casting production

　　At present, the situation of die casting production is not high die casting efficiency and waste of human resources restrict the development of die casting production, for example, in the cold press chamber die casting machine, the injection ratio of metal liquid and die casting parts take out the degree of automation is not high, in the die casting production link, only improve the degree of automation, in order to meet the needs of large development forms.

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

　　Die casting process is a complicated work, in addition to theoretical research, but also need to go through time to explore and accumulate 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 is filled into the cavity, resulting in a die casting without porosity, how to improve the conditions of the die casting process, eliminate the shrinkage of the die casting, cold songs, cracks and other die casting defects, and improve the comprehensive mechanical properties of the die casting.

　　At present, there have been practices in this area, such as the use of vacuum die casting to improve the elimination of gas in the cavity, and ultra-high-speed die casting, so that the porosity of the new technology, have obtained ideal results.
