In the future, the development direction of the aluminum alloy die -casting industry.die casting for led housing

　　1. Development to largeization

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

　　2. Improve the level of automation of die casting production

　　At present, the status of die -casting production is that the lack of die -casting efficiency and the waste of human resources restrict the development of die casting production. For example, on the aluminum alloy die casting of the cold chamber, the automation of the injecting of metal liquid and the removal of the die -casting is not high. In these links of die casting, 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

　　Die -casting process is an intricate job. In addition to theoretical research, it is also necessary to gradually improve through practical exploration and accumulation. However, from the status quo, there are still some problems that need to be perfected, such as how to reduce and eliminate the involved in gas when filling the cavity of the metal solution, how to improve the process conditions of the air -free die, how to improve the process conditions, eliminate the die castings, eliminate the die -casting parts, and eliminate the die castings. Cast casting defects such as shrinking holes, cold partitions, and cracks improve the comprehensive mechanical properties of die castings.
