Both water mist and air mist have advantages and disadvantages in preparing metal powders, and their physical properties are different, especially their shapes are different. It will be the development direction of water mist powder preparation in the future to combine the two to form air water combined atomization. The principle of atomization is analyzed, and it is pointed out that nozzle design and atomization mechanism are the core of atomization technology. However, the spray-through process of automatic casting machine is a very complex physical and chemical process of casting materials, and its development is mainly due to the lack of theoretical guidance. Nozzle design lack of transparency, unified statistical standards, poor continuity of equipment update, high research and development costs, resulting in nozzle development lag behind the development of metal powder production industry. But there are still some unsolved technical problems that require expert help. The company mainly leads the research and development of intelligent lighting system, set up the technology development department, responsible for the company's production, technology management and new product development, 16 technical developers. The intelligent lighting system adopts the high-frequency doppler effect principle, micro testing LED intelligent control technology, controlled by single chip microcomputer, using software to eliminate circuit noise, is implemented to determine, sleep in the daytime, awakened state of the automatic control, solve the stairs lighting in public places, large power consumption, low efficiency, the interference of noise and vibration are especially vulnerable to the outside world, cause energy waste and environmental pollution, shorten technology ask casting aluminium, energy saving can reach more than 80%.
