Opportunities challenges for China's precision castings

China's precision casting industry has entered a stage of rapid development since the early 1990s. After more than ten years of vigorous development, it has become a large-scale production in East Asia, In the 11th Five Year Plan of China, it is clearly put forward that the energy consumption of enterprises in China's GDP will be reduced by 20% the total output of key environmental pollution will be reduced by 10%. It is a major measure to carry out the construction of ecological civilization build a socialist society to build a harmonious society; it is a necessary choice for the development of a conservation oriented society a green environmental friendly society; it is an inevitable choice for promoting the adjustment, change improvement of the industrial structure of economic development; it is a necessary provision for safeguarding the overall interests of Chinese culture, The national development Reform Commission has also formulated a medium long-term overall plan for environmental protection energy conservation, which means that the state will carry out compulsory inspection on various manufacturing industries, outdated high-energy technical processing technologies will be eliminated.

Lost foam casting is one of the most energy consuming manufacturing industries in social economy, accounting for 25-30% of the total energy consumption of machinery in China. Therefore, as the precision casting of advanced technology in the mechanical processing industry, we must take the development concept of scientific research as the guideline, solve the rough crazy lean production mode, seek quality, benefit, protect the ecological environment, take the people as the basis. In order to achieve this goal, people need to pay attention to reduce the demand of raw materials save energy all the production processes of precision casting. Shell making process is a very important part of precision casting, which immediately endangers every stage of post-processing process. Therefore, it has become a top priority to find a kind of shell making process that is energy-saving, environmental friendly, high quality low price. The zf-801 quick drying silica sol developed designed by Wuhan Zhifa Technology Development Co., Ltd. is developed based on this point.
