Precision casting products development trend is the requirement of castings have better comprehensive performance, higher precision, less allowance and more bright and clean surface.In addition, the requirements of energy saving and the call for society to restore the natural environment is becoming more and more high.In order to meet these requirements, a new casting alloy will be development, smelting new technology and new equipment will appear accordingly.Precision casting production mechanization automation at the same time of constantly improve, will be more the flexible production direction, to expand its adaptability to different production batch and many varieties.To save energy and raw materials will get the priority to the development of new technology, have little or no polluting new process equipment will be the first to be taken seriously.Quality control technology in the process of testing and nondestructive flaw detection, determination of stress, there will be a new development.
