In this paper, a method for injection mould of concurrent development was put forward based on graph theory and design structure matrix. In activities identification phase, coupled activity was identified by Boolean operation of adjacent matrix, accessible matrix and strong connected matrix. After re-engineering and optimizing, a structured model is established to open out the principle of the concurrent injection mould design process. The method has the advantage of flexibility to deal with the interrelationship of various tasks, which greatly improved the efficiency of development.
There are many advantages of semi-solid processing technology such as energy saving, high efficiency and net-shaped processing. So it is a promising manufacturing technology in 21 century .It is the premise of getting the non-dendrite semisolid slurry to realize the semisolid processing.This paper reviewed the development of the technique of preparation for semi-solid state slurry and introduced some new researchment about the technique of preparation slurry for semi-solid processing. It researched a new technique of preparation for semi-solid state slurry—cooling by the sine function to produced the semi-solid state slurry. The result showed that the aluminum alloy melt was cooled and controlled nucleation and limited growth in the sine wave The fundamental principles through which sound semi-solid slurry can be effectively obtained were summarized.On the basis of the experiment and simulation,it analysised the temperature field and the flow field of the semisolid 2A12 slurry flow through sine passage. The result showed that there is the cooling and the self-stirring when the semisolid 2A12 slurry flow through sine passage. The fundamental principles through which sound semi-solid slurry can be effectively obtained were summarized. Finally, we presented a patent this simple process .
