Abstract: Based on numerical calculations and an artificial neural network (ANN) model as well as intelligent control technology, a set of intelligent control simulation system was founded for the injection process of standard tensile samples. The results show that this system can automatically optimize injection parameters according to the requirement of injection bodies to the properties (such as density distribution). It is found, after the introduction of the intelligent control simulation system to injection processing, that the uniformity of density distribution in injection bodies is obviously improved and can meet the expected density distribution, proving that this intelligent control simulation system is feasible.
