Determination the parameters of injection moulding by method of process virtual modeling

Article is devoted to research the process of filling the compression mold with short fibers polymeric composite material. In details the new process of injection molding, relating to molding under pressure, in which the new equipment and new material are used is considered. For determination the parameters of injection molding the method of virtual modeling of process in Autodesk Simulation Moldflow Insight CAE system is used. The main integrated characteristic of injection molding process is the orientation tensor of material internal fibers. For optimization the orientation tensor the comparative analysis of statistical methods of estimation the quality for multiple-factor technological process was carried out. As a result Tagutti's method showed the greatest accuracy of the forecast. Further it is necessary to develop algorithm for optimization the molding process on the basis of orientation tensor.
