Notes:
The filling process of plastic precise gear is simulated by CAE software and the factors thatinfluence injection molding accuracy in single cavity mold are discussed in this paper. With theassistant of visualization technology, the mechanism of filling unbalance which influences efficientinjection molding was especially studied. The model of filling unbalance was supposed that wasverified experimentally by visualization technique. It is clarified that the mechanism of fillingunbalance results from dissymmetrical temperature distribution on the cross-section of runner, whichis strongly influenced by the shear heat and the cooling process in the runner. At the same time, a newmethod was proposed for improving the filling imbalance by applying appropriate injection moldingprocess without any changes in runner shape of multi-cavity mold
