An investigation was made theoretically and experimentally on the pressure variation in rubber injection moulding. The pressure and energy control equations in the filling flowmodel were as follows. TheGaussian method was used to solve the general finite element equation. It was showed through thecomparative analysis that the results obtained with the selected mathematical model and calculation method were approximate to the measured ones. The proposed model could be used instead ofa large number of tests to simulate the rubber filling process. The resultant values were treatedwith Grapher software. The influence of various factors on the filling process was expressed directly by figures and tables.
