| Abstract: | This paper is concerned with the practical application of closed_loop control on the gas pressure during the gas_assisted injection molding process.One of the critical factors for the successful application of the process is the obtaining and maintaining of a desired gas injection pressure.In this paper,the model of pressure control system is derived theoretically and simulation is carried out by means of Simulink of the toolbox of Matlab.The results can be useful for study and design of a closed_loop pressure control system. |
