Abstract: In view of the complexity present in the process of the design and control of the gas-assisted injection, a response surface model was formulated based on orthogonal experimental design and response surface design combined with correlative significance test. The melt temperature, delay time, air pressure, and time were determined as the highly significant factors. The mesh adaptive search algorithm was applied to optimize the model and a satisfactory solution was found rapidly and exactly. At last, a case study was carried out which demonstrated the method was effective in numerical simulation and the simulation result was in accord with the optimal ones.
