Most reciprocating screw injection molding machines are equipped with a back-flow valve which prevents back flow of plasticated material. Behavior of the back-flow valve during the injection process and its effect on the variations in injection moldings mass were investigated through the analysis of data obtained from the measurements of screw position and nozzle pressure. This simpler method proved to be useful in the estimation of screw displacement, nozzle pressure and material leakage which are required for the closure of the back-flow valve. Factors influencing the injection moldings mass variations were clarified from the material leakage for consecutive runs estimated by applying this method and the corresponding measured injection moldings mass.
