A method and system for controlling a fluid-assisted injection molding process for producing a molded plastic article. The fluid can be gas, water or another fluid. One or more pressure transducers are positioned in the mold cavity and generate signals to control the initiation of the pressurized fluid, the packing of the material in the mold and/or the switchover from the packing phase to the holding phase. The transducers can be positioned at or near the gate or pre-gate, at or near the fluid channel area, and/or at or near the end of the fill area.
