This paper discusses the most important input parameters affecting the conventional injection‐molding process and describes a closed‐loop control system for determining the interaction between ten process inputs and three output parameters. The input parameters are: back pressure, holding pressure, injection time, open mold time, shot size, clamping pressure, injection pressure, screw speed, and boost cut‐off. The output parameters studied are: part weight, maximum cavity pressure, and maximum mold deflection.
