Abstract
A method for evaluating moldability characteristics of a plastic resin in an injection molding process. A vital few process response variables are determined from a plurality of process response variables that are used to characterize the injection molding process. The vital few process response variables control a plurality of quality characteristics that are used to characterize a molded product made from the plastic resin. An empirical model is then developed describing the relationship between the vital few process response variables and the plurality of quality characteristics. The empirical model is then trained with experimental data taken from injection molding process runs using new grades of the plastic resin. The trained empirical model is then used to evaluate the moldability characteristics of new grades of the plastic resin.
