Article Abstract

[This abstract is based on the author�s abstract.]

Although simple in concept, the injection molding process is much more complex in execution. Molders have traditionally sought the best molding condition through a combination of experience and trial and error. This method, however, is costly and time consuming. Researchers have attempted various approaches to determine process conditions that will reduce time to market and result in higher quality. One of the most efficient methods is the design of experiments (DOE), which consists of purposeful changes to the inputs of a process to observe the corresponding changes in the outputs.
