TABLE 2
A plastic injection molding process is often used in manufacturing because of its ability to mold complicated
shapes. An experiment was conducted on the manufacture of a television remote part, and the warpage (mm) of the
part was measured and stored in TVRemote. (Data extracted from M. A. Barghash and F. A. Alkaabneh, "Shrinkage
and Warpage Detailed Analysis and Optimization for the Injection Molding Process Using Multistage Experimental
Design," Quality Engineering, 26, 2014, pp. 319-334.) Two factors were to be considered, the filling time (1, 2, or 3
sec) and the mold temperature (60, 72.5, or 85° C).
