The bottle mold used in this study is shown in Fig. 1.
The preform was generated by Blowview version 8.4 (Fig. 2). Fig. 3 shows
a typical temperature profile of a preform just before it is stretched
and blown into the bottle mold. The preform temperature profile
was defined by three points Sp1, Sp2, Sp3 recorded by thermal imaging camera.
The temperature profiles following preform cooling times of 2, 2.5, 3, 3.5 and 4 s are shown in Table 1; this experimental data was input to the simulation studies.
