The measured results in Tables 4–6 showed that
the pin and triangular fins improved the heat
transfer rate and molded parts with an approximate
15% reduction in the heating time and cooling
time. The HTR and CTR of molded parts were
not significantly affected by the weight of material
charges, as shown in Table 4. Interestingly,
the HTR and CTR of the fins decreased with
the oven temperature (Table 5) and the mold’s
rotational speed (Table 6). Furthermore, the enhancing
effect of the pins was significantly reduced
when a fast cooling condition was used (e.g., water shower)
