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)
