This study analyzes the temperature spread distribution in the core and cavity design of a manual
double-stage injection molding machine with a 5 tons force (TF) capacity. The injection mold is
utilized to process polypropylene (PP) material into an injection product in the shape of the PNJ
logo. This research aims to examine the temperature spread distribution resulting from a 100-watt
cartridge heater located on the support plate of the mold, with a focus on the core and cavity
temperatures. Manual calculations using heat transfer conduction principles and finite element
analysis (FEA) simulations using software were conducted in this study. The parameters
investigated include the temperature values across the support plate mold, core, and cavity. The
results of the manual calculations indicate that the temperatures on the support plate mold, core,
and cavity are 58.96°C, 57.34°C, and 57.34°C, respectively. The simulation analysis yielded
maximum temperatures of 89.53°C for the support plate mold and 88.11°C for both the core and
cavity. The manual calculations and simulation analysis produced accurate and reliable results,
confirming that the standard mold temperature range for processing polypropylene is between
20°C and 90°C. This analysis demonstrates that the identified temperature levels are safe for
polypropylene processing, providing high confidence in the validity of the research findings.
