Defects in injection molding machine products are analyzed through simulation. The simulation aims to analyze the effect of cooling temperature and injection time on the quality of the injection molded toothbrush head product. Product quality includes quality prediction, weld line, and short shot. The simulation method begins with product design, then determines the simulation parameters including coolant temperature (16, 17, and 18 °C) and injection time (2.0, 2.2, and 2.4 s). ANSYS was run to obtain mold temperature and simulate product quality using AutoDesk Moldflow Advise. Simulation results at a cooling temperature of 16 °C and an injection time of 2.0 s produce a mold temperature of 41.98 °C which has a percentage of product quality reaching 99.6%. Product defects are found in the form of bubbles and shrinkage caused by the temperature of the molten plastic being too high and the cooling temperature too low. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
