Abstract
Injection molding is a manufacturing machine that processes the production of small to large plastic packaging that does not have a cavity like a bottle. This study aims to analyze the effect of variations in mold cooler temperature and injection time on the quality of plastic products in multi cavities. The cooling system in the injection molding process affects the quality of plastic products, if the mold is too hot then the melt or liquid plastic will experience a slowdown in the freezing process resulting in defects in the product. This research uses the simulation method, the simulation is carried out to simplify the numerical approach analytically because in simulation it is not only part model, but also injection mold design can be checked and optimized by simulation with the Finite Element Method approach. The software used is ANSYS to obtain the Molding temperature and Autodesk Moldflow Adviser to get product quality. The variations used are temperature 16, 17, 18 with Melt temperature 230 and injection time of 2.4 seconds.
