Analysis of coolant temperature and injection time effect on the product quality in injection moulding using the Finite Element Method (FEM)

Abstract

The purpose of this research is to analyze the effect of cooling temperature and injection time on the injection molding machine to product quality using the finite element method. The first step in this research a designing cavity molding and plastic product with AUTODESK INVENTOR 2019 PROFESSIONAL software. The next step is found the average temperature in molding use the ANSYS software. The results are then used for the process of analyzing the quality of plastic products. The next stage is the process of analyzing the quality of plastic products using AUTODESK MOLDFLOWADVISER R2 2017. The plastic product analyzed is a product called plug-ib, the product used in eye drops that are obtained from plastic manufacturing companies, namely PT. Berlina Tbk. The results obtained by a cooling temperature of 24 °C with an injection time of 1.4 seconds obtained the quality of the best product with a percentage of product quality of 79% and a product weight of 0.415 grams.
