Abstract
The thermoplastic injection process, in the production of large-scale parts, requires that the molds used in the environment have high quality, in order to maximize their productivity, with the lowest scrap rate. In this context, numerical simulation, as a method for analyzing injection molding processes, can contribute, together with mold manufacturing companies, in solving failures, conventionally detected only in injection, providing their customers with the required quality. The study applies to a product injected in ABS material, through a mold containing four cavities, which showed injection flaws on the apparent surface - posteriorly to the feed channel. Through experimental analysis, an attempt was made to contemplate a technical solution, where, by reading the behavior of the molten material under virtualized processing, it was possible to understand the aspects that influence the malformation of the injected component, as it was already empirically suggested that they were linked, among other factors, to the trapping of gases in the cavities. The numerical diagnosis obtained through the CAE simulation allowed the designer to validate the process and verify the processing reactions, under different injection parameters, and to guide him to the improvement of the gas outlet system.
