In-cavity pressure measurements for failure diagnosis in the injection moulding process and correlation with numerical simulation

Abstract The pressure profile analysis for monitoring and diagnosis processing failures during an injection moulding process, such as burn marks short shots, is a useful instrument process part quality control production with zero defects greater efficiency. Therefore, this work aims to demonstrate the in-cavity feasibility failure optimization. methodology used analyse obtained variation presented. results were correlated typical cavity profile, which enables acquisition of information about tool. This way, it was possible determine origin present in injected parts, focusing not only on velocity switchover but also initial curve, related filling phase. Moreover, studied conditions simulation.
