Performance Evaluation and Optimization of Injection Molding Using the SMED Method

ABSTRACT Continuous improvement in manufacturing requires systematic performance evaluation and targeted optimization actions. This paper presents the application of the SMED (Single Minute Exchange of Die) methodology for performance evaluation and optimization in an injection molding production environment. The study focuses on reducing setup and mold changeover times, minimizing micro‐stoppages, and improving process stability through the identification and elimination of non‐value‐added activities. The effectiveness of the implemented improvements is evaluated based on the reduction of changeover duration and production downtime. The results demonstrate significant reductions in changeover time and production interruptions, leading to increased production capacity and improved process stability. Although the study is based on a specific industrial case, the proposed approach can be adapted to other manufacturing environments, aiming to enhance flexibility and reduce operational waste.
