Study on the Automation Effects of the Injection Molding Process

Abstract

This study explores the design and implementation of the first automated injection molding system, replacing themanual process, utilizing articulated robots for the production of moving hanger mounts in garment care systems. The proposed system enhances manufacturing efficiency by reducing cycle time from 83 seconds to 22 seconds,resulting in a 23% increase in hourly production output. Additionally, the defect rate decreased from 25% inmanual production to 15% with the automated process, marking a 40% improvement in product quality. Theintroduction of this automation also led to an 82% reduction in manual labor hours, streamlining operationssignificantly. The economic analysis projected annual savings of approximately 93.548 million KRW, with animpressive return on investment (ROI) of 69.07% and a payback period of just 1.43 years. Overall, the findingsindicate that the integration of robotic automation not only improves productivity and product quality but alsooffers substantial long-term economic benefits for manufacturing processes
