Scrap Reduction Due to Mechanical Failures in Heart Failure Medical Devices

Abstract

This research addresses the critical issue of reducing scrap in the manufacturing line of medical devices for heart care in Puerto Rico. Currently, manual assembly processes pose risks of mechanical failures, leading to significant financial losses and potential harm to patients. The project aims to identify root causes of mechanical defects, quantify associated costs, and implement measures to reduce scrap by 50% and improve manufacturing line yield by 5%. Employing the DMAIC methodology, the study involves data collection, analysis, and targeted interventions. Key improvements include implementing standardized work procedures, optimizing welding parameters, and enhancing maintenance protocols. Statistical analysis demonstrates significant enhancements in process capability, with notable reductions in rework instances and associated costs. These interventions result in tangible economic benefits and improved product quality, underscoring the effectiveness of continuous improvement initiatives in achieving sustainable manufacturing excellence. Key Terms ⎯ Cost, DMAIC, Reduce, Rework, Scrap.
