This paper addresses the high rejection rate of defective parts in the manufacturing of industrial structures in a metalworking company. The causes include defective raw materials, machinery failures due to lack of maintenance, low staff training, and lack of process standardization. These issues generate rework, production delays, and losses of up to USD 17 333 per year. address this problem, a discrete-event simulation model based on Statistical Process Control (SPC), Total Productive Maintenance (TPM), and the 5S methodology is proposed to evaluate improvements in the production process. The model aims to reduce the defect rate from 10% to 5,2% through quality control mechanisms, preventive maintenance, and technical training.
