Optimización del proceso de producción en serie mediante la implementación de Lean Manufacturing para mejorar la calidad de producción de bisagras en una industria metalmecánica

Abstract

Abstract: The purpose of this study was to improve the hinge production process in a small metalworking company by applying Lean Manufacturing principles during the PDCA cycle and emphasizing the 5S method. To this end, a process diagnosis was first carried out, identifying waste such as unnecessary movements, waiting times, and defects that affected productivity and quality. This was followed by measures aimed at order, classification, cleaning, and standardization of the workplace, which resulted in reduced cycle times, greater operational efficiency, and lower defect rates. Operational discipline was also strengthened through internal audits, visual controls, and work procedures, which made it possible to maintain the improvements achieved. The study demonstrated that without major investments in machinery, the application of Lean tools helps improve process performance in metalworking companies, leaving opportunities for continuous improvement in place. Overall, experience has shown that visual control, order, and standardization are key elements in increasing competitiveness in production environments with limited resources.
