Lean Manufacturing: A perspective from operational efficiency and the sustainability of machining processes in a metalworking company in Cartagena

Abstract

The constant search for improvements in production processes has led to the adoption of innovative approaches that improve operational efficiency in companies in the metalworking sector in Cartagena. In this research, we worked with a representative company of this sector which faced a significant problem related to the deficiency in the standardization of processes, which generated an increase in the production of defective products, a reduction in operational efficiency, delays in deliveries. In this context, this project emerged as a strategic response to address the deficiencies identified in the company's machining process. The purpose of this was to apply an innovative approach based on tools and principles of lean manufacturing, by eliminating mudas, elements that do not add value to the product or service. The Lean Manufacturing proposals designed were presented as a solution, where the tools of this methodology were applied in an integrated way to identify opportunities for improvement, reduce production times, minimize costs and standardize activities related to the machining of blocks and cylinder heads. This project was not only conceived as an initiative to overcome operational challenges, but also as an opportunity for improvement for companies in the sector, which are beginning their growth process.
