Application of Lean Production Principles and Tools for Quality Improvement of Production Processes in a Carton Company

This work presents an industrial case study focused on improving the quality of production processes, using lean production tools. The analysis of the initial situation was done using cause-effect diagrams, Pareto's analysis, study of setup times and performance indicators, allowing identifying the main problems, such as high setup times, low availability of machines, lack of organization in the working area. Improvement proposals were implemented in the bonding section, like the SMED methodology, the 5S technique and visual management. As result it was achieved an average reduction of 47% in the setup time, corresponding to 10114€ of monthly profit.
