Abstract

In this work, it was done a case study within a plastic packaging thermoforming company aiming to reduce the high waste index of materials throughout the thermoforming process. To solve the presented problem, firstly it was made a mapping of the waste index for all the machines and then for the whole sector in the year of 2017. Subsequently, supporting tools to management production were used, such as the Ishikawa and Pareto diagrams, Lean Manufacturing and the WCOM methodology, which provided theoretical support to the formulation of improvement actions to be implemented in the company. The application of these actions and their efficacy were analyzed considering the preceding and following state of the initiatives. With the introduction of the actions, there was a financial benefit for the company of hundreds of thousands of reais. Finally, it has been concluded that such actions were successful solving the presented problem, and ideas that can still be deployed to further improvement of the company index and gain opportunities are shown as well. Due to the good results here presented, there is an intent to adopt similar measures in other productive processes of the company.
