Application of Lean Manufacturing to Reduce Unproductive Times in a Valve Spring Inspection and Packaging Cell

Lean Manufacturing (LM) is a philosophy that allows companies to be elevated using their tools and contribute to the improvement of sectors. Therefore, it is necessary to adopt this system in order to continuously improve it, therefore, the general objective of this research was to analyze the feasibility of implementing the lean manufacturing tool in a valve spring inspection and packaging cell. To do this, specify the following specific objective, determine a method capable of increasing production capacity through LM, in order to increase competitiveness and profitability and evaluate the time results provided by LM. An action research was carried out to understand the benefits of applying this study in an inspection and packaging cell through the use of practical activities in company X. The results show that using tools such as the Ishikawa Diagram it is possible to use the cause root of the problems, thus allowing to develop actions to solve the problems. Thus, it was possible to verify that, when discovering the problems, it can increase by about 15% in area 1 and 9% in area 2.
