Aplicação do ciclo PDCA para redução da produção de latas não conformes em uma fábrica de leite em pó

Abstract

Reducing waste in production has become a crucial issue for industry professionals, and it is the foundation for decision-making for both big and small companies. Therefore, this study was conducted in a milk powder factory located in the city of Ituiutaba, in the state of Minas Gerais, Brazil. The objective of this study was to implementing the PDCA (Plan, Do, Check, and Act) cycle to reduce the production of non-conforming cans, which generate waste, such as rendering the cans unusable, tangles and unplanned line stops in a powdered milk factory. The quality tools Cause and Effect Diagram and Brainstorming were utilized. The primary outcomes of the study include the identification of the root causes of the problem, the implementation of standardization and process improvement actions, which resulted in an average defect reduction of 71%. Additionally, the study showed that the problem of dented cans was entirely eliminated during the three months of project effectiveness analysis.
