Diagnóstico de defeitos em uma linha de produção de uma industria da linha branca

Abstract

In a market as competitive as the home appliances industry, the search for higher quality and lower production costs is incessant. Aiding this search there is quality management, which seeks to identify problems and assist in finding solutions. For this, there are quality tools that help in organizing data and presenting defects, causes and possible solutions. The identification of flaws makes the product reach the consumer without any quality problem and the identification of causes leads to the study for corrective actions. Using a literature review of key quality tools such as Pareto Diagram and troubleshooting methods such as PDCA and the 5W2H tool. Quality inspection data were collected from one month of typical production. Data were grouped by production lines and a one of those production lines was selected for analysis. The quality defect information of this production line was then sorted and organized for a problem-solving proposal. With the case study it was possible to diagnose the production line and solutions to the most common defects were proposed. It was also possible to evaluate the use of the Pareto diagram and the 5W2H tool in a home appliances industry.
