Proposta de redução do alto índice de segunda qualidade de placas MDF em uma empresa de Santa Catarina

Abstract

The present study aimed to propose improvement actions to reduce the high quality index of MDF coated panels in the MDF panel coating line by applying the steps D (Define), M (Measure) and A (Analyze) of the methodology DMAIC. The execution of this study was based on the steps of the DMAIC methodology. In order to collect and analyze the data, we used the defect reduction script elaborated in a spreadsheet software. In which proposals for improvement actions to reduce the second quality index were formulated based on quality tools and management tools. Where the highest index of second quality coated MDF boards in the study was the defect of plaques with torn paper. From this, improvement actions for the problem were discussed, which may highlight relaying among the paper operators, conducting study of paper automation in the coating lines, designing a braking for the roller carriage and changing the laser support for the positioning. The proposals formulated in this study support and guide strategic improvement actions in order to obtain the reduction of the second quality index, in which for future work, it is proposed to perform stages I (Improve) and C (Control) of the DMAIC methodology, for consolidate this study.
