Aplicação das ferramentas da qualidade para a redução das perdas de qualidade numa linha de fabricação de massas

Abstract

The competition between companies that work with production in general, forces them to implement improvements in their management and control systems, aiming to reduce losses in production processes. This work was developed in a pasta factory located in the city of Jaboatão dos Guararapes in Pernambuco. The objective of this work was to diagnose and reduce losses in a pasta production line. A survey of losses was made in a production line of Ninho noodles, for a period of six months. The cost of existing losses was estimated, and the responsible sector stipulated a 40% reduction in this cost in the line under study. A study of the operation of this line was carried out. It was found that the main sites for reprocessing were in the press, in the drying tunnel, in the wire mat and in the elevator belt. Thus, from the 5 whys tool, the root causes of the problem were obtained: wire and elevator belt. From the application of the PDCA cycle, the actions were successfully carried out with a reduction of 61% of the non-conformity of the Reprocessing in the Nest-type noodle line. This loss reduction in the four months of the project due to Reprocessing, generated an annual gain of 25.1 ton/year, which means an annual gain of R$ 115,290.00 for the company.
