Análise do Controle de Qualidade em Baterias Automotivas com Base no Pilar de Qualidade da Metodologia de Manufatura de Classe Mundial A182 F22

Abstract

During the manufacture of products, several variables can influence the production process and final quality. In automobile tracking, as in manufacturing components used in automakers, the sector investigated in this work, quality is one of the most required requirements, so it is necessary to draw up strategies that meet these requirements and also ways to minimize anomalies and nonconformities. The present work was carried out in a manufacturer of accumulators located in the interior of Pernambuco and present in the market at 60 years. The objective of the research is, based on the World Class Manufacturing methodology, to outline strategies and actions that prevent nonconformities in the products. A case study with applied research was developed, the data being collected both through information obtained from the technical assistance sector and through documents of appointments and matrices in the studied sector, in addition to participant observation. The data treatment has a qualitative approach, with a theoretical-empirical emphasis, dealing with nonconformities in the field and in the factory and actions that could control such occurrences. A Pareto chart was used to analyze the most frequent nonconformities and the world class manufacturing methodology to study actions and treatments. The results show that recurrent anomalies in the field are also identified as the main occurrences in the factory, and are also responsible for the main costs with scrap. In addition, it is concluded that the use of the world-class manufacturing methodology, with application of improvement through the application of kaizens, and application of specific tools along the quality pillar, is able to reduce considerably nonconformities increasing the quality in the processes and consequently on the product.
