ANÁLISE DO PROCESSO PRODUTIVO DE RODAS DE ALUMÍNIO APLICANDO AS FERRAMENTAS DA QUALIDADE COM FOCO NA INVESTIGAÇÃO DE DEFEITOS DE FUNDIÇÃO

Abstract

The paper discusses the importance of quality in the production process of aluminum wheels, highlighting its relevance in view of the competitiveness of the current automotive market. The focus of this work is to analyze in detail the flow of the casting process, where the aluminum wheel is born, and to present the resolution of product quality problems such as porosity, which can be detected and solved aiming at the improvement in the following processes. Emphasizing that the essential for obtaining an aluminum wheel that meets the customer's requirements is to obtain a cast product with high rigor of controls and monitoring that make this result possible. The work shows the importance of adding each chemical element during the casting of aluminum and what changes occur in the mechanical properties of the product through these additions. During the development of the work, several quality tools are presented that can be used and applied by the management and specialized team in the casting area to detect these defects. Several satisfactory results are presented through process parameter checks and changes aimed at small improvements, but that together they present significant results.
