Proposta de resolução de problemas de não conformidade em uma empresa de injeção de plástico

Abstract

In this paper it will be a study of nonconformities identified by a company in the automotive industry in one of its suppliers, which manufacture a car aerodynamic set. After conducting an analysis by the automaker professionals, it was found that the supplier suffers from problems which are the main causes of non-compliances identified by the company. The problems are: particle contamination in the paint, inappropriate layout and messy workstations. To eliminate those problems, the strategy was the development of proposed solutions for each of them. Therefore, after the literature review, a solution methodology was prepared with reference to the Simplified Systematic Layout Planning to layout problems, 5S for organization of the main workstations, and application of industrial ventilation concepts to control contaminants. Thereby, for the proposed new layout, it was verified that the investment made with the modifications will be recovered in approximately 9 months, considering the worst case scenario. In addition, with the proposed organization of the workstation, a reduction of 11% in the injection process time was obtained. Finally, a mobile exhaust ventilation system was used at the origin of the contamination to eliminate the root problem. Thus, this work generated a concrete and viable proposal of layout, new workstations organized and the solution of the problem of contamination. In addition, it presents the reader with a new 5S application methodology, since the whole sensory program was developed at a distance.
