Redução do retrabalho causado por má aplicação de verniz interno em embalagens metálicas

Abstract

This work had as objective to control the failures of internal coating in aluminum cans in relation to previous years, which corresponds to the loss of credibility of the company towards its clients and to reduce the high cost of rework that as failures not coating caused. The Six Sigma methodology, with emphasis on the DMAIC tool, which defines, measures, analyzes, improvements and controls the process, guides the sequence of activities developed. The theoretical research was based on articles and manuals that seek the practical application of methodologies in industrial systems with low efficiency, high maintenance cost and low reliability. When applying the methodology such as the FMEA (Failure Mode and Effect analysis), it was identified the need for training and understanding of the physical phenomena involved in the process, as well as to create conditions for the understanding of the failures occurred, improvements in the processes to solve chronic quality problems and control measures. Devices for data collection and real-time information generation have been developed, capable of ensuring the correct application of coating varnish applied to aluminum cans, generating consumption reports and specifications to improve operational decision-making on product quality in manufacturing. The work evidenced the deficiency of the internal varnish applicator equipment, which entailed rework and waste of inputs, due to the lack of knowledge of the adjustments and process variables. It showed that it is only through knowing the processes involved in manufacturing a product that truly effective improvements can be implemented.
