MÉTODO O KAIZEN COMO FERRAMENTA DE REDUÇÃO DO NÚMERO DE REFUGOS NAS PARTIDAS DE MÁQUINAS INJETORAS DE RODAS DE ALUMÍNIO

Abstract

Nowadays companies always need to be among the best, being a reference in production, product quality, always minimizing waste so that your end product always has the lowest manufacturing cost, lead times and also the concern environment, producing more and more polluting as little as possible, The search for continuous improvement is necessary. This paper aims to present a case study of the continuous improvement methodology, Kaizen applied in matches and setups of aluminum wheel injection machines. The project was carried out in the foundry of Mangels S.A, the country's leading supplier of aluminum wheels. Proving that with the proper use of the methodology tools, it was possible to verify the failures in the injection process, always in the tool starts and changes, reaching the cause root of the problem that the temperature at certain points of the tool was below ideal injection due to sufficient heat torch causing high departures. Today the problem has already been fixed with the new but efficient torch which has decreased the scrap rate yielding profits and improving the quality of the final product.
