Redução do custo da não qualidade na linha de produção do pistão 6CVC: mapeamento e controle dos parâmetros de processo ligados à temperatura

Abstract

Business today have faced increasing competition and the high velocity of change imposed increasing pressure as well. That said, there is a need to operate processes in a lean and six sigma environments, which fulfil customer needs, and at the same time, assure good results for all business stakeholders. Results based on ROI (return of investment), intellectual, team moral and team satisfaction. The structured DMAIC method with the tooling, combining the lean manufacturing tools and six sigma tools assure a long-term condition when searching for increasing results and profitability. These Project presents the implementation of a design of experiment based on the lean six sigma strategy in the production of aluminum platters to the automotive industry which are dedicated to the air condition systems in a medium size automotive company situated at Curitiba metro area which supply components in the global market. A Project Charter was built and submitted to the board of directors with all premises, restrictions and project scope. The data focused mainly at the voice of the customer and with planned return of non-quality cost and productivity gain chained with the corporate mindset elevation to a higher level. A set of design of experiments were run and optimized process equation obtained. An action plan was implemented and results collected in prototype scale which were, afterwards, implemented in the process. Economic results, FTQ over 99% and additional sales over R$ 1,000,000.00 projected yearly, were obtained during the course of these Project and validated along the control step.
