Abstract

The high industrial competitivity has dictated the development for this sector that allied with the inconstant and unstable economic environment make the companies very vulnerable and highly dependent of the surrounding market. This is a concern of special relevance for the SMEs and companies are increasingly adopting Lean solutions to continuously improve their operations. The objective of this study is to diagnose a production system of an injection mold structure production factory. The diagnosis was focused on many aspects such as the part production lead time, a time study of the setups, the OEE determination for the CNC equipments and an analysis of the work stations. For the aspects that were analyzed during the diagnosis the problems are identified and the root causes determined. At the end of the diagnosis stage Lean solutions are proposed like new rules for production planning, setups procedures, 5S, and a Lean implementation plan that is adapted to the company of this case study. For some of the solutions an impact study with their implementation is made. Is also made an analysis of the success and unsuccess factors proposed in the bibliographic review that were verified during the diagnosis stage of the case study factory.
