Eventos Kaizen aplicados no processo de linha de montagem SMT para redução de tempo de set-up: estudo de caso

Abstract

This work was aimed at applying the tools of the PRS System (Lean Production), whose primary tool was crafted VSM (Value Stream Mapping), a process known as SMT (Surface Mount Technology). Principles for lean production, eliminating waste and creating value stream in a real situation through kaizen events, were used to obtain results of this application, showing a lean transformation, with significant reductions in waste generated in the process. The study period was eight months into a private company located in PIM, where through the use of tools of this system and methodology of action research, it was possible to identify the critical process - setup - where focused improvement actions. With the change in the system setup, the standard work and creating a setup program using visual aid, favoring the continuous flow in this process. During the research, trainings were conducted in the factory with the operators, leaders, supervisors and engineers responsible, who participated actively in the improvement actions. Therefore, through value stream mapping, we propose to draw the current state of the stream, offering a future state, identifying and eliminating everything does not add value. To quantify the increase in productivity on the factory floor and total earnings of areas in the factory.
