Gestão da qualidade: implantação de um sistema de gestão da qualidade em uma fábrica de telhas de concreto

Abstract

This study presents a discussion on the implementation of a quality system in a factory of concrete tiles in order to minimize the rate of spoilage of the final product. To achieve this goal, we first performed a data collection in order to get the real picture presented by the company, so it was identified that there are three kinds of defects that were treated as breaking: breakage, deformation and cracking. It was also considered critical operations in the process, that is, where largest number of breaks occurring. To conduct this survey were used some quality tools described in the literature review. As a prerequisite for the implementation of a quality system has identified the need to implement an organizational system called 5S. It was found that after this deployment the company showed a significant improvement in the organizational and behavioral. The PDCA cycle method improvements, the system was used to achieve the research objective. The implementation of this method was given following four steps. Starting with the Planning module, which were found to cause the effect in question and thus made possible the development of an action plan for each critical operation. In the second stage the action plan was put in place. The third module consisted in analyzing the results achieved by the plan, and finally, the fourth stage were standardized proposed actions. At the end of the survey it was found that the objectives were achieved, and the rate of waste reduced about 33%, from 8% to 5.3%, confirming the hypothesis of the research that through the implementation of the quality system Cycle PDCA the company entered into a system of continuous improvement in adding quality production process thereby reducing the rate of scrap.
