Automação do processo de controle integrado de temperatura e tempo de um sistema de queima em mufla para análise de tinta e-coat

Abstract

This work presents the development of an automation system for integrated temperature and time control in a muffle furnace used for e-coat paint analysis in a metalworking company. The currently manual process has limitations such as the risk of human error, lack of standardization, the need for continuous supervision, and the possibility of variations in laboratory results. To address these demands, the implementation of an automated system based on PLC and HMI was proposed, allowing for precise monitoring of process variables, data storage, creation of heating recipes, and safe equipment operation. The methodology involved bibliographic research, analysis of the existing process, definition of components, development of the technical project, and cost estimation. The expected results include increased reliability, energy efficiency, repeatability of analyses, reduced human intervention, and greater operational safety. The project demonstrates technical and economic viability, as well as alignment with Industry 4.0 guidelines.
