Implantação de um Sistema Automático para Supervisão do Abastecimento de Água no Processo de Injeção Plástica: Estudo de caso em uma empresa do Polo Industrial de Manaus

Abstract

This work presents the development of a project focused on the automatic supervision process through a supervisory system dedicated to the water supply in the plastic injection area in a factory environment. The purpose of the project is to avoid lack of water in the plastic injection process. The process engineering concepts employed here are intended to visualize the entire process, identify the problem and its root cause, and propose solutions to eliminate constant occurrences of water shortages. The study of the problem occurs in a factory environment that we can describe as follows: the employee is responsible for manually monitoring the tanks, but performs other activities in parallel, thus the manual monitoring applied is totally ineffective generating several impacting occurrences: unavailability machine costs, rising costs, not meeting goals, compromising the performance of the organization. It is necessary to implement this project because it reduces human interference, minimizes errors, ensures the supervision of the entire water supply system in real time, anticipates decision making in case of any problems with the pumps. As a result of this research, we concluded that with this project, we eliminated 100% downtime of machine injectors due to lack of water, increasing process reliability and reducing total waste of 25.8 tons of raw material per year.
