A practical investigation was carried out to monitor and understand the production process, and based on the theoretical framework, actions were proposed so that the objective could be achieved. The actions helped to define the process parameters, emphasising the furnace time, which was identified as the main cause of problems with non-conforming parts. From the results obtained, it was concluded that energy efficiency in a production process does not necessarily require high investment. In addition to the economic factors, the study enabled adjustments to be made to the internal procedures of the company sectors involved in the production process.
