The search for productive efficiency is a constant need for companies that aim to continue their activities in an increasingly competitive market and that present constant innovations. For this, many of them, in addition to being aware of technological innovations, also promote internal improvement programs in order to obtain viable solutions and with the certainty of a return on investment. Aiming to propose improvements in real industrial processes, the present work deals with the study of the preheating of metallic molds in a pressure casting process that uses ZAMAC alloy as raw material and has as main objective to show the feasibility in the implementation of this process. The applied methodology comprises bibliographical research and simulation of the implementation of this process in a company that has a casting sector that includes the necessary specifications. At the end of the work, the conclusion is reached that it is feasible to implement the preheating process of molds in the casting sector of the studied company, based on the results obtained related to the technical and mainly financial aspects, where there is a return on investment in 10 months due to the production gain evidenced.
