MELHORIA NO CONTROLE DA EFICIÊNCIA DO SISTEMA DE REFRIGERAÇÃO EM MOLDES METÁLICOS: Desenvolvimento de um teste na refrigeração durante setup.

Abstract

This work deals with the implementation and testing of a device designed to improve the control of the efficiency of the cooling system of molds used in casting, in an aluminum wheel manufacturing company, during setup. The main objectives were to reduce delays in setup related to problems in the cooling circuits and improve the effectiveness of these circuits in production, factors that negatively impacted productivity. In order to achieve the main objectives, pertinent bibliographic reviews, analyses of the processes related to the company's casting sector, development and testing of the device were carried out. The device was tested in June 2024, and through this test it was possible to collect data to prove the feasibility of the improvement. The data indicated a total elimination of delays in setup related to the cooling system, previously responsible for production loss. In addition, the introduction of the device allowed for more precise control of the mold temperature, resulting in improved thermal efficiency and greater uniformity in casting. There was also a significant reduction in part defects and an increase in the useful life of the molds, thanks to targeted preventive maintenance based on monitoring of the circuits. The positive results point to the viability of expanding the use of the device to other areas of the production process, promoting additional gains in efficiency and quality in the production of aluminum wheels.
