AUMENTO DE PRODUTIVIDADE NA TROCA DO TIPO DE FLUIDO NA REFRIGERAÇÃO DE MOLDES DE FUNDIÇÃO NO PROCESSO DE BAIXA PRESSÃO EM RODAS DE LIGA LEVE

Abstract

The astronomical growth of the automotive industry in the world and especially in Brazil makes auto parts suppliers work hard to be able to supply this demand and accompany this growth. However, not all auto parts suppliers have the capacity to make major investments in machinery or new factories to meet this need, leaving our engineering, one of the best in the world, to develop or improve the existing production processes to supply this demand. This study aims to demonstrate that water cooling is more interesting for the casting of light alloy wheels, at low pressure, for the automotive industry than for air. Through a comparative analysis between the results of the tests carried out, the technical feasibility was proven, meeting all the engineering requirements that the product in question requires, as requested by the specific customer. Economic viability was proven through the ability to return on investment after six months. Refrigeration is very important for our production goals, as it has a considerable reduction in the refrigeration process time without loss of quality and product reliability, therefore, a reduction in the total manufacturing time, thus reducing fixed production costs. Consequently, we will be more competitive in both the domestic and foreign markets. After analyzing the results, the decision was made to adapt to the water cooling process in all low pressure casting machines of the plant in question.
