CANAIS DE REFRIGERAÇÃO EM MOLDES MECÂNICOS: TIPOS E FUNCIONALIDADE

Abstract

Looking at the productive efficiency, industries are constantly looking for new production methods and processes, in which large quantities of similar objects are produced daily. For this, they use formative manufacturing, when the raw material is injected into a mould to achieve a desired shape. Industrial mechanical moulds are widely used for being able to satisfactorily meet industrial demands, but they depend on a range of factors to perform their tasks properly, one of the main points of attention is in the mold cooling, which must be careful, because inadequate cooling will produce defective and low quality products, and may increase the production cycle. For the production of moulds with their proper cooling systems, subtractive or additive manufacturing can be used, each with its advantages and disadvantages, but in general, any object that presents some greater complexity needs additive manufacturing to make a efficient mould, because it is able to build channels that are closer to the object produced. A better project development, based on simulations, leads to changing the shaped channels to branched and capillary channels, with better direction of the refrigerant fluid and can generate objects with higher quality in smaller injection cycles.
