Fundição de precisão para a produção de peças de zinco com geometria complexa

Abstract

In the foundry laboratory of the UFC(Federal University of Ceará), new precision casting techniques were developed to reduce costs using recycled materials such as scrap and residual ashes from thermoelectric. In addition, the preparation of the model pieces, the use of silicone for the production of molds, preparation of the wax modelsand leakage channels, manufactureof the refractory ceramic cast, leakage of the metallic alloy (ZAMAC), obtaining the rusticpart and the machining process. In this way, we conclude our project giving usefulness to a polluting material and recycling zinc scrap and, consequently, lowering the costs of this process and may also be the generation of employment for poor communities.
