Desenvolvimento de procedimentos operacionais padrão para a criação de pequenas fundições.

Abstract

The better our processes standardized the better they become. With well defined processes we can accelerate our development in a sustainable way. In the present work, a study was made on the lost wax casting process of the Foundry Laboratory of the Federal University of Ceará (UFC). The process that occurred in the laboratory had neither documentation nor standardization. The process of manufacturing lost wax pieces went through a series of experiments until the ideal manufacturing formula was reached. With the experiments, a study was also performed on the defects present in the final pieces, this study was crucial for a better understanding of the casting process. The list of actions necessary for the success of the foundry was put in the Standard Operating Procedure (SOP). Because of the simplicity of the process used, it is believed that it can be replicated in other environments outside the university. This process can be a source of income for many families in Brazil, and a low investment is necessary for its beginning.
