O custo total de propriedade para auxílio à decisão de compra de molde de injeção plástica: o caso do Pólo Industrial de Manaus

Abstract

In the production of components and final products in Pólo Industrial de Manaus (PIM) the plastic injection process is significantly present. Otherwise, PIM does not produces injection molds but acquire those from other Brazillian states or countries. It allied to PIM logistics and fiscal characteristics takes to question about how wide have being the economic analises to molds acquisition. In this way, this research identifies the Total Ownership Costs (TCO) of plastic injection mold, equationated in a basic model to help purchase decision process, for managers in industrial companies in PIM. For that it was developed an applied and descriptive research, based on bibliographic sources for costs understanding, TCO and plastic injection mold characterization; identification of mold s costs and administrative and economic characterization of plastic injection industries installed in PIM. There was identified 19 elements which reach the various costs happend during and after acquisition of a mold, it together with statistic data about costs in Brazil, allowed to define the importance level for each one in the process, determinanting the five ones more significants, which are: Mold price, logistic, losses from production stop due to mold failure, maintenance material and people. The structure in which this research was developed became by it self a route that guides step by step the implementation of mold TCO in an industry. It starts with definition of expenses types which shall be considered and how to obtain those, then it is determinated a mold evaluation method in industry, being concluded with the classification process, selection and sintesis of TCO elements.
