Diseño de una matriz con mayor número de cavidades para la fabricación de piezas industriales mediante sinterizado

Abstract

Sintering is a precision manufacturing process for producing industrial components in large series, without material loss, highly reliable and economical. In one phase of this manufacturing process, metallic powder is subjected to a pressing process, after which metal particles are joined together due to the mechanical deformation suffered. This pressing process is carried out in moulds, in which the cavities that will give rise to the green compact manufactured by pressing are mechanized. The aim of this study is to design a new mould with more than 5 cavities, which is the number of cavities in the current one. If this new mould were achieved, then an increase in demand could be satisfied. The new mould must fulfil the same strength and fatigue requirements, as well as economic criteria, imposed to the current mould. As conclusion of the work carried out, different configurations when designing the mould with more of five cavities are obtained. All of them fulfil to the existing strength and fatigue requirements.
