Papers by Keyword: Porosity of Castings

Abstract: In these days in foundry branch there is a rapid development of sectors of special casting technology with the aim to increase the quality and the efficiency of pressure casting production. Internal homogeneity of pressure casting, characterized by the extent of porosity can be affected by the setup of technological parameters of pressure casting and last but not least by vacuuming the moulds, that means to exhaust air and gases from the mould cavity. Contribution is specifically aimed on the analysing the impact of degassing pressure moulds on the porosity of pressure casting from EN AC43400 Alloy.
