In this article authors showed method for manufacturing of skeleton castings with continuous external surface. Wall thickness of the external surface was 6 mm. The experimental casting was manufactured in order to verify the results of filling mould cavity which were obtained by numerical simulation. The aluminosilicate core was used to produce experimental aluminum skeleton castings with dimensions of (115x65x136) mm. Lower ingate with vertical getting system was used. On based on numerical simulations and preliminary experimental tests technological conditions were determined, which enables obtained castings on repeatable satisfactory geometry and requirement quality. Degree of refinement of structure in typical region of skeleton casting was compared. Qualitative and quantitative different degree of fineness of eutectic was confirmed. Selection of modification conditions AlSi alloy of skeleton casting is necessary. Based on tests, which were performed authors deduced, that manufacturing of skeleton castings is possible with use of traditional casting technology, without use of expensive laboratory – devices, with applied classical gating system and typical pouring temperature of Al alloys (ex. 740°C).
