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. Experimental casting was manufactured with elevated temperature of mould (370 K). Lower and stotted ingate with high geting system (300mm) was used. Analysis of ability of metal to fill the mould cavity in establish technological conditions was perfomed. Degree of refinement of structure in typicall region of skeleton casting was compared. Qualitative different degree of fineness of eutectic was confirmed. Selection of modification conditions AlSi alloy of skeleton casting is necessary. The manufacturing of skeleton casting in establish technological conditions enables obtained very good filling of mould cavity and suitable external geometrical form of casting.
