In this article authors showed method for manufacturing of closed skeleton castings with hypo - eutectic and eutectic aluminium alloys. Experimental castings were manufactured in variables technological conditions: range of pouring temperature 680÷740 °C, temperature of mould 20÷100 °C and height of gating system above casting level 105÷175 mm. Structural analysis of studied skeleton castings was conducted. Degree of refinement of structure in typical region of skeleton casting was compared. Qualitative and quantitative different degree of fineness of eutectic silicon was confirmed. Casting in established technological conditions enables manufactured skeletons which repeatable geometry, suitable external geometrical form of casting and required quality.
