Analysis of casting flaws into the pistons materials obtained at the different conditions of casting: values changing of melts flows, adding of the second vent, adding of a feeding point, a metal mold tilt and changing of the casting orientation into the mold was performed. Rapid cooling of aluminium melt leads to incomplete filling of the metal mold channels without additional elements of a gating system. Complete filling of the mold and the lowest deformation of material after cooling are ensured by changing of the aluminium casting orientation into the mold (by 180 degrees). Casting of the cast iron pistons is recommended to perform by adding of the second vent and the feeding point, as well as when the metal mold tilt by 90 degrees.

“…Литье цветных сплавов осуществляется под высоким давлением, в кокиль, и в случае изготовления крупногабаритных отливокгравитационным литьем. Величины линейной и объемной усадок отливок, изготовленных из некоторых марок сталей, чугунов и цветных сплавов, представлены в работах [1][2][3][4][5][6][7][8][9][10]. Усадка является естественным физическим процессом.…”
