Impact Factor:ISRA (India) = 1.344 ISI (Dubai, UAE) = 0.829 GIF (Australia) = 0.564 JIF = 1.500 SIS (USA) = 0.912 РИНЦ (Russia) = 0.234 ESJI (KZ) = 3.860 SJIF (Morocco) = 2.031 ICV (Poland) = 6.630 PIF (India) = IntroductionToday JSC «Vladimir electromotive plant» (Russia) carries out the manufacturing of accessories and the assembly of the low voltage electric motors by power from 0.75 to 315 kW [1]. The main products of the enterprise are the three-phase asynchronous motors for the general industrial use. The motors of the special modification (explosionproof, single-phase, for the drive elevators, for the electric hoists and etc.) are produced also.

Influence of a Mold Material and Percentage of Chemical Elements in Melt on Shrinkage of Castings Made of Nonferrous Metals Alloys.

“…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.…”

Simulation of the Technological Process of High-Pressure Die Casting of Silumin

“…Due to combination of high velocity of melt injection from a chamber of a die casting machine and high pressure, a casting material is cooled in several times faster than when casting in sand moulds [2]. Rapid cooling of melt in the mould is contributed by improvement of the mechanical properties of the casting, getting of high surface finish and high dimensional accuracy, increasing corrosion resistance.…”
