Modern conditions of functioning of mechanical-engineering enterprises are determined by the need to develop and to use the technologies for casting products manufacturing with minimal costs for processing. Such requirements are met by the technology of precise casting manufacturing made by complex models. There have been developed technological variants of forming of complex casting models based on the pressing of powder made from the wax-like composition on a metal or aluminothermic unit with subsequent creating of the single-piece ceramic shell. The use of such technological solutions allows to minimize the processing of cast products, to obtain bimetallic castings with high dimensional and geometric accuracy, and realizes the possibility to use the waste of metallurgy (scale and metal chips).
