Technological yield of castings (TYС) and the utilization rate of the metal of cast parts (URM) are indicative indicators of the level of foundry development. These aspects of the future development of the foundry are considered in the area of creating new and improving existing technological processes of forming, smelting and casting methods. The most acute problems in solving these tasks are as follows: reducing the mass of cast parts due to careful design and technological study of the geometry of the part, selection of the alloy with regard to the casting technology, use of computer simulation, organization of the hydrodynamic process of filling the mold with liquid metal, taking into account the formation of flows directly in the form, the intensification of the work of heads, improving the properties of alloys in the smelting process; improving the geometric accuracy of castings by introducing new methods of forming, molding materials; organizational measures to reduce metal losses in foundries; widespread introduction of heat treatment of castings in various ways for various alloys; expansion of the composite casting nomenclature, which allows to synthesize individual casting elements that meet the requirements of operational reliability; professional development of specialists working directly in the shops, research institutes, universities, the NAS of Ukraine; creating an image of the attractiveness of the caster profession by improving working conditions, the environmental and sanitary situation through the use of new materials and technologies; the active introduction of nanomaterials into technological processes, which makes it possible to sharply increase the mechanical and service properties of castings; synthesis of new, more efficient production processes based on additive technologies using 3D printers. The considered technological processes solve this dual problem.
