Today, in Ukraine, high-technology approaches are widely used in various sectors of the economy. One of these areas is the creation of high-performance microprismal retro-reflective elements. Such items are becoming more and more used, particularly in the transport, road and other industries [1]. The use of various optical retro-reflective devices, which include road signorientation, columns, separating strips and other engineering equipment of highway with retro-reflective elements, can significantly improve driving conditions and night traffic safety, as all road signs with modern highperformance retro-reflective elements become noticeable at a fairly long distance [2-5]. However, the use of modern retro-reflective materials in our country is still not enough, because all these fairly valuable retro-reflective elements and materials are now procured from abroad. As a matter of fact, the production of retro-reflective materials in Ukraine is absent, although today several domestic companies that produce road signs using original materials from 3M and other foreign manufacturers, in particular from China and Poland, are active in the transport market of the country. Therefore, the task of organizing the industrial production of own retro-reflective materials and elements becomes important. To do this, you need to complete a complex mesh of scientific and applied research on the creation of modern light-reflective materials, to develop a technology for the creation of such materials and to design and manufacture special equipment and tools for the release of finished products. It is proposed to develop the optimal design of the circular reflector, to modernize the equipment for the manufacture of a special cutting tool, and to work out the technology of forming it with the use of the matrixes of the originals of the retro-reflective elements, and the technology of galvanic cultivation of precision working matrix dies.
