description: The topic of the final qualifying work: "Research of properties and development of technology for manufacturing molds for casting aluminum alloys with the use of gypsum as a binder". The purpose of this work is to study modern methods of casting aluminum into gypsum molds, analysis of the composition of mixtures for the manufacture of molds in order to reduce the shrinkage values of gypsum samples. The solution of this goal has practical significance and is economically beneficial for many companies. The use of expanded polystyrene significantly reduces production costs, and most of them fall on the manufacture of tooling and models. Tasks that were solved during the study: General concepts are given and the main equipment for the production of complex aluminum castings by the LGM method in gypsum molds is given. Experiments were carried out to determine the size of gypsum samples with different water content, measurement of dimensions during heating, as well as tests for compressive strength. The composition of the gypsum mixture has been selected, using which it is possible to achieve the lowest shrinkage values. The cost of manufacturing molds is calculated.
