description: The object of research is burned-out and lost-wax models in foundry. The technological part of the work the requirements for ensuring the required level of quality of castings and their high manufacturability are presented, various methods of manufacturing casting molds are considered, such as molding into a sandy-clay mixture, into cold-hardening, casting according to investment and burnout patterns. The equipment, which is used in foundry for the manufacture of castings by the method of investment casting and burned-out patterns, is described, the advantages and disadvantages of these types of casting are described. In a special part of the work, a comparative analysis of the manufacture of castings using burned-out and lost-wax patterns is provided, methods of obtaining expanded polystyrene, its properties and chemical composition are studied. Technological operations of making models are presented. The equipment for each of the methods with a detailed description is considered, materials for the lost-wax and burned-out models are presented, the positive and negative aspects of each of the presented processes are given. The classification of defects for these types of casting and methods of their elimination are considered. The analysis of the work done is presented in a graphical form and is accompanied by conclusions based on the results obtained during the comparison of methods
