Definition of the rational technological mode of low-pressure casting

The object of research: the technological process of manufacturing a cylindrical casting using the low-pressure casting method. Investigated problem: determination of the patterns of influence of technological parameters and casting dimensions on low-pressure casting modes and process efficiency indicators according to selected criteria. The main scientific results: the linear relationship between the compressed air pressure in the receiver and the mold filling duration, concerning the applied pressurization pressure, was established for selected characteristic sizes of castings made of copper alloy. A regression equation was developed to determine the receiver pressure that ensures the minimum mold filling time with the alloy. The area of practical use of the results of the study: technology for manufacturing castings using low-pressure casting. Innovative technological product: technological regimes of the low-pressure casting process for copper alloys. The scope of the innovative technological product: technology for manufacturing castings for a wide range of applications, particularly in mechanical engineering
