Computer Modeling of Casting Processes for Centrifugal Pump Parts

The paper describes the application of computer programs for modeling foundry processes – casting metal blanks. Several casting objects (samples) of varying complexity were used in the simulation. A 3D model of the part and casting of a higher-quality multifunctional mold for casting in the SolidWorks program was developed. Defects in drawings were also automatically eliminated. The NovaFlow&Solid and MAGMASOFT programs were used to calculate the formation of shrinkage shells. The NovaFlow&Solid program is best used for checking simple and small models. It performs calculations quickly enough, but the accuracy of this program is low; therefore, when calculating complex models, it may give incorrect results. When using the MAGMASOFT program, more time is needed for the calculation process, but more correct results can be obtained. Also, the interface and functions of this program are more advanced and more convenient. After comparing the results of the formation of shrinkage shells during casting simulation using both programs, it was found that they practically do not differ. Therefore, this model can be considered successful. Based on the obtained results, it was shown that the stage of virtual design of casting technology (before the production of castings) allows for minimizing possible miscalculations and errors that inevitably occur in the development process, reducing financial and time costs, increasing efficiency, competitiveness, quality and reliability of products.
