Abstract
AbstractThe issue of the expediency of metal mold casting techniques in small-scale manufacture of castings has been studied considering the modern production capabilities of 3D simulation and computer numerical control (CNC) machines. The results of a statistical analysis of the activities of enterprises located in the Moscow and Ural regions of the Russian Federation are provided. These results show that among all the metal mold casting techniques, chill casting is most actively used. A method for comparative estimating the costs of castings manufactured by different techniques has been developed, depending on the casting production volume and the life of the process equipment applied. The method allows calculating the cost of castings manufactured by different techniques based on publicly available information. An example of using the method developed is given for two engineering iron castings obtained by two casting techniques in chill molds and expendable no-bake casting ones. The cost of engineering iron castings obtained using two casting techniques in chill molds and expendable no-bake casting ones has been determined for the production volume within 1 to 1000 pieces. The results obtained allow concluding on the possibility of using chill casting in small-scale manufacture of engineering iron castings.Keywords3D printed mold patternsSand castingChill castingChill moldCNC machine
