    In this article, the objects of research are 40 pieces sleeves made from aluminum alloy 6080 and results were obtained from the measurement of the observed sign of inner cylindrical surface runout relative to the external one. The graphical visualizations of the analyzed data were made. A comparison is made between the amount of error obtained by two setting methods on a CNC lathe- in a universal self-centering chuck and between centers.

    In the article, experimental results according to ASTM D6992 standard test method for accelerated tensile creep of plastic films were investigated and analyzed. A regression model was created based on the obtained results. Real and theoretical data were compared. In order to determine deviations of the model and what is the reliability of the theoretical data.

    In this article, the residual strength of PE geocells after accelerated aging is experimentally investigated. The characteristic is of key importance for the application of geocells, as it is related to their service life.The durability test is defined as essential in the applications standards of the product-EN 13 255:2016,EN 13 251:2016.

  • MATHEMATICAL MODELLING OF TECHNOLOGICAL PROCESSES AND SYSTEMS

    Simulation study of the effect of coolant temperature on injection molding quality

    As plastic products shrink during cooling, so knowledge of shrinkage factor for different materials is required. The main objective of the study is to examine the influence of mold cooling process on subsequent deformation of finished part. To achieve the goal, simulations were carried out at different temperatures of the cooling agent. Statistical processing was performed and a regression model was derived describing the relationship between temperature, time and deformation during cooling.
