The Experimental and Numerical Analysis of Stress as a Tool for Optimizing the Selected Structural Components of an Injection Device

Abstract

The improvement of the main monitored technical parameters of the production devices is connected with the optimization of the individual structural components and construction nodes of these devices. Mainly those critical structural nodes of the devices that have a significant impact on the quality of the products manufactured by this device and its service life are studied. This paper briefly presents the results of experimental and numerical analysis of stresses and strains of selected structural components of the injection device, such as the connecting and guiding columns and the adjustable push plate. The relevant analyses of stresses and strains have been connected with the performance of a series of experimental and computer simulations. The results of these simulations then became an important basis for further optimization of selected structural parts of the injection device.
