RESEARCH REGARDING MODELING OF THE PROCESS PARAMETERS FOR MICRO-INJECTION MOULDING OF POLYMERIC MICRO-COMPOSITES

Abstract

Miniaturization represents a significant and remarkable trend in the worldwide progress of manufacturing technology. Polymeric micro-composites offer a wide range of properties that can be chosen according to the functional necessities. Polymeric micro-composites represent composites with polymeric matrix and submicron fibers with high aspect ratios or fine hollow spheres as reinforcing element. The successful development of such new micro-composites devices is highly dependent on manufacturing systems that can reliably and economically produce large quantities of micro- components. In polymer micro-manufacturing technology, software simulation tools provide useful assistance for the optimization of moulding tools, mould inserts, micro-component design, and process parameters. Research aims the simulation and optimization of injection moulding process parameters of polymeric micro-composites using advanced software tools. This paper analyze phenomena that occurring during the injection process: temperature field, injection pressure, cooling and injection cycle time. Using these results are obtained reduced part cost, increased part accuracy, improved cycle times and opportunity to achieve isotropic products made from polymeric micro-composites.
