Abstract in different language:	This paper deals with the influence of runner angles on the balanced filling of a three-cavity mould during injection moulding. The main goal of the study is to understand the influence of the angles between the runners and the balanced filling of the three individual parts. Balanced filling leads to better visual and mechanical properties of the final product. Different mould flow simulations with the same processing parameters (material, temperature, pressure and time) were performed to observe the influence of the runner angle. Polypropylene was used as the reference material in this paper. A simple cylindrical part was considered here. In essence, it seems to be a very simple situation, however before running the mould flow simulations there was no general notion of the results and their justification. The paper also raises the possibility for modifying filling behaviour by changing the runner angles and evidence that the configuration with 90 degrees between each runner is the most suitable for achieving the filling of the three parts at the same time.
