Abstract in different language: This article deals with the influence of the gate position on the final properties of a plastic product after the injection moulding process. Parameters such as temperature, fibre orientation and filling velocity are evaluated. The importance of the internal fibre orientation on the mechanical properties is also described. Advanced virtual mould-flow analysis is used for this research. A simple brick from Polybutylene Terephthalate (PBT) with 30% of short glass fibres is chosen as the reference part. A virtual model of PBT is described in depth in this article. An injection process with the same initial parameters was used for three different locations of the pin gate. This type of gate is considered because it is one of the most frequently used in the plastics industry. Different kinds of gates and their influence on filling are also briefly described. This paper shows the importance of the gate location and it also helps to understand the flow of short fibre reinforced thermoplastics inside the mould cavity. The article presents an in-depth and complex view of the issue of mould filling.
