Untersuchungen am IKV haben gezeigt, dass sich im Vergleich zu gefrästen und polierten Werkzeugoberflächen mit erodierten Werkzeugoberflächen eine Fließwegverlängerung erzielen lässt. This is attributed to the incomplete moulding of the eroded, crater-shaped mould surface, which creates micro air pockets between the melt and the mould surface. The air pockets have an insulating effect at the interface and inhibit heat transfer from the melt to the mould. The influence of eroded mould surfaces on the flow behaviour of thermoplastics will therefore be further analysed in the project „Analysis of function-oriented surfaces of injection moulding cavities manufactured by electrical discharge machining“ (AOS).
