Abstract

- It is well known that high quality tool steels, i.e. steels possessing low contents of defect structures, and the adoption of well developed polishing techniques are required to get satisfactory mould surfaces for plastic forming. However, there is still a lack of knowledge concerning how different defect structures on mould surfaces affect final plastic components, and how tool steel surfaces can be measured and analysed in convenient ways.Based on non-contact 3D-surface texture analysis, three test moulds and corresponding injection moulded plastic plaques were characterised with the objective to study how defect structures on the mould surfaces were transferred into the final plastic components.Surface structures, remaining scratches and to a certain extent pin-holes originated from the mould surface were all detected on the surface of the plastic components. However, more extensive studies need to be performed in order to understand why different defect structures on tool steels occur, how they can be avoided and, for different plastic products, which the critical limits are (in terms of amount, shape and size of the defects).
