1. The Metallurgical Aspects of Machinability in Prehardened Mould Steels
Abstract : High economical efficiency obtained by utilizing prehardened mould steels in plastic mould making has increased the usage of these types of steels to a great extent. Generally, prehardened mould steels are applied for large moulds and moulds for moderate production runs, and one of the advantages of using this type of steel is that no heat treatment is necessary for putting the mould in use.

4. Polishability of tool steels : Characterisation of high gloss polished tool steels
Abstract : The manufacturing of plastic components, like a majority of other mass produced discrete parts, require well designed dies and moulds. Complex geometries and increasing demands on final surface appearance, which is strongly connected to the quality impression, are pushing for high demands on mould-makers and polishers as well as steel producers.

5. Appearance characterisation of textured polymeric surfaces
Abstract : Appearance demands for industrial products are generally increasing since they are closely related to the overall quality impression. Consequently, there is a need to define appearance through its main descriptors, which are gloss, colour and surface texture, as well as the relations between them. READ MORE
