Abstract Aircraft and aerospace industry as well as medical and automotive engineering continuously require to develop smaller and lighter system components. Therefore it is not only important to be able to produce micro parts but also toprovide properties for dimension and design. However, the properties known fromthe macro range can not be assigned offhand to the micro range. The miniaturization in geometry causes deviant production conditions of injection moulding process and consequently changes inner characteristics, which in turn induces different mechanical properties.
