Abstract

In micro- and thin-wall injection moulding the process conditions affect the developed internal structures and thus the resulting part properties, e.g., wear behaviour. In this paper a dynamic mould tempering was used to affect the local morphology development and the resulting wear. Investigations with a pin on disc measurement on semi crystalline polymers reveal a distinct layer-dependent tribological behaviour of the injection moulded micro parts. Increased mould temperatures during injection moulding favour the morphological structure and the resulting part properties.
