摘要：

Micro-metal injection moulding process technology is one of the key technologies to satisfy the increasing demands for smaller parts associated to miniaturisation and fictionalisation in different application fields. The process combines the shape-making capability of polymer by hot embossing with sintering technology to produce complex, high density metal parts with outstanding properties. The present work focussed on elaboration and characterisation of feedstock based on 316L stainless steel powders for micro-powder embossing process. In this paper, the rheological specifications of the binder and the feedstock were observed by means of capillary rheometry. Thermogravimetric analysis was carried out on feedstock in order to understand decomposition behaviour of the binder components. The effects of sintering temperature on the dimensional stability, and particularly hardness of sintered components, were investigated. The results show that the feedstock can be used for the manufacturing of the micro-fluidic die mould cavities with a low roughness, proper dimensions and good shape retention.
