Metal Injection Molding Technology: Expectations and Limitations

Popis výsledku v původním jazyce

Metal Injection Molding (MIM) technology is a state-of-art process for making metallic items of various uses in automotive, computer and other industries. This method allows the large-number production of small metallic parts of complex shapes with reduced cost and increased efficiency. It combines the flexibility and mass production of injection molding with the efficient use of materials employed in powder metallurgy. While at the beginning the research dealt mainly with tailoring suitable polymeric binders to the particular powder and desired application, at present it concentrates to the sophisticated treatment of the critical points of the MIM process. One of such points is injection molding, which depends on a primarily viscous flow of the mixture into the die cavity. In this paper we concentrate on the flow disturbances occurring during shear flow of highly concentrated (up to 55 vol.%) hard-metal carbide compounds, showing the possibilities of their reduction or/and full elimin
