Analysis of Feedstocks Separation during Powder Injection Molding

Popis výsledku v původním jazyce

Separation of metal and ceramic powder particles from polymeric binder during powder injection molding (PIM) is the most frequent reason for quality failure of final sintered parts. Methods analysing the separation reported so far (X-ray, tomography, SEM) are limited to a qualitative description of this phenomenon. In this paper, Energy Dispersive Spectroscopy (EDS) of SEM of the testing samples derived from the specially designed injection mold are analysed with analytical computation approach providing quantitative, so called variability parameter, which depicts the susceptibility of the particular PIM feedstocks to the separation in the scale from 0 to 100 %. Then, non-destructive analysis of surface quality of the sintered parts determined with a contactless scanner with a First Interface Detection testing mode combined with suitable statistical methods allows comparing the tendency to the separation as a function of material composition and/or processing parameters.
