| Popis: |
Advancement of human civilization demands small and multiple featured devices. Micro-Powder Injection Moulding (µ-PIM) is able to contribute effectively to the present need. Here, a wax-based binder and an alumina feedstock are thermally and rheologically characterized to establish the µ-PIM process. The alumina powder is characterized by means of shape, size and distribution of particles. The thermal analysis using DSC (Differential Scanning Calorimetry) and TG (Thermogravimetry) shows that the binder system gets completely melted at a temperature above 92 °C and completely degraded at a temperature above 478 °C. Specific heat and latent heat of solidification are calculated from the DSC results. The thermal conductivity of the binder system is measured covering the whole solidification range. A shear-thinning behaviour is observed in rheology analysis of the binder as well as of the feedstock. A modified-Cross model is used to fit the experimental data of the rheology analysis. At last, micro-channels are successfully injected, debound and sintered with the said feedstock. However, these characterized data can be used for the simulation of the injection stage for product optimization. |
