The influence of holding pressure on powder distribution in PIM technology
Original language description
The powder injection molding technology (PIM) is very sensitive process where the resulting quality of the part is defined by quality reached in each step of the whole process. This quality of the part is then usually possible to see first at the end ofthe process while the fault could occur already at the beginning, often during injection-molding. Therefore is necessary to find the way how to evaluate the injection-molding process and discover the fault earlier. Very often cause of the defects is the?phase separation? (inhomogeneity in powder distribution), which occurs during injection-molding and can be also influenced by the holding pressure. This paper is then focused on evaluation of the powder distribution in the ?green part? stage with the new method based on density measuring. Measurements were done with using different values of holding pressure.
