Abstract

Deposition of powders in confined spaces (e.g., dies) is the required first step in manufacturing pressed parts. The quality of the pressed parts is adversely affected by the non-uniform pre-compaction spatial fill density of the particulate in the die. To determine in-situ fill density distribution, a real-time spatial cumulative mass distribution tester incorporating multiple load cells has been designed and fabricated. Preliminary experimental analysis has been carried out for different treatments (die cross-section, rate of die fill, method of die fill, and aspect ratio) for one powder. Data interpretation leads to the inference that both die shape and rate of die filling may be significant factors affecting spatial fill-density distribution. Work is in progress on repetition of identical treatments for five different powders.
