ABSTRACT:
The present invention is a method and apparatus for the production of compacted powder elements. More specifically, the present invention is directed to the improvement of tooling for powder compaction equipment, and the processes for making such tooling. The improvement comprises the use of a ceramic tip or similar component in high wear areas of the tooling, particularly center pins. Moreover, the use of such ceramic components enables reworking and replacement of the worn tool component.
