.... Clearance between die walls and rams with all die styles creates flash, leading to localized tool wear and increased flash thickness, which limits edge sharpness. Thus, lower compaction pressure is desired to reduce tool wear and maintenance. Green density can be reduced to lower compaction pressure...
