Die Pressing

Stage 1
Ceramic powder is contained within a hopper and fed over a die cavity by a 'shoe'

Powder will flow under gravity and fill the die cavity

Stage 2
The shoe will retract and the top punch of the die will come down and compress the powder within the cavity to form a 'dense' powder compact

Stage 3
The top punch will retract, and then the lower punch will rise and eject the ceramic compact. The powder shoe will then start the cycle again and in doing so, push the powder compact off the press to a holding area
