Pressing And Sintering Of Powder Parts

Powder particles can become stuck within this clearance, causing problems with the proper movement of machinery. In order to prevent powder particles from becoming lodged within this gap, clearance is designed to be extremely low. Clearance values between punch and die, used for powder pressing, are typically less than .001 inch.
