INQUIRY

PCD（Polycrystalline Diamond）is synthetic diamond product. The carbon molecule forms PCD under ultra high temperature and press. Strong bond between diamond particle make PCD have higher abrasive resistance,hardness as well as good thermal conductivity. Moreover, PCD can be easily processed to dies with wider range of diameter ,long life time and high economic benefits.

Inner geometry

Inner geometry of the PCD dies have“Entrance,approaching,reduction,bearing length and exit part”.
a. Entrance: For wire entering,prevent the dies from wire hurting.
b. Approaching: Make the wire to be accessible for lubricant.
c. Reduction : The wire begins to transform from original diameter to smaller diameter.
d. Bearing: The wire achieves to the final diameter.

e. Back Relief: Prevent the final wire surface from scratching.

f. Exit: Wire exiting.
