Natural Diamond

As a kind of natural cystal formed in the earth crust under ultra high stress and temperature (about 1200℃), natural diamond is the hardest material in the world.

Natural diamond dies have long life time. In processes of drawing wires, they can work in very fast drawing steep but do not break easily. Moreover, the hole of diamond dies are very smooth , so they are suitable for drawing many kinds of non ferrous and ferrous metal ,especially for wires that request good surface.
With 20 years’ experience in manufaturing diamond dies, besides diamond dies with superior quality, we can also provide a whole set of wire drawing solutions including die matching, recutting and so on.

Inner Geometry

Inner geometry of natural diamond 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.
