Diamond wire drawing die blanks |
|
|

|
|

|
The diamond wire drawing die blanks are
polycrystalline diamond (PCD) products made under
high temperature and ultra-high pressure.
The components of PCD are diamond powder and a metal
catalyst (cobalt) sintered together. They have not only
high wear resistance, hardness and thermal
conductivity but also high mechanical strength and
tenacity.
Our diamond die blanks are a unique product
to draw a wide range of metals such as copper,
aluminium, nickel, nickel-chrome, steel, staniless
steel and special alloys.
We have two series of diamond wire drawing die blanks:
DW and TDW.
DW series are self-supported die blanks in two different
types: DWH (Hexagonal) and DWR (Round).
These blanks
are suitable for all kinds of wire drawing applications and
where a cost cutting is required.
TDW series are tungsten carbide supported die blanks
with a polycrystalline diamond core integrally bonded to
a tungsten carbide ring.
This feature makes it suitable for
drawing with high intensity.
DW and TDW are available in 5 different grades of grain
size: 3, 5, 10, 25, 50 micron. |
