Polycrystalline diamond (PCD) core integrally bonded to a tungsten-carbide-supported ring which in turn enhances strength of die blanks.
Descriptions of Tungsten Carbide Supported Diamond Die Blanks:
Tungsten carbide supported diamond die blanks is manufactured by means of cold pressing insertion. Polycrystalline diamond (PCD) core integrally bonded to a tungsten-carbide-supported ring which in turn enhances strength of die blanks. All blanks contain metal catalyst in PCD structure. These features give the products stronger ability to withstand wire drawing with high intensity.
Features of Tungsten Carbide Supported Diamond Die Blanks:
* Special design of taper shape makes the tungsten carbide supported diamond die blanks easy to distinguish between the inlet and the outlet.
* The alloy ring can protect the material to enable it to bear larger impact.
* The large external diameter of the alloy ring can provide enough centripetal bearing force for diamond&enough resisting force against wire drawing.
