PCD Wire Die, polycrystalline diamond dies, Wire Drawing Dies
1. Description:
PCD(PolycrystalMne Diamond) is a kind of synthetic diamonds. The carbon molecule forms PCD under ultra high temperature and press. Strong bond between diamond particles make PCD have higher abrasive resistance,hardness as well as good thermal conductivity.
PCD wire drawing die is a normal wire tool made by PCD blanks. When pass through a group of PCD dies, the wire gradually deforms then becomes thiner and thiner, finally comes to target size.
