Supported Polycrystalline Diamond Blanks Introduction

The appearance of synthetic diamond polycrystalline wire drawing die develops a new way for the manufacture of diamond wire drawing die. In 1978, China first developed a wire drawing die made of synthetic diamond material. Through the continuous exploration and summary in recent years, there has been a new development in the wire drawing die, that is, adding a tungsten carbide ring to the periphery of the artificial polycrystalline block to strengthen the supporting polymer, thus improving its strength and impact resistance.

The so-called polycrystalline diamond is a polycrystalline diamond formed by the polymerization of many very small single crystals of diamond particles (between about 1 micron and 10 microns in diameter). The properties of this kind of polycrystalline diamond, are quite comparable to those of natural diamond , apart from its opacity. Wire drawing die made of synthetic polycrystalline diamond has good wear resistance, uniform wear of hole wall, strong impact resistance, high drawing efficiency and low price. Its price is only 1/3 of that of natural diamond drawing die. Therefore, it has been widely used in the current wire drawing die industry, gradually moving towards polycrystalline diamond dies instead of natural diamond dies.

ADVANTAGES

1.Good wear resistance,service life long ,high hardness,High wire drawing efficiency

2.Uniform wear of die hole wall,20 times higher than the cemented carbide wire drawing die

3.Strong impact resistance,apply to high speed drawing wire with good quality

4.Its absolute hardness is 150 times that of corundum and 1150 times of quartz

5.has the toughness of cemented carbide and the hardness of natural diamond
