Synthetic diamond is usually prepared by a high temperature and high pressure sintering method, and also by a crystal growth method. Synthetic diamonds include synthetic polycrystalline diamond and synthetic single crystal diamond.

Since the first production of diamond powder, it has been continuously developed to produce diamond compact blocks. This synthetic diamond crystal orientation is irregular, that is, uniform high strength and wear resistance in all directions. Therefore, the molding of the material is simpler than the natural diamond in the process, and during the drawing process of the wire, the umbilical damage of the mold is non-directional, that is, the wear of the die hole is relatively uniform and concentric. Compared with the natural diamond mold, the synthetic diamond mold can draw the wire of the saddle diameter, but due to its polycrystalline structure, it is impossible to provide a good mirror polishing finish like natural diamond, so it is still less than natural diamond in terms of high precision. mold. Nevertheless, with the advent of various high-precision polishing equipment and the successful research of fine-grained synthetic diamond production process, the problem of man-made diamond mold hole smoothness is expected to be solved, and the production of extremely fine-grained artificial barrier rock blanks is resistant. The temperature can reach 1100 ° C, and the natural diamond mold can get the finish. It can be used for the drawing of filaments. "The synthetic diamond mold is widely used in the copper wire and steel wire industry. Especially when the wire diameter is increased, the natural diamond mold is not as good as the fine crystal and medium crystal polytype mold, for example, the tungsten wire diameter is 0. 35~0.60ram. When the drawing temperature is above 700 °C, the natural diamond mold can not be used normally. The use of polycrystalline mold is better.

At present, synthetic polycrystalline diamond has become a material that fills the gap between tungsten carbide and natural diamond, and its mold has a long service life. Compared with the tungsten carbide mold, the polycrystalline mold has a 120-fold increase in service life in aluminum wire drawing and a 50-fold increase in molybdenum wire drawing. In the drawing of tungsten wire, there is also a good application before, at the same time, because it is easy to mold. The price is also relatively cheap, so that the synthetic diamond mold has a tendency to replace the tungsten carbide mold and the natural diamond mold in the modern drawing industry.
