It is difficult to imagine if there is no wire drawing die, metal drawing process will be how cumbersome. With the wire drawing die, metal wire drawing process is very easy to be very simple, and a lot of processing is not a problem. Drawing die in general there are 6 kinds of different materials, with the process and processing of different metals, will choose a suitable drawing die. Natural diamond wire drawing die has a good color, and the hardness is very enough, and the work of natural diamond wire drawing die can automatically choose a better direction of grinding. But the natural diamond wire drawing die has a fatal shortcoming is the cost is high.
Artificial polycrystalline diamond wire drawing die hardness, gloss, and also resistant to corrosion, abrasion resistance, so, with the emergence of artificial polycrystalline diamond wire drawing die, has also been more applications. The material quality and hardness of alloy steel wire drawing die are inferior products, but the price is low, the operation is simple, so it is still used in some wire drawing. Carbide drawing die is generally made of tungsten. The tungsten carbide material wire drawing die anti wear ability, is also resistant to corrosion, and between the poor adhesion, resulting in small friction force, so the use of the materials can be easily save energy, and because the cost is within the acceptable range, so hard alloy wire drawing die is also applied to the many fields.
Ceramic wire drawing die in addition to superior corrosion resistance, the chemical stability is beyond doubt, will not occur under high temperature conditions and other substances chemical reaction, so the popularity is also good. Coated wire drawing die and the advantages of several drawing die in front are almost, the disadvantage is that the coating is easy to paint off, the appearance will become dark. There are so many different materials made of wire drawing die is also from the other side of the wire drawing die in the wire drawing industry in the application of how widely, its importance is beyond doubt.
