In the purchase of wire drawing die, we always want to buy the product is the best, the best is no defect, so we must learn to buy a diamond die is good or bad, only will read , Can be selected to a most suitable of their own wire drawing die.

If the price from the point of view, the natural drawing die price is certainly more expensive, but it is expensive to have his reason, because this type of drawing die itself is more complicated in the processing time The kind of. Natural diamond drawing die has a very high hardness, but it is easy to cause friction, so this type of drawing die can only be used in some of the smaller diameter of the material, but its wear resistance is the best.

There is also a carbide mold, the hardness of this film is relatively low, the surface is not very rough, but its wear resistance is relatively poor, coupled with its relatively low hardness, usually not recommended to buy of. Selection of diamond drawing die is like the selection of explosion-proof electric heater, to be particularly careful, you carefully against it, it will also you a rest assured.

Blank in the drawing die cavity plastic degeneration, along the cavity surface both flow and slide, so that the cavity surface and the material between the sharp friction, resulting in wire drawing die due to wear and failure. So the wear resistance of the material is the most basic drawing, the most important one of the performance.

Hardness is the main factor affecting wear resistance. Under normal circumstances, the higher the hardness of the drawing die parts, the smaller the wear, the better the wear resistance. In addition, the wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material.
