Drawing die is a very important mold for drawing various kinds of wire rod manufacturers (such as wire and cable factory, steel wire factory, welding wire and wire factory, etc.). 

The wire drawing die has a wide range of applications, and is mainly used for drawing straight, difficult-to-machine objects such as bars, wires, wires, pipes, etc., and is suitable for 

drawing processing of steel, copper, tungsten, equal metal and alloy materials.

When drawing copper wire of the same diameter, the service life of polycrystalline diamond die is 300-500 times of the life of cemented carbide die and 80-100 times of drawing of 

nickel wire. When drawing molybdenum wire, its life is only hard. The life of the alloy mold is 50-80 times, and when the carbon steel is drawn, the life of the polycrystalline diamond 

mold is 20-60 times that of the cemented carbide mold. In addition to the commonly used wire and cable drawing die, polycrystalline diamond wire moulds also include enameled wire 

molds for motors, electrical appliances, transformers, etc., precision inner lead molds such as integrated circuits.
