ND wire drawing dies is mainly used for drawing fine and ultra-fine wires,or it is widely used in applications requiring excellent wire surface finish and good heat dissipation performance.
Advantages
Natural diamond drawing die is made of high quality die core,which has the advantages of uniform texture,strong wear resistance,high finish,high precision and long service life.
Natural diamonds (nd) are carefully selected,no impurities,no cracks,high hardness and wear resistance to ensure a long service life of the mold.
Natural diamond (nd) is formed naturally in the earth's crust under high temperature and high pressure.It is the most hard material in known materials.Due to its extremely rigid lattice structure,impurities such as boron or nitrogen may be infiltrated into the formation process.
Natural diamond is the material with the best surface finish of all materials.Its high hardness and wear resistance ensure the service life of the die.Among all materials,the thermal conductivity is the highest.It can be used in high temperature processing process.It can withstand temperature up to 1700 degrees.It is easy to debug and smooth in the drawing process.

α(ss)Entrance
The inlet area is polished so that the drawing fluid can circulate smoothly
α(sp)Approach
The lubrication area is finely polished, so that the wire can be easily excessive
α(rs)Reduction
The working area can reduce the drawing force, and the change-point contact is face-to-face angle drawing, which reduces friction and die wear. The deformed structure is more reasonable and stable. The upper line can be drawn smoothly when the incoming line becomes thicker or thinner.
d(k)Bearing
The fixed warp area can ensure the precise diameter, smoothness and out-of-roundness of the wire for a long time.
α(so)Back Relief
The safety angle can ensure that the wire is drawn without scratches, and the life expectancy tends to be longer.
α(sw)Exit
The deepening of the outlet can greatly support the tensile stress of the outlet.
Wire drawing is done by passing the metal wire through the hole of the wire drawing die, and applying a pulling force to the wire at the exit side of the die. The wire is contracted and squeezed in the die cavity and gradually becomes thinner, and its speed increases near the exit of the die hole. Since the volume of the wire is constant, the decrease in cross section makes it stretched. In the center, there is a hole of a certain shape, such as round, square, octagonal or other special shapes. When the metal is pulled through the die hole, the size becomes smaller and even the shape changes.
