Product Name	ND Wire Dies; ND Drawing Dies; Diamond Drawing Dies; Natural Diamond Drawing Dies; Diamond Dies; Natural Diamond Dies
Hole Sizes	0.012-2.100(mm); 0.0005-0.0827(inch)
Applications	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.

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.

The best material depends on the wire you draw and the quantity you draw. Contact us to help you choose the most economical solution and reduce the total cost of ownership of your drawing dies.

Customized Design and Processing ND Wire Drawing Die,Copper Aluminum Wire Drawing Natural Diamond Wire Drawing Dies

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.
The natural diamonds we use are strictly selected to ensure their purity.
The Natural Diamond Wire 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.It can ensure the surface finish and accuracy of wire rod and the production range of die inner diameter in the long drawing process 0.03mm-2.00mm.
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.

The Wire Drawing Die is a very important and consumable product used by various metal wire manufacturers to draw wires. The application range of wire drawing dies is very wide, mainly used for drawing straight and difficult-to-machine objects such as bars, wires, wires, pipes, etc., and generally suitable for drawing processing operations of metal and alloy materials such as steel, copper, tungsten, molybdenum, etc. . Since the cost of the wire drawing die can reach more than half of the wire drawing cost, how to reduce the consumption cost of the wire drawing die and increase its service life is the primary problem that metal wire production units urgently need to solve.
Wire Drawing Dies have a wide range of uses, such as: high-precision wires used in electronic devices, radars, televisions, instruments and aerospace, as well as commonly used tungsten wires, molybdenum wires, stainless steel wires, wire and cable wires and various alloy wires, all of which are made of diamond It is drawn by a wire drawing die. Due to the use of natural diamond as the raw material, the diamond wire drawing die has strong wear resistance and extremely long service life.
