Synthetic Diamond Wire Drawing Dies

Product Name	MONO Diamond Dies; SSCD Drawing Dies; SSCD Wire Drawing Dies; Single Crystal Diamond Drawing Dies; Diamond Drawing Dies
Hole Sizes	0.012-0.600(mm); 0.0005-0.0236(inch)
Applications	Used in fine and ultrafine wire sizes, or as finishing dies when wire surface quality is critical. Tungsten wire, plated-copper wire, stainless steel wire and precious metals.
Advantages	Single Crystal 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.
Synthetic Single Crystal Diamond (SSCD) is a kind of synthetic diamond with high purity,no impurity and high stability.These quality characteristics also make the material have high hardness and stable wear resistance. Most of the Synthetic Single Crystal Diamond Drawing Dies are LB type diamonds,which also contain nitrogen impurities,but exist in the form of dispersive substitution.Therefore,stable performance is the main feature of the dies. Synthetic single crystal diamond has very similar physical characteristics to natural diamond,so it can be used in all occasions where natural diamond mould can be used.

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.

MONO Dianind Wire Drawing Dies

Customized Design and Processing MONO Diamond Wire Drawing Die,Copper Aluminum Wire Drawing Monocrystalline Diamond Wire Drawing Dies

Monocrystalline Diamond (MONO) is a kind of synthetic diamond under controlled conditions.It has the characteristics of high purity,no impurity and no crack.It is mainly used in fine and ultra-fine wire drawing,or in applications requiring excellent wire surface finish and good heat dissipation performance.
It can ensure the surface finish and accuracy of wire rod and the production range of die inner diameter in the long drawing process0.05mm-0.6mm.
These quality characteristics also make the service life of the Wire Drawing Dies more stable and predictable.The advantage of this is that the diamond has a more consistent hole size than the natural diamond wire drawing dies.
Single crystal diamond has excellent heat dissipation performance,which can be used in high temperature processing technology.Its high hardness and wear resistance ensure a long service life of the die.

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.
