Advantages The mould for polycrystalline wire drawing dies and tube drawing is made of high quality mould core,which has the advantages of uniform texture,strong wear resistance,high finish,high precision and long service life,The surface finish and accuracy of wire rod can be ensured in the long-time drawing process.

Polycrystalline diamond(PCD) sintered under high temperature and high press together with binder alloy is used.
Diamond Wire Drawing dies of high and consistent quality covering small to large diameters exhibit outstanding performance in larger size areas than single crystal diamond drawing dies.
There are some factors to consider when specifying a PCD wire drawing dies,PCD insert size, PCD grain size,casing size and hole geometry.
This kind of PCD wire drawing dies based on cobalt,is improved in hardness and density with more even degrees and more reasonable molecule structure,reducing particle chipping off and roughness.The fine grain supports to provide higher surface of drawing wire.

Polycrystalline Diamond Wire Drawing Dies

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.

Cobalt-Based Diamond Drawing Dies

Factory Price Diamond Wire Drawing Dies;Cobalt-based PCD Wire Drawing Dies With Long Drawing Life

Polycrystalline Diamond (PCD) is a kind of artificially sintered diamond,which can be used in all wet drawing and dry drawing processes,polycrystalline diamond high temperature pressing and alloy bond sintering.There are three types of polycrystalline diamond embryo: non reinforced ring type, reinforced ring type and heat stable setting type.
Polycrystalline Diamond Wire Drawing Die is the longest die life of all materials,which can provide the highest production efficiency and reduce downtime.It is suitable for all applications from large drawing to ultra-fine drawing,with predictable wire surface quality.
With the free arrangement of diamond crystals,the wire rod can still keep good roundness even under the condition of severe wear of die,and the size of blank can be guaranteed,and the expected maximum reaming size can be obtained.It can be used in all wet drawing and dry drawing processes.It is mainly used in larger size, more demanding wear requirements,but less important surface finish.

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.
