                                       Diamond PCD Wire Drawing Die

——Self-Supported and Tungsten Carbide Supported Blanks for Wire Drawing Applications.

Diamond/PCD wire drawing die blanks from our Company have the advantages of longer service life, and PCD die blanks are polished on one side or on both sides. As wire drawing die has evener and finer micro structure nearly without abnormal nucleation, so when drawing metal wires, they embody higher surface finish and brightness. Isotropic material on the view of macroscopic, so omnidirectional abrasion wearing during processing and usage. Our diamond PCD wire drawing die has advantages in high hardness, good abrasive resistance, high strength, good thermal conductivity, low friction coefficient with nonferrous metal, good anti-cohesive property, erosion resistance and chemical durability. so our diamond PCD wire drawing die is widely used in mechnical processing and especially important in ultraprecision machining.

Our diamond wire drawing die blanks are polycrystalline diamond (PCD) products made under ultra-high temperature and ultra-high pressure, they are suitable for high-speed drawing of nonferrous wires such as bronze, aluminum, nickel, stainless steel and other alloy wires. We have TS diamond PCD wire drawing die, RHD diamond PCD wire drawing die, imported diamond PCD wire drawing die, CVD wire drawing die, Monocrystalline diamond wire drawing die.

Festures for embedded wire drawing die with support
1). The PCD material after various processing and measurements,it can guarantee the PCD diamond high grade quality,not like other suppliers’ products that good in appearance but the inner size is very soft
2). The special Cone design , easy to find the input and ouput side,it can realise the carbide ring to protect the PCD diamond,it can afford high shock during wire drawing process.
3). Since the embedded design,it can provide enough centripeta holding power,so when in nesting,you do not need the metal powder sintering process, just use “cold nesting” is OK.
4). We use cobalt bond and also thermostabile non-cobalt bond/matrix,or thermostabile silicon bond PCD or thermostabile CVD diamond bond ,so they can be sued for HT drawing and High Speed drawing.

                                       RHD PCD wire drawing die blanks

Our RHD diamond PCD wire drawing die has microstructure in compact and homogeneous distribution, seldom appears the situation of clustering phenomenon or diamond grain growing big abnormally. so more easy for porting and polishing, and provide high smooth finish, prolong service life of mould for drawing wire. Now the 5μm fine mesh size diamond wire drawing die is accepted by overseas customers. Abrasion ratio of wire drawing die is 0.7~1 million

                                              CVD wire drawing die blanks

CVD wire drawing die is used for cold drawing and hot drawing of all kinds of metal wire,especially for tungsten filament, molybdenum filament, steel wire, aluminium wire, brass wire.
1). It has extra high smooth finish and extra long service life.
2). Without size limitation, CVD price is much lower than monocrystalline diamond
3). Isotropy on the view of macroscopic, so omnidirectional abrasion wearing during processing and usage.
4). CVD has good abrasive resistance and high thermal resistance, which is close to high grade monocrystalline diamond, and far better than PCD material

Our diamond wire drawing die blanks have three series: RTH Series,RTR and RTY Series. In each series, there are 4 grain sizes available to choose from based on the application of wire drawing: 3 micron, 5 micron, 10 micron, and 25 micron.
RTH and RTR Series diamond wire drawing die blanks contains self-supported PCD die blanks which include the Hexagonal type and the Round type in various sizes. These blanks are suitable for all types of wire drawing applications especially where cost-cutting is required. RTY Series diamond wire drawing die blanks includes tungsten carbide supported PCD die blanks in round shape of various sizes. These products have a polycrystalline diamond core integrally bonded to a tungsten carbide support ring which in turn enhances the strength of the die blanks. These features allow the products stronger ability to withstand wire drawing with high intensity.
