NO.1 Diamond wire drawing die core

Metal wire drawing, especially hard metal or hard alloy drawing requires drawing die core with high hardness, high wear resistance, to ensure that the wire size accuracy and finish, and improve the working life of drawing die. Diamond possesses high hardness, high thermal conductivity, low coefficient of friction, low coefficient of thermal expansion, good chemical stability and other excellent performances, as the wire and pipe of the ideal drawing core materials.

NO.2 Basic applications

Diamond wire drawing die core effectively improves production efficiency, cost savings, high wear ratio, dimensional accuracy, high finish, and has a comprehensive adaptability, widely used in electronic devices, radar, television, instrumentation and aerospace high precision wire materials and commonly used in tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire, and a variety of alloy wires.

No.3 Our products——CVD Industrial Synthetic Diamond Applied on Wire Drawing Die Core

Chemical Vapor Deposition (CVD) synthetic diamond is made by Chemical Vapor Deposition process, It is polycrystalline structure in translucent light yellow green. It is recommended to be used as high quality wire drawing die, such as: drawing/pulling soft wires with diameter less than 1.5 mm like copper wire, aluminum wire, etc. and hard wires with diameter less than 1.0 mm like stainless steel wire, tungsten wire, molybdenum wire, etc. 

Features: Does not contain any additives, stable quality, high hardness, good wear resistance, difficult to change the core diameter, drawing long lifespan, high finish, with excellent thermal properties and high temperature oxidation resistance, good thermal stability, suitable for wire hot pull, cold pull and high speed drawing, a collection of the advantages of polycrystalline and single crystal diamond wire drawing die core.

NO.4 The advantages of CVD industrial synthetic diamond wire drawing die core

Compared with the natural diamond wire drawing die core, in addition to the cost greatly reduced, the CVD diamond unique isotropic characteristics make the drawing core diameter not easy to change, greatly extend the working life, effectively improve the quality of products and production efficiency;And compared with PCD wire drawing die core, due to the CVD diamond wire drawing die core is pure polycrystalline structure, the core material without any metal additives, drawing finish and lifespan are better than PCD, can draw tungsten, molybdenum, copper, aluminum, stainless steel wires and other materials with a diameter of less than 0.05mm, which cannot be produced by PCD. CVD Diamonds are ideal substitutes for natural diamonds and PCD.
