JCB diamond wire drawing dies are divided into three major series for users to choose from: single crystal diamond wire drawing dies, PCD wire drawing dies, and CVD wire drawing dies. JCB diamond wire drawing dies exhibit strong wear resistance and an exceptionally long service life. They are widely used for drawing high-precision wires for electronic devices, radar, television, instruments, aerospace, and other applications, as well as common wires such as tungsten wire, molybdenum wire, stainless steel wire, electrical cable wire, and various alloy wires.
Our company's diamond wire drawing die materials are divided into three major series for users to choose from: single crystal diamond wire drawing dies, PCD wire drawing dies, and CVD wire drawing dies. They are suitable for drawing various types of soft wires, such as gold, silver, platinum, brass, phosphor bronze, aluminum, etc., as well as hard wires, such as iron wire, stainless steel wire, nickel wire, chromium wire, molybdenum wire, tungsten wire, copper-clad steel wire, etc.
| name | advantage | Scope of application |
| Single Crystal Diamond Wire Drawing Die | High finish, high hardness, good wear resistance, high precision, can ensure the surface finish and accuracy of the wire in the long drawing process. | Suitable for drawing all kinds of soft and hard wires with a straight diameter of 0.0015-1.5mm. |
| PCD Wire Drawing Dies | Isotropic, processing does not have to consider its orientation, and has better toughness, high hardness, good wear resistance, high precision, high finish, in the long drawing process can ensure the surface finish and accuracy of the wire. | Suitable for drawing all kinds of soft and hard wire with diameter 0.05-30mm. |
| CVD Wire Drawing Dies | Polycrystalline structure of pure diamond, high hardness, good wear resistance, integrated the advantages of polycrystalline and single crystal diamond wire drawing die, die hole accuracy and luminosity, stability are close to the natural diamond wire drawing die, high finish, high temperature resistance, high precision, in the long drawing process can ensure the surface finish and accuracy of the wire. | Suitable for drawing all kinds of soft and hard wire with diameter of 0.05-1.0mm, especially suitable for high temperature drawing. |
