JCB diamond wire drawing die is divided into single crystal diamond wire drawing die, PCD wire drawing die and CVD wire drawing die three series for users to choose. JCB diamond wire drawing die has strong wear resistance and extremely high service life. Diamond wire drawing die is widely used, such as drawing electronic devices, radar, television, instruments and aerospace used in high-precision wire and commonly used tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire and various alloy wire.
Our company's diamond wire drawing die is divided into single crystal diamond wire drawing die, PCD wire drawing die and CVD wire drawing die three series for users to choose. Suitable for drawing all kinds of flexible wire, such as: gold, silver, platinum, brass, phosphor bronze, aluminum, etc. And hard wire, such as: iron wire, stainless steel wire, nickel wire, chromium wire, molybdenum wire, tungsten wire, copper clad steel wire.
name | advantage | Scope of application |
Single crystal 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 drawing die | 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 die | 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. |
