The wire drawing die is widely used, such as electronic devices, High-precision wires used in radar, television, instrumentation and aerospace, as well as commonly used tungsten wires, molybdenum wires, stainless steel wires, wire and cable wires, and various alloy wires are all drawn with diamond wire drawing dies. Natural diamond is used as the raw material, which has strong wear resistance and extremely long service life. The production process of wire drawing die inserts includes several process steps such as pressing die, drawing die and turning. The drawing die is a kind of metal wire that passes through a mold to gradually reach the size that people need from thick to thin. This special mold is the drawing die. The core of the drawing die is generally made of natural diamonds, artificial diamonds (man-made diamonds) There are GE, PCD, synthetic materials, etc.). Copper wire drawing dies are flexible wire drawing dies. There are hard wire drawing dies, such as tungsten wire, etc. The angle of the compression zone of tungsten wire drawing dies is relatively small, generally 12- 14-degree wire drawing dies include diamond wire drawing dies, cemented carbide wire drawing dies, plastic wire drawing dies and so on.
