About drawing dies

　　In metal pressure processing, the metal is forced through the mold under the action of external force, the cross-sectional area of the metal is compressed, and the tool that obtains the required cross-sectional area shape and size is called a wire drawing die.

　　Wire drawing dies have a wide range of uses, such as high-precision wires used in electronic devices, radar, television, instrumentation and aerospace, as well as commonly used tungsten wires, molybdenum wires, stainless steel wires, wires and cables, and various alloy wires. The produced diamond wire drawing die adopts natural diamond as raw material, so it 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 die for the metal wire to gradually reach the size people need from thick to thin. This special die 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 also hard wire drawing dies, such as tungsten wire. The angle of the compression zone of copper wire drawing dies is generally 16-18 degrees. The diameter length is 30-40% and the angle of the compression zone of the tungsten wire drawing die is relatively small, generally 12-14 degrees, and the fixed line length is 60-70%.
