PCD dies- Co base have two different die blank: Self-Supported Die Blanks
& Tungsten Carbide Supported Die Blanks.
Dies with tungsten carbide supported eie blanks can withstand greater pull, more used in the manufacture of large aperture mold embryo, pulling a thicker diameter of wire - 3mm or more wire is recommended with carbide ring.

What is a Drawing Die

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

Wire drawing dies have a wide range of uses, such as high-precision wires used in electronic devices, radars, televisions, instruments 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. The 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, drawing and turning.

The wire drawing die is a kind of mould that the metal wire pass through to reach the size that people need from thick to thin gradually. This special mold is the wire drawing die. The core of the wire drawing die is generally made of natural diamonds, artificial diamonds (man-made diamonds, such as GE, PCD, synthetic materials, etc.). Copper wire drawing dies are for drawing soft wires. There are dies also for drawing hard wires, like tungsten wire, etc. The angle of the dies for drawing tungsten wire is relatively small, generally 12- 14 degrees.

Wire drawing dies include diamond wire drawing dies, tungsten carbide wire drawing dies, plastic wire drawing dies, etc.
