Nano Coated Diamond Wire Drawing Dies

The nano-diamond coating drawing die is made of cemented carbide (WC-Co) as the substrate, and the surface of the inner hole is coated with a micro-nano-scale diamond composite coating by chemical vapour deposition (CVD), which is ground and polished.

Product Description

Wire Drawing Dies

The Advantages of Nano-coated drawing die.

1. Targeted pre-treatment process: make the coating and substrate closely combined.

2. The bottom micron diamond coating has excellent wear resistance.

3. The surface nano diamond coating provides an excellent surface finish and low friction coefficient.

4. Computer simulation and optimization of hole design: high dimensional accuracy, uniform stress on the wire rod, saving raw materials.

5. There is no change in the diameter of the die from use to scrap, reducing the times of downtime inspection and drawing die change and improving production efficiency.

6. Wider diameter range, service life is 5 to 10 times that of tungsten carbide.

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.
