Nowadays, there are more options available for stranded cable producers than ever before in the area of wire drawing. Currently, nano diamond coated dies are the best thing happening to wire drawing dies, manufacturers. These dies are seen to be the best for optimum bunching, stranding, and compacting for unique applications. Previously, the PCVD diamond coating technology ruled the roost when solving the adhesion problem and paved the way for a thick film diamond coating to a tungsten carbide substrate as economically the best option. It meant that nano dies for cable stranding and compacting for large diameter cables became pretty easy.
However, with demand from huge and lengthy undersea power cables and other industrial needs, PCVD diamond coating technology wasn’t economical. A completely new economical Cable compacting dies was developed that easily was accepted worldwide. Only a few companies had the technology to mass-produce these dies, and amongst them is the SZ Wire Die.

Advantages of NDCD Dies
NDCD or Nano Diamond Coated Dies are tungsten carbide dies coated with a 30-micron thick layer of nanocrystalline diamond particles. Again, the entire interior surfaces of the diamond drawing dies are coated, including the entry area. It is particularly important for stranding dies. The diamond particles in the coating are of 50 nanometers size and therefore pretty small. But when it is polished, the surface of the die becomes very smooth.
Durability is one of the chief reasons why NDCD dies are preferred over others. Again, they work effortlessly and do not cause explosion hazards when drawing aluminum wires. You will also find more efficiency with nano dies for cable bunching, and most enterprises recover their cost over a while.
In the case of pcd wire drawing dies, there are two types: cobalt-based PCD and silicone-based PCD. It is noteworthy that the cobalt-based PCD core contains a metal bond. It is very advantageous while machining is done. In sharp contrast, the silicon-based PCD core is relatively poor as there is no metal bonding like cobalt-based PCD. In such a case, the material can maintain thermal stability of 1000 degrees Celsius.
The natural diamond dies or synthetic diamond single crystal and polycrystalline synthetic diamond dies are used for specific industries, unlike the above PCD. These types of Wire Drawing Dies are used to draw low, medium, and high carbon content wires. Again, they are also pretty good for drawing aluminum, copper, and various other alloys.
More about Nano Dies
Nano dies offer a targeted pre-treatment process so that the coating and the substrate are combined properly. They are wear-resisting and have an excellent finish and low friction coefficient. Hence for nano dies for cable compacting, it is often a hassle-free process.
Nowadays, more enterprises use diamond dies for drawing wire than in earlier years as the wire size is uniform and stable. The inner hole is always bright and is self-lubricating.
