Brief Introduction
Nano Diamond Coated Dies for Cable Stranding Compacting
Nano diamond coated die, abbr, NDCD dies, which is also called CVD diamond coated dies.
They are tungsten carbide dies that have been coated with a 30 micron thick layer of nanocrystalline diamond particles. The entire interior surface of the die is coated, including the entry area which is an especially important part of the die for stranding dies. And the diamond particles in the coating are very small which is only 50 nanometers in size.
After polished, the die surface becomes extremely smooth. This low-friction, high-luster surface finish minimizes die pull for improved energy efficiency of the stranding machine, reduces fines and dust generation and creates a smoother cable surface finish.
Usage: Stranding, bunching and compacting applications in the cable industry, for example, stranded copper, stranded aluminum, etc.
Hole Diameter: 0.7mm to 80mm
Coating thickness: 0.03mm (30um)Advantages:1. Improve Dies Working Life
The service life of the nano diamond coated stranding compacting die is more than 20 times that of the tungsten carbide mold, and the conductor can be continuously twisted for 500-1500 kilometers. Carbide stranding die can only twist 20-30 kilometers of conductors.
2. Effectively Save Copper Aluminum Raw Materials
The hole diameter of the NDCD die remains the same from the time it is installed to the scrap, so it can save 1%-2% of the cost of conductor raw materials, while the hole diameter of the TC die and PCD die will become larger, and a large amount of copper and aluminum chips will be generated. The secondary connector wastes a lot of conductor material, so raw materials are wasted. Consistency of hole diameter and hole shape will lead to the stability of the compression coefficient, so it will also save semiconductor shielding materials and insulating materials.
3. Improve Production Efficiency
There is no change about the NDCD die hole from the beginning of use to the final scrapping, so there is no need to change the mold frequently for repairs, reducing the downtime for mold replacement and inspection, thereby improving production efficiency.
4. Improve the Consistency of Cable Size
Since the die is used from the beginning to the final scrap, the hole diameter does not change, and the hole shape consistency of all molds is relatively good, so the wire diameter consistency of the cable is very good. The diameter of the tungsten carbide die becomes larger and larger.
5. Improve the Surface Finish of the Cable
Because the particles on the surface of the diamond coated die reach the nanometer level, the surface finish is very high, and the mirror finish is achieved, which is always unchanged, so the surface finish of the produced cable is good and consistent, and there are no flaws and burrs.
6. Improve the Electrical Stability of the Cable and Prolong the Life of the Cable
Due to the good dimensional consistency and high surface finish, there are no flaws and burrs. Therefore, the withstand voltage level is improved, the potential stability is improved, the electric field uniformity is improved, the cable insulation level is improved, the partial discharge level of the cable is improved, and the service life of the cable is prolonged.
7. Save Electricity
Due to the nano-scale particles, extremely high surface finish and small friction coefficient, the friction between the mold and the wire is reduced, and the power consumption is greatly saved.
