Nano Wire Drawing Dies

Nano coating mold detailed introduction
This mold is also called "stranded wire compression mold", with a winch, multiple strands of metal wires are twisted and compressed into qualified wires and cables. The mold recommends the use of nano-diamond composite coating.
The stranded wire compression mold with nano-diamond composite coating has the following characteristics and advantages:
The manufacturing characteristics of the nano-diamond composite coated stranded wire compression mold are:
1)With nano-diamond composite coating
2)Pass type optimization
3)Computer-aided detection
Therefore, the application characteristics of the mold itself are:
1)Mold reference life: 500～1000 kilometers of conductor can be stranded continuously(because of nano-diamond composite coating and optimized pass)
The working life of the original cemented carbide compacting die is only 20-30 kilometers.
2)Change in aperture when mold is scrapped:0.00 mm, free of mold repair(because of nano-diamond composite coating)
The finish of the original cemented carbide compression mold gradually deteriorates in use, and it needs to be polished many times, and the hole diameter is enlarged. When the hole diameter is out of tolerance, it is scrapped.
3)The working surface has a high finish and remains unchanged(because of the nano-diamond composite coating)

The finish of the original cemented carbide compression mold gradually deteriorates in use, and it needs to be polished many times.
4)High dimensional accuracy(because of computer-aided inspection)
Therefore, the direct benefits to users are as follows:
1)Improve production efficiency(because of long life and constant hole diameter)
The use of nano-diamond composite coating compression molds can greatly increase the output during its full life cycle, reduce the number of shutdown inspections and mold changes, the single-filament breakage rate is significantly reduced, the labor intensity of the workers is reduced, and the production efficiency is significantly improved, which can bring great economic benefits to application enterprises every year.
2)Improve the withstand voltage level of the cable(because the hole diameter remains unchanged)
Using nano-diamond composite coating compression mold, the stability of the cable cross-section is very good, the conductor cross-section remains unchanged for a long distance, which is conducive to the stable control of the thickness of the semiconductor shielding layer and the insulating layer, and it is also beneficial to improve the voltage resistance of the cable.

3)Save copper(aluminum)materials, semiconductor materials and insulating materials(because the aperture remains unchanged)
The use of nano-diamond composite coating compression mold, because the hole diameter is unchanged, compared with the traditional mold, the hole diameter is continuously expanded, and the same length of the cable can be stranded, which can save 1 to 2%of the weight of metal materials; the mold hole diameter stability band The stability of the cable compression coefficient can also save semiconductor materials and insulating materials.
4)Significantly improve the partial discharge performance of the cable(because the working surface is smooth)
The use of nano-diamond composite coating compaction mold significantly improves the surface finish and precision of the round conductor, the surface is smooth, the brightness is good, the degree of copper oxidation is reduced, and the outer diameter of the product is uniform, which is conducive to the stability of the core resistance, and the core surface is mirror-like The brightness of the cable eliminates burrs and sharp corners on the surface of the cable conductor, which can improve the uniformity of the electric field distribution in the future operation of the cable, which is beneficial to improve the insulation level of the cable(especially the improvement of the cable partial discharge level),thereby extending the use of the cable The service life has fundamentally improved the quality and qualification rate of cable products.
5)Energy saving(because of the high finish of the working surface)
Using the nano-diamond composite coating compaction mold, because the mold work surface smoothness is improved, the friction between the mold and the stranded wire is reduced, so that the cable of the same length is drawn, which saves the power consumption of the machine compared with the traditional mold.
