What is Nano Die
Nano die is not a kind of traditional wire drawing die. It’s made by a new method: chemical vapor deposition, short for CVD. The diamond film was coated on inner hole of tungsten carbide dies to draw wires and tubes, which will have very smooth surface because the grain size of the diamond coating is nanoscale.
Knowledge of Nano Dies
As dies made by special CVD, nano dies have their own characteristics.
Chemical Vapor Deposition (CVD)CVD is a kind of chemical technology, which mainly uses one or several vapor compounds or elements to make chemically react on the surface of the substrate to form a thin film.
Thin FilmsThickness of HG nano dies are less than 0.3mm,which will give exact diameters to your wires and tubes.
Grain Size of The CoatingThere are micron coating and nano coating dies in market. Our coating is in nano grade. So your wires will have smooth surface.
Applications of Nano Dies
Nano dies can be mainly divided into following 3 kinds according to their applications.
Compacting Nano DiesCompacting nano dies have long service time to improve your production efficiency.
Nano Dies for WiresIn wire drawing, life time of nano dies is about 20 times as that of tungsten carbide dies.
Nano Dies for TubesSizes of HG nano dies for tubes are usually big.You will find their good cost performance.
High Quality Coating Film
Quality of coating film is very important to a nano die because its life time decides the nano die’s life time. HG nano coating is abrasive resistant and impact resistant to keep a long service time in wire drawing. At the same time, your wires’ surface and diameters are also controllable.
Even thickness of Coating Film
Coating film of nano dies are very thin but it must be coated on the inner surface of tungsten carbide dies evenly to ensure your drawing materials’ accurate diameters and smooth surface. In addition, the coating film will adhere the inner surface of tungsten carbide tightly to get a long life time.
Small Grain Size of Coating Film
Generally speaking, there are micron-grade coating films ( grain size from 0.1 to 100 microns) and nano-grade coating films (grain size from 1 to 100 nm) in the market. Compared with another coating film in microns, HG nano dies’ nano-grade film will give a very smooth surface to your wires and tubes.
Long Service Time and No Need of Recuting
Service time of nano dies are about 20 times as that of tungsten carbide dies in same diameters. Your production efficiency will be much improved because there is no need to change dies frequently.
Moreover, you do not need to recut nano dies.
There is a thin coating film on inner surface of nano dies and the coating is diamond. But the substrate is tungsten carbide. So nano dies combined the advantages of diamond dies and tungsten carbide dies.
They are made by a special chemical method, Chemical Vapor Deposition (CVD) to form the diamond film on inner holes of tungsten carbide dies.
Compared with PCD dies in same diameters, nano dies’ price will be much cheaper. And surface of wires drawn by nano dies will be smoother.
With the diamond coating, nano dies’ life time will be much longer than that of tungsten carbide dies.
Price differs from different diameters of nano dies. Generally speaking, the diameters is bigger, the price is higher.
For normal nano dies orders, the delivery time will be not more than 20 working days.
