Nano Diamond Coated Dies for Wire Tube Drawing and Stranding
Nano diamond coated die, which also called CVD diamond coated die. Through the coating method of CVD chemical deposition, the entire interior surface of the tungsten carbide drawing die is plated with the nano-diamond layer, which thickness is 30um. Thereby improving the surface finish, reducing the friction force, and prolonging the service life.
Nano dies is ideal for cable stranding, bunching & compacting, wire drawing, and tube drawing. Aluminum, copper and other non-ferrous cable, dry-drawing of steel and stainless steel, welding wire drawing and tube drawing.
Specification:
Diamond coating dies are available from 0.7mm to 80mm;
Coating thickness: 30um;
Application:
Nano Diamond Coated Stranded Wire Compacting Die is used for stranded cable used in electrical transmission, stranded copper and stranded aluminum, etc.
Nano Diamond Coated Wire Drawing Die is used for wire and tube drawing, which includes welding wire drawing (Low carbon steel wire, high carbon steel wire) stainless steel wire, aluminum wire and copper drawing, etc.
Advantages:
1. Diameter up to Ø80mm, wider diameter range than the PCD dies;
2. Improve the wire mould working life;
Drawing copper wire, aluminum wire, low carbon steel wire, medium carbon steel wire, the die life is more than 20 times that of tungsten carbide die.
3. Save raw materials
Due to the constant hole diameter, the drawn wires have good consistency, and the wire mold does not need to be repaired.
4. Improve the surface finish of the wire
Because the particle size on the surface reaches the nanometer level, the surface finish of the drawn wire is high.
5. Water lubrication instead of oil lubrication
Due to the nano-scale particles on the surface, it has good hydrophilicity and good self-lubrication, which greatly reduces the cost of drawing oil, saves metal materials, reduces environmental pollution, and improves the working environment.
6. 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.
