The nano diamond coating dies are made from tungsten carbide, (WC — Co), as the substrate. Chemical vapor deposition is used in the dies of inner hole surface to form a layer of diamond growth. After precision grinding and polishing the diamond coating, the product has the cemented carbide dies toughness and wear resistance, high friction coefficient and long life.
Yihua diamond-coated dies allow for ultra-smooth wires and excellent conductivity. This allows you to lower costs. A diamond coated die is the perfect combination of large-sized tungsten carbide and synthetic diamond’s superior surface properties. You can save material and use less power, which will result in more profit when you strand.
Technology and Process:
-Targeted Pretreatment Process: To make the substrate and coating close together
-Excellent wear resistance
-Surface Nano-Coating: Excellent surface finish and low friction coefficient
-Computer simulation optimization por design: To make the wire uniform force
The advantages of nano diamond coating
1. Long service life: The service life of copper, aluminum, low-carbon steel wire, medium steel wire, wire capstan wire, wire and mold is 20–30% longer than that of hard alloy mould. Cable capstan wire is 50 times more durable than hard alloy.
2, Precision in size control, stable dimension, and constant dimension for a long period.
3. The mould’s inner hole is well-lit, self-lubricating properties are good, surface friction coefficient is low, wire material is nonsticky and smooth. Equipment and equipment loss can also be reduced.
4. Save raw materials and wire is 1–2% longer than traditional moulds.
5. No-repair mode and no maintenance reduce downtime detection and mold changes, greatly increase production efficiency, dramatically increase output per unit of time and save labor costs.
6. Suitable for pickingling and drawing without acid, environment protection and energy savings.
Cable makers can cut costs by using Nano Diamond Coated Dies that have excellent conductivity.
Multi-wire electric cables can be made by using a variety of methods, including stranding, compacting and bunching. A bunching or Stranding die groups single and multi-wire wires together. A compacting die compresses the multiwire strand to the desired form factor.
Yihua’s state-of-the art diamond coating technology gives the cable company the ability save material and manufacturing costs. This allows them to increase cable quality, reduce overall cost, and extend the life of their dies.
A tungsten carbide-die with a diamond coating provides the best wire and cable surfaces today. The DC (diamond coated) die is a combination of large-sized tungsten carbide and the superior surface properties that randomly oriented synthetic diamond offers.
Conductivity is the ability to conduct electricity through the wire’s surface. This is possible because of the smoother surface. The cable manufacturer can save material by using a smaller cable. By minimizing friction, diamond coated dies decrease the amount of power needed to bunch, strand or compact conductors.
