Nano Diamond (CVD)
Nano Diamond (CVD) coating is a relatively new technology that we have been working with since 2010. The technology has developed a lot in recent years, and its main method is to coat a diamond film on a pre-profiled carbide core that is successfully used in wire drawing discs. The diamond film is pure diamond polycrystalline. It not only has the smoothness and temperature resistance of single crystal diamond, but also has the advantages of (PCD) polycrystalline diamond wear resistance and low price. It has achieved good results in replacing rare earth (ND) natural diamonds in the production of wire drawing dies. Its wide use will bring new vitality to the wire drawing industry. Process and technology: Targeted pretreatment process: to make the coating and the substrate closely combined Micro-diamond coating: excellent wear resistance Surface nano-diamond coating: excellent surface finish and low coefficient of friction Optimization of passport design through computer simulation
The advantages of NANO diamond coated tools are as follows: 1. Long service life: the service life of copper aluminum wire, low carbon steel wire, medium carbon steel wire, cable stranded wire, welding wire and matrix is 20-30 times more than that of hard metal mold, and that of cable stranded wire is more than 50 times that of hard metal. 2. The size control precision is high, the wire size is stable, and the size consistency can be maintained for a long time. 3. The inner hole of the mold is bright, the self-lubrication is good, the surface friction coefficient is small, the surface finish of the rolling wire is high, the material is not sticky, the quality of the finished wire is good, and the loss of equipment and equipment can be reduced at the same time. 4. The wire length is 1%-2% longer than that of traditional shape. 5. Repair-free mode, maintenance-free, reduce the number of outage detection, mold replacement, greatly improve production efficiency, unit time production greatly increased, saving a lot of labor costs. 6. It is suitable for drawing process without pickling, environmental protection and energy saving. Nano Diamond Compacting Dies are used to guide and/or organize the wire through the bundling machine and stranding machine, the winding drum of the double and single twist machine is inside the machine, and the pad is fixed at the entrance of the machine to collect the wire. In some cases, the die is attached to the front of the winding drum inside the machine to regulate the wire, and the wire die of the tube and basket strander is inside the machine to guide and concentrate the wire.
