The core of the diamond wire-drawing tool is the core of wire drawing tools. It can be divided according to material into three types: single crystal, CVD and PCD core. For PCD drawing dies are the wire drawing tools that have PCD core.
What are the differences between wire drawing cores of different types?
PCD mold core – The PCD wire drafting dies industry has seen significant improvement since the successful creation of PCD. The whole process is more stable and efficient. PCD can now be achieved by sintering tiny diamond and binders at high temperatures and high pressures. It is very durable and hard. It has a long-lasting durability, uniform wear and is very durable. This mold is perfect for high speed drawing. It is macroscopically iotropic and won’t suffer from die hole wear or have out-of-round cavities like single-crystals. It is also significantly cheaper than single crystal diamonds so it has been extensively used in wire drawing. For wire drawing, the majority of diamond wire-drawing tools use PCD cores.

CVD core: A CVD (or chemical-vapor deposition) diamond is a natural diamond that has been formed on a substrate using carbon-containing gases. It can be deposited at high temperatures under low pressure and in high temperatures. A CVD diamond is hard, durable, and has a low friction and wear resistance. It can be used to create wire drawing tools with an aperture between 0.02-1.0mm. These tools are suitable for drawing stainless steel and tungsten as well copper and molybdenum. The CVD diamond wire drawings tools have a better wear resistance, corrosion resistance, thermal conductivity and heat resistance than the PCD. However, there are some limitations to this product. It is not as tough as PCD, it has lower impact resistance and cracking strength, and its wire drawing process is more rigorous than PCD.
One crystal diamond diamond core: A single crystal is a diamond that has the characteristics of high hardness, excellent wear resistance and exceptional durability. This mold can produce pcd high-finish dies. Due to its anisotropy, the wire’s hardness can be anisotropic. If the hole in the die is worn unevenly, it will result in a product that is not round. This die is very expensive and is best used for wire drawing. There are two types available single-crystal diamond wire drawing cores: natural or artificial single crystal cores. Imports are the most important source of manmade single-crystal, diamond wire drawing centers. Element Six and Sumitomo of Japan are just a few of the notable manufacturers. Langfang Sipor Company is another.
What are the differences between different types of cores for PCD?
Different bonding agents make it possible to distinguish between two types PCD cores: cobalt and silicon-based.
The core of the PCD, which is cobalt-based, has a metal connection and can be machined. It can also be processed using ultrasonic or laser. Because of the presence metal cobalt, diamond is not easy to graphitize at high temperature. This mold can only be used in temperatures below 650°C. Get more info, Visit here: www.szwiredie.com
The PCD core of silicon-based, PCD isn’t very usable but there is no metal link so it can still be stable at temperatures above 1000 degrees Celsius.
