The core of a diamond wire drawing tool's wire drawing dies core is its core. You can classify it according to the material into one of three types: single-crystal CVD or PCD core. The PCD core-containing wire drawing tools are known as For PCD drawing dens.

PCD mold core: The PCD wire-drawing dies industry has seen major improvements since the successful development PCD. This makes the entire process more efficient and more stable. PCD is possible by sintering small-sized diamond particles and binders under high-temperature or high-pressure conditions. It is extremely hard and resists wear. It is durable and can withstand uniform wear. This mold is great for high-speed drawing. This mold is macroscopically inotropic, so it doesn't show die hole wear like single-crystal-diamonds. It's also cheaper than single-crystal, which makes it a popular choice for wire drawing. Most diamond wire drawing tools utilize PCD cores to draw wire.

CVD diamond core: Also known as chemical-vapor-deposition diamond, a CVD diamond is a pure diamond that was deposited on a substrate with carbon containing gases at high temperatures and low pressure. The CVD diamond is durable and hard with a low friction coefficient. It also has good wear resistance. It can be used for making wire drawing tools that have an aperture of 0.02-1.0mm. This is useful for drawing stainless, tungsten and molybdenum wires, as well as copper, molybdenum and copper wires. The CVD diamond wire drawing dies are more resistant to wear, corrosion resistance, and thermal conductivity that PCD. There are some drawbacks to this product. It is less durable than PCD, has a lower impact resistance and cracking capability, and wire drawing die preparation is more precise than PCD.

One crystal diamond core: A one crystal diamond is characterized by its high hardness and wear resistance. This mold produces high-quality dies that yield pcd. The wire's anisotropy structure makes it hard. The product won't be round if the die hole is not worn evenly. It is expensive so it is used for wire drawing and wire drawing dies that have very high quality surface requirements. There are two types of single-crystal single crystal diamond wire draw cores: natural and artificial. Imports are the primary source of man-made single crystal diamond wire drawing cores. Element Six, Sumitomo of Japan, and Langfang Sipor Company all make prominent products.
