ND drawing die stands for "natural diamond drawing die." It is a type of wire drawing die that is made from natural diamonds. These drawing dies are known for their exceptional hardness and wear resistance, making them suitable for use in high-volume wire drawing operations.
ND drawing dies are capable of producing wire with very high surface finish and consistency in diameter. They are commonly used in the production of wire for electrical conductors and cables, as well as in the manufacturing of mechanical components.
In addition to their durability and precision, ND drawing dies are also resistant to heat and chemical attack, making them suitable for use in a wide range of manufacturing environments.
What is ND Drawing Die?
A natural diamond drawing die is a precision tool used in the manufacturing process of wires, rods, and tubes made of a variety of materials. It is made from a single piece of natural diamond or synthetic diamond material, which is carefully shaped and polished to form a channel that serves as a guide for the wire or rod being drawn. ND dies are frequently used for drawing, tungsten filament wire, bonding wire (gold, copper, aluminum) Medical wire.
Features of ND Drawing Die
Durable
The natural diamond wire drawing die has high hardness and wear resistance and does not require a lot of maintenance during use to ensure uniform diameter of the processed metal wire.
Smooth Running
The life of the diamond wire drawing die is about 30-50 times that of the carbide die, so there is no need to stop frequently to replace the die during the wire drawing process, and the size of the wire drawn by it changes little.
High Efficiency
The surface of these dies has a metal coating, and when the wire is pulled through the diamond drawing die, the surface of the die can quickly interact with the surface of the wire while improving wire surface finish.
Wide Used
They have a wide range of applications, including electronic devices, radar, aerospace, etc., and are compatible with a variety of metal materials, including aluminum, tin, silver, etc.
Applications of ND Drawing Die
Cable Drawing
ND drawing dies are widely used in the wire drawing industry to produce wires of different sizes, for the drawing of ferrous flat bars such as steels or stainless steels and the drawing of non-ferrous materials such as copper, aluminum and their alloys.
Jewelry Making
ND drawing dies are used to produce wire, sheet, and other components that are required in the production of jewelry, of precious metals such as gold, silver, platinum and palladium.
Medical Industry
The dies are used in the medical industry to produce components that are required in the production of medical devices, such as wires, strings, and other parts.
Types of ND Drawing Die
Single Crystal Diamond Wire Drawing Dies
Single crystal diamond wire drawing dies are diamond tooling used in wire drawing processes to produce high quality and precise wires. These are made of a single crystal diamond and are the most common types used in wire drawing applications. They offer excellent wear resistance and surface finish.
Poly-Crystalline Diamond (PCD) Wire Drawing Dies
PCD Wire Drawing Dies (polycrystalline wire drawing dies) is composed of diamond powder under the action of Metal Catalyst (silicon), which is sintered by high pressure and high-temperature process. They are made of multiple small diamond grains fused together and are ideal for drawing fine wires. They provide good wear resistance and lower cost than single crystal diamond dies.
Multi-Wire Drawing Dies
Multi-wire drawing dies refer to dies used in wire drawing machines to pull multiple wires simultaneously through a die opening to produce a single multistrand cable or wire. These dies typically have several holes through which the wires pass, all contained within a single die block. These are designed to draw multiple wires simultaneously and are used in high volume production settings. They may be made of single crystal or PCD diamond.
Shaped Profile Dies
They are used in wire drawing and extrusion machines where material is drawn through or forced under pressure through the die. These are used to draw wires with specific cross-sectional shapes and may be made of either single crystal or PCD diamond.
Differences Between Diamond Wire Drawing Cores
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 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.
What You Should Know When Use ND Drawing Die?
If you wish to process with a wire drawing device, you must first understand the drawing process and relevant technical information. This will help you avoid unnecessary scrap or waste.
The direction of the diamond wire drawing die and the abrasive belt used to draw it must be accurately determined. If any errors are made, the die will not work.
It is recommended to wear gloves while working and hand protection should be provided to the work piece.
There is a strict prohibition against drawing wire on materials that don’t appear clear.
After drawing, the final product needs to be handled carefully and kept safe.
The wire drawing die is a consumable element used in the wiring machine. So make sure you take good care of the wire drawing machine die.
If the groove in the drawing die ring is visible to be widened, this will result in an increase in wear. If it is not repaired in a timely manner, wear will continue to increase, and repairs will be more challenging. If the damage is significant, cracks may be visible in the deep portion of the groove, which can cause the mold to completely break.
