Tungsten Carbide Wire Drawing Dies and Nano Coated Wire Drawing Dies

Tungsten carbide , also called cemented carbide , is a composite of tungsten carbide particles and metal cobalt. Tungsten carbide is a non-oxidizing hard alloy that maintains a similar hardness to corundum or gemstones even at very high temperatures . Tungsten carbide has been used as a core for wire drawing dies for more than 100 years and is still widely used.
The nano coated drawing die is made of tungsten carbide die, which is modified and specially pretreated, and then coated with multi-layer micron-nanometer diamond film by ultra-vacuum equipment, which obviously improves the wear resistance of the die core and the service life of the die.

Tungsten Carbide Wire Drawing Dies Product Introduction
Tungsten Carbide Wire Drawing Dies Product Introduction​
In the dynamic realm of metal processing, Tungsten Carbide Wire Drawing Dies stand as indispensable tools, leveraging high-quality cemented carbide as the core mold core. These dies combine precision engineering with exceptional performance, making them the go-to choice for enterprises aiming to optimize production quality and efficiency.
I. Core Functions and Industry Applications

Tailored for diverse metal wire drawing operations, Tungsten Carbide Wire Drawing Dies excel in shaping galvanized steel wire, copper-plated steel wire, and more. In the wire and cable industry, they ensure consistent wire diameters and smooth surface finishes, vital for electrical conductivity. In wire mesh production, they enable the creation of meshes with precise dimensions, while in spring manufacturing and fastener processing, they guarantee wires meet strict mechanical property requirements.​
The dies' effectiveness stems from their precisely designed drawing plates and dies, which accurately reduce or modify metal wire cross-sections. This allows manufacturers to produce wires of various gauges and profiles, catering to both delicate microelectronics and heavy-duty industrial applications.The dies' effectiveness stems from their precisely designed drawing plates and dies, which accurately reduce or modify metal wire cross-sections.

II. Outstanding Product Performance
1. Versatile Diameter Range
With a diameter range of 0.05 - 35mm, these dies accommodate a wide spectrum of wire sizes. From ultra-fine wires for microelectronics and medical devices to thick wires for construction, they offer unmatched adaptability, meeting diverse industry needs.
2. Exceptional Physical Properties
High Hardness & Wear Resistance: The ultra-high hardness of cemented carbide provides superior wear resistance. This enables the dies to endure the intense pressure and friction of wire drawing, especially when working with hard materials like high-carbon steel, extending their lifespan and reducing replacement costs.
Good Thermal Conductivity: Efficient heat dissipation is ensured by the dies' excellent thermal conductivity. This prevents thermal expansion, maintaining dimensional accuracy during high-speed drawing operations and reducing the risk of die damage.
Low Friction Coefficient: A low friction coefficient minimizes resistance between the wire and die, facilitating smooth wire drawing. This reduces surface defects, improves wire quality, and decreases power consumption, enhancing both productivity and cost - effectiveness.
3. Cost - Effective Solution
Compared to similar products, Tungsten Carbide Wire Drawing Dies offer significant cost advantages. Their long service life, combined with reduced maintenance and replacement needs, makes them a cost - effective choice, especially for wire processing with high die wear or hard metals.
4. Stable and Durable Operation
Uniform wear during use ensures consistent performance over time. This stability guarantees that metal wires maintain precise dimensions and quality, while the dies' ability to withstand 2800°C temperatures expands their application to high - temperature wire drawing processes.

Repair & Maintenance

The die is an important part of the drawing process, but it is important to understand that it is part of a chain and that its performance is linked to other parts like the machine, the lubricant, the raw material, etc. So, it is important to make sure that all these elements work together in the best way possible. Nevertheless, even when all the drawing conditions are under control, the drawing process puts wear in the dies; the wire leaves marks on the diamond surface and die maintenance becomes necessary. Problems such as ring wear in the reduction zone, increase of the aperture in the bearing zone and decrease of the surface finish may eventually lead to blank ruptureanddie scrap.

We provides customers with die repair and maintenance service .In strict accordance with the standards of new dies, the used dies are modified in aperture and the inner surface of the blank is reshaped andre-polished , thus significantly prolonging the service life of the dies and reducing the production cost for customers.
