CVD Nano Diamond-Coated Wire Drawing Dies

CVD nano diamond-coated dies are manufactured using advanced Chemical Vapor Deposition (CVD) technology, forming a dense, ultra-hard nano-scale diamond film on the surface of tungsten carbide die blanks. This dramatically enhances the die’s wear resistance, thermal stability, and overall lifespan, making it ideal for demanding wire drawing operations involving hard or high-speed materials.

◆ Key Benefits:

• Ultra-Long Lifespan: Up to 30 times longer drawing capacity compared to conventional carbide dies under standard working conditions.

• Exceptional Surface Finish: Nano-polished mirror surfaces ensure smooth, scratch-free wire output.

• Superior Coating Adhesion: Advanced pretreatment enables strong bonding between coating and substrate, preventing delamination.

• High Thermal & Chemical Stability: Perfect for high-speed drawing and harsh environments.

• Broad Material Compatibility: Suitable for stainless steel, high-carbon steel, copper, aluminum, and special alloys.

• Reduced Maintenance: Fewer die replacements and lower overall tooling costs.

◆ Application Industries:

Welding wire production, electrical cables, precision medical wire, automotive wire components, high-end electronic conductors, and more.
