Types of Diamond Drawing Dies
Single Crystal Diamond Dies
Single crystal diamond dies (SSCD) are renowned for their ability to produce ultra-fine wires with exceptional surface finishes. These dies are crafted from either natural or synthetic diamonds, providing remarkable durability and precision. Manufacturers like DS Hai focus on utilizing 100% pure diamond to ensure optimal quality.
Polycrystalline Diamond Dies
Polycrystalline diamond (PCD) dies are designed for higher production speeds and longer die life. They are versatile, suitable for a range of applications including automotive and medical wire production. Companies such as Esteves Group emphasize the performance of PCD dies in maintaining wire roundness while minimizing material usage.
Natural Diamond Dies
Natural diamond dies are preferred for high-performance applications where surface quality is paramount. Esteves Group’s natural diamond drawing dies (ND dies) are particularly noted for their ability to meet stringent wire diameter tolerances. Their mirror polish and smooth wire entry enhance die life and performance.
Tungsten Carbide Dies
For drawing steel and other hard materials, tungsten carbide dies provide a cost-effective alternative. They offer decent wear resistance and are suitable for various applications in the wire drawing process. Balloffet emphasizes the importance of choosing the right die according to the drawing conditions to enhance yield.
Multi-wire Die Sets
Multi-wire die sets are essential for manufacturers looking to increase throughput when stranding and compacting conductor wires. By matching the mechanical draft of the machine, these die sets ensure optimal performance and longevity. Companies like Sancliff specialize in this area, offering tailored solutions for diverse manufacturing needs.
