Copper wire drawing: introducing PCD MANT® dies by Redies

Redies, an internationally recognized manufacturer of tools for metal wire processing, offers an advanced range of drawing dies for copper wire based on polycrystalline diamond (PCD) technology. By utilizing PCD MANT® dies, Redies ensures high performance, longer tool life, and excellent drawing results, even in the most demanding processes.

Comparing PCD and Natural Diamond (ND) Dies

Wire drawing dies can be manufactured using natural diamond (ND) or polycrystalline diamond (PCD), each with its unique characteristics. Let’s explore them:

Natural Diamond (ND):

- Provides the highest surface quality for the drawn wire.
- May exhibit higher ovality due to the material's directional hardness, resulting in uneven wear in certain areas.

Polycrystalline Diamond (PCD):

- Ensures isotropic hardness, reducing directional wear and preserving the cylindrical shape of the wire.
- Produces a slightly less refined wire surface compared to ND, but offers significantly superior overall tool life.
- Wear is evenly distributed thanks to its lattice structure, achieved through a high-pressure and high-temperature sintering process.

PCD MANT® dies: durability and enhanced product quality

PCD MANT® dies represent a technological breakthrough for the wire drawing sector. Using sintered diamond powders, these dies combine superior mechanical properties with exceptional wear resistance. The mechanical polishing process ensures perfectly smooth surfaces, enhancing the quality of the drawn wire.

PCD inserts with a grain size of 1 μm achieve a balance between precision and longevity. These dies typically last 2-4 times longer than ND dies, even when used for fine wire diameters (as small as 0.15 mm). They are well-suited for multi-wire machines, making them an effective alternative to ND dies for high-precision tasks.

A notable feature of the polished surfaces of PCD dies is the presence of microscopic "lubricant pockets," a result of their polycrystalline structure. These pockets enhance lubrication during the drawing process, reducing friction and extending the tool's lifespan.

For copper wire drawing, PCD MANT® dies provide a practical solution that balances product quality and tool durability. They are a reliable option for manufacturers seeking efficient and high-quality wire drawing tools.
