High quality surface finish at large sizes

Ultra-smooth wire and cable surfaces with excellent conductivity are achieved through the use of Esteves Group diamond coated dies, enabling you to reduce costs. A diamond coated die is the ideal combination of a large-size tungsten carbide die and the superior surface properties of synthetic diamond. Potential material savings and lower power usage add up to more profit for your stranding process.

Excellent conductivity through the use of diamond coated dies enable cable makers to cut costs.

Bunching, stranding, and compacting dies are often used to form multi-wire electrical cables. A bunching or stranding die groups single and multiple wires together, whereas a compacting die compacts the multi-wire strand to the required form factor.

State-of-the-art diamond coating technology of Esteves Group diamond coated dies give the cable company the ability to save material and manufacturing costs by increasing the cable quality, increase the life of the die while reducing overall cost.

The ultra-smooth layer of diamond on a tungsten carbide die ensures the smoothest wire and cable surface that is possible today. The DC die (diamond coated die) is an ideal combination of a large-size tungsten carbide die and the superior surface properties of randomly oriented synthetic diamond.

As electrical current flows through the surface of the wire, a smooth surface leads to higher conductivity than was previously obtainable by using tungsten carbide dies. This can enable the cable manufacturer to save raw material as the same conductivity is obtained with a smaller diameter cable. Diamond coated dies reduce the power required to bunch, strand, or compact the conductor by minimizing friction.

Possible material savings and lower power usage all add up to more profit for the wire and cable manufacturer.
