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.

State-of-the-art diamond coating technology and tight diameter tolerances of Esteves Group diamond coated dies give the cable company the ability to save material and manufacturing costs.

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

A smoother conductor surface leads to higher conductivity than was previously obtainable by using tungsten carbide or PCD dies. This enables a cable manufacturer to save conductor material as the same conductivity is obtained with a lighter cable. Diamond coated dies reduce the power required to bunch, strand, or compact the conductor by minimizing friction.

Material savings and lower power usage add up to more profit.
