Diamond coated dies

In modern wire drawing operations, the demand for higher productivity, consistent wire quality, and longer tool life has led to the development of advanced die technologies. Among these, Diamond coated dies have emerged as a reliable solution for manufacturers working with ferrous and non-ferrous wires.

Diamond coated dies are produced by coating a thin layer of nano Polycrystalline diamond over a precision-finished tungsten carbide. This coating provides extremely high hardness, superior wear resistance, and low friction characteristics, making the dies suitable for high-speed and continuous wire drawing applications.

One of the major advantages of diamond coated dies is their significantly longer life compared to conventional tungsten carbide and PCD dies. Under normal operating conditions, these dies can provide 20 to 30 times longer life than that of TC Dies for Copper, Aluminium cable stranding and low carbon steel drawing, and around 20 times for high and medium carbon steel subject to standard drawing conditions. The advantages are reduction in downtime, die replacement frequency, higher surface quality, higher productivity and decreasing overall production cost. The nano diamond layer also improves surface finish of the drawn wire, ensuring better dimensional accuracy and consistent quality.

Diamond coated dies are available in a wide size range, typically from 0.500mm up to 150mm. These dies are suitable for drawing steel wire, stainless steel wire, welding wire, and cable armouring wire. Also widely used in bunching, stranding and compacting in cable manufacturing. Due to their high wear resistance, they are especially recommended for applications involving high tension, high speed, or abrasive materials.

Another important benefit of diamond coated dies is the reduction of friction during the drawing process. Lower friction helps in reducing heat generation, improving lubrication performance, and minimizing wire breakage. This results in smoother operation and improved efficiency.
