UNAVOIDABLE fines (abrasive particles) generation, the most destructive lubricant contaminants in wire drawing, is no longer an alarming phenomenon since the introduction of the Decalub green and dry rod preparation and wire lubrication by PDH coating system.

In demanding wire applications, the PDH die wear is reduced to about 0.2 microns per tonne, meaning the three-body abrasive wear is virtually eliminated. Generation of abrasive particles (fines), continuously liberated from the wire surface during drawing, are PDH captured, encapsulated and transported with drawn wire out of the machine.

The lubricant film created is of such a configuration as to induce a hydrodynamic lubricant activity causing migration of all lubricant contaminants without interference with the drawing die, meaning the removal of abrasive particles prevents die wear, enabling frictionless wire drawing at high speeds, and low temperatures.

The PDH high-performance specific coat is hard, having high density, adjustable in thickness, and is largely sufficient to retain all liberated abrasive particles from wire surface.

Applications include all plain carbon wires up to 0.98% carbon, coated or uncoated, and stainless steel alloy wires up to 26% chromium.
