Wire drawing is a metalworking process used to reduce the diameter of a wire by pulling the wire through a single, or series of, drawing die(s). There are many applications for wire drawing, including electrical wiring, cables, tension-loaded structural components, springs, paper clips, spokes for wheels, and stringed musical instruments
In drawing wire, the required deformation is accomplished by drawing the wire through the conical bore section of the die, hereby reducing the diameter through plastic deformation. During deformation, a thin film of lubricant between wire surface and die surface is essential to minimise friction, to reduce die wear, and to keep the die cool.
Natural diamond die
Natural diamond die produce the finest quality wire and are the most expensive. The core of a natural diamond die is made using industrial grade diamond stones that are mined from the earth. Each stone is selected, cut and sorted into a workable size.
