wire drawing machines in metal stretching processing:

Wire drawing reduces the cross-section of a metal wire by pulling it through a die, which stretches the wire to reduce its diameter while increasing its length.

The stretching and work hardening of the metal during wire drawing enhances its tensile strength and resistance to deformation.

Wire drawing allows production of wires with precise diameters, from coarse wires to ultra-fine wires down to 5 microns.

Key parameters controlled in wire drawing include die geometry, draft angle, drawing speed, lubrication, and annealing between successive draws.

Wire drawing imparts excellent surface finish and dimensional precision if done under controlled conditions.

Common metals drawn into wires include copper, aluminum, gold, silver, nickel, steel, titanium, tungsten etc. Each material requires optimized process parameters.

In addition to circular cross-section, wires can be drawn into square, rectangular and hexagonal cross-sections for specialized applications.

Wire drawing is often combined with other metal forming processes like rolling, extrusion and bar drawing for best results.

Economics, speed and reliability makes wire drawing suitable for high volume production of metal wires.

Wire drawing machines range from compact bench-top units to large multi-wire drawing lines with automated control.
