2007 Acquisition of HENKEL’s wire-drawing activity

A wire-drawing section composed by a double-wire rod breakdown machine (15 steps), a single-wire rod breakdown machine (6 steps) and two multi-wire drawing machines (16 wires and 8 wires in parallel)

The wire-drawing speed is preferably 1,200 m/min or greater, even more preferably 1,500-2,300 m/min.

Wire-drawing operations are often designated as areas where eye protection must be used.

More recently, smaller autonomous factories have their own, smaller wire-drawing operation.

The final tandem drawing block (56) of the first wire drawing section is arranged on the second wire drawing section.

A first wire drawing section (12) includes two pairs of cone drawing blocks (20, 22, 36, 40) and two tandem drawing blocks (48, 56).

The dancer roller is linearly moved substantially in parallel to direction of wir drawing of the wire drawing die, whereby the wire drawing unit can be reduced in width.

wire rod intended for cold extrusion or fine wire drawing

This copper alloy wire rod can be obtained by carrying out the wire drawing step and processes after the wire drawing step at a temperature less than 500°C.

Single and multi-wire drawing apparatus and method are described.

A plurality of such wire drawing units can be placed between the wire supply unit and the wire winding unit in multiple rows so as to further reduce the width of the wire drawing machine.
