Fine metal wire drawing

Cold rolling lines

Shanghai Lizhi Machinery Co Ltd is specialised in the research and development of micro-fine and fine metal wire drawing and annealing equipment for precious metal, non- ferrous metal, ferrous metal and stainless steel. The LZDM-80/21 wiredrawing 1. machine is suitable for drawing extremely thin, precious metal wire rod. The maximum inlet diameter is 0.12mm with a minimum finished wire diameter of 0.015mm. The machine speed is 600 metres per minute. The drawing process is completely automatic, with a PLC-programmed control system. Ten pre-programmed operations can be stored.

This is Teurema’s rolling line for the production of smooth and/or ribbed wires. The line is extremely compact and equipped with protections to safeguard the operator. In the basic version, the line is provided with vertical or horizontal spooler for the production of spools or coils. It can also be used for the in-line supply of the wire mesh lines.

Teurema’s LG cold rolling lines ❍ ❍

The wire rod, from the coil positioned on the tilting fingers, will run through the vertical static payoff, the mechanical descaler, the lubricant adding unit and the Eurolls rolling cassettes, until it reaches the capstan that guarantees the necessary pulling force for the cold rolling deformation. A spooler positioned after the bullblock will collect the wire.

The LZDM-80/21 precious metal thin ❍ ❍ wiredrawing machine

Inlet wire rod: from diameter 5.5 to diameter 16mm Outlet wire: from diameter 4mm to diameter 14mm Wire reducing by means of cassettes AC speed variable motors Cabinet

The LZDM-480/01 is suitable for 2. drawing extremely thin, precious metal wire rod bus bar. The maximum inlet wire diameter is 8mm with a minimum finished wire diameter of 1.5mm. The machine speed is 50-80 metres per minute. This single- drum wiredrawing machine grad- ually decreases the wire diameter by threading wires through one die until the target wire diameter is reached. Settings such as drawing speed and traverse pitch can be set up for every process via a touch panel on the 10.4" colour touch screen.
