LD-630 high-speed double-twist wire binding machine

Production Range

· Copper wires and Unilay strands (19 or 37 wires), starting from 0.10 mm (0.0039 in).

· Cross-sectional area from 0.06 to 6 mm² (flexible bundles); for 7- and 19-wire constructions, standard bow configurations are available up to 4 mm.

· Minimum individual wire diameter for stranding: 0.1 mm (0.0039 in).

· Stranding of 7, 19, or 37-wire configurations using hard-drawn or annealed copper.

· Stranding of 2 to 8 insulated conductors (using an optional special bow); maximum diameter: 5 mm (0.19 in).

Production Capacity:

· Production speed: Up to 5,500 twists per minute (TPM) for copper, depending on the specific product being manufactured.

· Line speed: The maximum practical line speed for conductors is 200 m/min (656 ft/min) to 1,000 ft/min, depending on factors such as pay-off quality, wire quality, and internal friction within the machine. For insulated products, the maximum speed is 100 m/min (328 ft/min).

· Lay length range: 2 mm – 160 mm.

General Information
