RLB metal wire and product production lines deliver efficient manufacturing of copper and aluminum wires and related products for the cable industry. Our systems ensure high productivity, excellent quality and full process control. Custom solutions available.

Aluminum Clad Steel Wire Production Line

In the demanding field of overhead power transmission and optical ground wire (OPGW) manufacturing, aluminum-clad steel (AS) wire and soft aluminum sheathing must deliver exceptional conductivity, mechanical strength, and long-term corrosion resistance.

The RLB Continuous Cladding Aluminum Clad Steel Wire Production Line (models RLB315/132, RLB350-2/200, and RLB400-2/250) provides a proven tangential continuous extrusion solution that produces uniform, high-integrity aluminum cladding in a single high-speed pass — ideal for AS wire and soft cladding applications in OPGW and fireproof cables.

Aluminum Material Continuous Extrusion Machine For Aluminum Busbar & Tube Wholesale Factory

The Aluminum Continuous Extrusion Machine delivers single-step, high-speed production of precision aluminum conductors, busbars, porous flat tubes and complex profiles directly from rod feedstock. Engineered for new energy, power transmission and electrical equipment manufacturers seeking superior surface quality, uniform microstructure, energy efficiency and minimal downstream processing.

Aluminum Sheath Argon Arc Welding Pipe Production Line

High-efficiency continuous production line for argon arc (TIG) longitudinal welding of aluminum (or copper/stainless steel) strips into precision metal sheath pipes, followed by sizing and optional corrugation. Designed for power cable metal sheathing, delivering superior radial water-blocking, short-circuit capacity, mechanical strength and lighter weight compared with traditional lead sheaths. Supports OD 8–200 mm, aluminum thickness 0.3–4.0 mm, speeds up to 20 m/min. Ideal for MV, HV, UHV, fire-resistant and railway cable manufacturers seeking reliable, customizable, long-term production solutions.

Continuous Extrusion Machine for Copper

Professional continuous rotary extrusion (Conform) machine for copper that transforms oxygen-free copper rod (typically Φ12.5–30 mm) into soft, high-conductivity busbars, rectangular flat wires, round conductors, and custom profiles in one continuous step. Achieves first-pass yields of 95%+, significantly lower energy consumption, refined grain structure, and unlimited product length. Designed for power cable, transformer, switchgear, railway, and new-energy applications. Custom configurations available with full turnkey support.

Technical guide to copper wire annealing and tinning machines: process, parameters, ASTM B33 compliance, selection criteria and failure prevention for cable manufacturers.

Copper Wire Enameling Machine

The Copper Wire Enameling Machine delivers high-speed, precision enameling for fine to thick magnet wire (Φ0.04–3.50 mm). Available in horizontal, vertical, and integrated drawing+enameling configurations with catalytic VOC control (≤20 mg/m³), multi-pass coating up to 13 passes, and thermal class up to 220°C. Ideal for motors, transformers, automotive, and high-efficiency windings.

Galvanized Steel Wire Production Line

High-performance multi-wire continuous hot-dip galvanizing production line for steel wire (typically 1.6–4.0 mm or custom ranges). Delivers uniform zinc coatings of 40–450 g/m² (or 145–255 g/m² standard heavy coat), processes up to 24–40 wires simultaneously, with DV values 120–180. Engineered for ACSR conductors, power cable armoring, fencing, gabion mesh, and structural wire. 24/7 continuous operation, low zinc consumption, superior adhesion and corrosion resistance.
