In today’s high-demand electrical power transmission, new energy vehicle and industrial equipment sectors, manufacturers need fast, cost-effective and consistently high-quality copper conductor production. The Bakır Malzeme Sürekli Ekstrüzyon Makinesi (Conform continuous rotary extrusion line) provides a proven single-wheel lateral extrusion solution that converts oxygen-free copper (OF Cu) rods directly into soft, high-conductivity round wires, flat wires, busbars and complex profiles in one continuous, high-speed process.
With extended extrusion belts, specially heat-treated wheels and industry-leading low leakage rates (≤3–5 %), the RLB series achieves uniform microstructure through dynamic recrystallization, excellent surface finish and superior electrical performance while dramatically reducing material waste and energy consumption compared with traditional multi-step drawing or hydraulic extrusion methods.
The Conform Continuous Rotary Extrusion Process for Copper
The RLB Copper Continuous Extrusion Machine employs advanced continuous rotary extrusion (CRE / Conform) technology. Oxygen-free copper rod feedstock is fed into a precision-grooved rotating extrusion wheel. Intense friction and controlled pressure generate localized heat, bringing the material into a plastic state where dynamic recrystallization occurs. The material then flows into the die chamber and exits as finished high-conductivity product of unlimited length in a single, continuous operation — without the need for preheating or post-extrusion annealing in most applications.
Key advantages for copper processing:
- Preserves and enhances the inherent high conductivity of oxygen-free copper
- Produces soft temper material ideal for direct bobbin take-up or further forming
- Excellent bendability and formability for complex busbar shapes used in EV and switchgear
- Significantly higher material yield and lower energy use than traditional routes
Advanced Engineering Features & Process Benefits
Lengthened Extrusion Belt & Heat-Treated Wheel
Extended dwell time ensures complete compaction and dynamic recrystallization, delivering dense, homogeneous microstructure with exceptional electrical conductivity and long-term thermal stability. Special heat treatment extends wheel service life under demanding high-pressure and high-temperature conditions.
Single-Wheel Single-Groove Lateral Extrusion
Provides stable high-speed production with precise dimensional control (typical tolerance ±0.05 mm) and outstanding repeatability — critical for tight-tolerance copper busbars and flat wires used in high-current applications.
Soft Extruded Products – Annealing-Free
Copper exits in soft temper, ready for direct bobbin take-up. Optional integrated online cutting saw delivers precise length control for busbar and profile production, eliminating costly and energy-intensive annealing steps.
Compact Intelligent Full-Line Layout
Complete production line includes: horizontal pay-off system, wire straightener, continuous extrusion main machine, cooling & anti-oxidation system, length counter, caterpillar tractor, constant-tension take-up and receiving stands. All modules are linked by automated conveying for seamless 24/7 operation. Centralized PLC + HMI touchscreen with industrial cloud data traceability and remote diagnostics module enables real-time monitoring, parameter adjustment and predictive maintenance.
Energy-Efficient & Eco-Friendly Design
No preheating or annealing required. Integrated hydraulic system with zero oil leakage. Mechanical locking of extrusion tooling guarantees stable process conditions. One or two operators can efficiently manage multiple lines.
Premium Components & Continuous Improvement
Upgraded high-quality gearbox, Siemens/ABB electrical controls, aviation plugs for fast connection, constant-tension take-up and automatic short-rod feeding. Dedicated R&D team and independent laboratory support annual machine improvements and customer-specific material testing.
These features make the RLB Copper Continuous Extrusion Machine the preferred choice for producers seeking higher throughput, lower operating costs, reduced scrap and consistent premium quality in copper busbar, flat wire and profile manufacturing.
