In high-volume copper wire production, the rod breakdown stage determines overall line efficiency, wire quality, and production costs. The RLB Copper Rod Breakdown Machine with Individual Motors is a premium rod breakdown line engineered to draw single or double Φ8mm copper rods into finished wires ranging from Φ1.2mm to Φ4.5mm in a single continuous pass. Available in both shunt-drive (LWHD series) and linear single-motor drive (LHD series) configurations, this machine delivers precise tension control, exceptional speed, and maximum uptime for modern cable manufacturing.
Brief Technological Process
Φ8 mm Copper Rod → High-Speed Multi-Pass Drawing → Optional Online Annealing → Take-Up Low-oxygen or oxygen-free copper rod (Φ8 mm) → Straight-line capstan arrangement with individual servo motors per capstan → Tungsten carbide drawing cones → Precision tension control → Optional integrated continuous annealing unit → Automatic single/dual bobbin or vertical pay-off → Finished high-conductivity copper wire (Φ1.2–4.5 mm).
The mechanical speed is fully synchronized with motor speed, and dies can be replaced quickly while bobbins are unloaded automatically without stopping the machine.
Core Technical Advantages & Performance Excellence
Engineered for high-volume copper wire processing in Saudi Arabia and GCC cable plants, the LWHD-450 / LHD-450 series offers measurable advantages:
- Individual Motor Drive per Capstan: Each drawing rim is independently powered by a servo motor, enabling precise compression ratio settings, easy die matching, and adaptability to different copper grades — resulting in superior wire surface finish and dimensional accuracy.
- High-Speed & High-Efficiency Operation: Up to 30 m/s mechanical speed with 9, 11, or 13 drawing passes on Φ450 mm capstans. Frequency-controlled AC motors deliver low energy consumption per ton and stable product quality with low operational noise.
- Single or Double Rod Capability: Dedicated dual-rod models (e.g., LWHD-450/9(2), LHD-450/9(2)) support simultaneous drawing of two rods, effectively doubling output without extra floor space — perfect for mass production of identical-specification wires.
- Rapid Die Change & Automatic Bobbin Handling: Dies can be replaced quickly; bobbins are unloaded automatically without stopping the machine, minimizing downtime and labor.
- Flexible Take-Up Configurations: Single bobbin, dual bobbin, vertical pay-off, or custom combinations to match any downstream process.
- Optional Online Annealing: Full integration with continuous annealing for soft, bright, high-ductility copper wire ready for further processing or bunching.
These features make the RLB copper rod breakdown machine the preferred choice for manufacturers seeking higher productivity, lower energy consumption, reduced scrap rates, and consistent high-quality copper wire.

Detailed FAQs – Answering Your Customers’ Real Questions
Q1: What is the main advantage of individual motor drive in a copper rod breakdown machine?
A: Each capstan is independently powered by a servo motor, allowing precise compression ratio settings, easy die matching, and adaptability to different copper grades — resulting in superior wire surface finish, dimensional accuracy, and lower noise compared to single-motor systems.
Q2: Does this machine support online annealing?
A: Yes. Full integration with continuous annealing produces soft, bright, high-ductility copper wire in one pass, eliminating separate annealing steps and improving overall copper wire processing efficiency.
Q3: What is the maximum drawing speed and output?
A: Up to 30 m/s mechanical speed. Double-rod models effectively double productivity while maintaining the same compact footprint.
Q4: What take-up options are available?
A: Single bobbin, dual bobbin, vertical pay-off, or custom combinations to match any downstream process.
Q5: What is the typical energy consumption and payback period?
A: Frequency-controlled motors deliver low energy use per ton. Most GCC clients achieve full ROI within 12–18 months through higher output, reduced scrap, and lower labor costs.
Q6: Can the machine integrate with my existing bunching or extrusion line?
A: Yes. We provide full synchronization and turnkey integration with multi-wire drawing, bunching machines, or extrusion lines.
Q7: Do you provide installation, training, and after-sales support in Saudi Arabia?
A: Yes. Full turnkey installation, commissioning, operator training (English), 24/7 remote diagnostics, and local spare parts stock in the Eastern Province.
