In fine copper wire manufacturing, achieving ultra-fine diameters with consistent softness and high surface quality is essential for electronic cables, magnet wires, automotive harnesses, and specialty conductors. The Double Wire Intermediate Wire Drawing Machine with Continuous Annealing (RZL280 series) is a high-efficiency solution that draws incoming copper wire from Ø2.6–3.5mm down to a minimum of Ø0.4mm while performing online annealing in a single continuous pass.
Available in single-head and double-head configurations, this intermediate drawing line maximizes output, reduces floor space requirements, and delivers bright, uniformly annealed fine wire ready for further processing or bunching.
Brief Technological Process
Incoming Wire → Double-Head Drawing → Online Continuous Annealing → Final Take-Up Copper rod (Ø2.6–3.5 mm) → Tungsten carbide treated extension wheels & drawing cones → Straightening & tension control → Medium-frequency or DC continuous annealing (3000 A / max 50 V) → Cooling & drying → Automatic dual spooler or vertical coiler → Finished soft fine copper wire (Ø0.4–2.76 mm).
The entire line operates under full PLC + HMI synchronization, with real-time monitoring of speed, tension, annealing current/voltage, and emulsion flow.
Core Technical Advantages & Performance Data
Engineered for high-volume fine wire production in Saudi Arabia and GCC cable plants, the RZL280 series offers measurable advantages:
- Double-Head Capability (RZL280-17/2): Processes two wires simultaneously, doubling output without extra operators — ideal for mass production of identical-specification wires.
- Tungsten Carbide Treated Drawing Wheels: Four groups of multi-layer cones with tungsten carbide surface treatment provide exceptional wear resistance (service life 2–3× longer than standard), low maintenance, and consistent diameter control.
- Integrated Continuous Annealing: DC annealing system (3000 A / max 50 V, 195 kVA) produces soft wire with 25–33% elongation directly from the drawing process, eliminating separate annealing steps and reducing handling damage.
- High Drawing Speeds: Up to 25 m/s (1500 m/min mechanical speed) with frequency-controlled AC motors (75–280 kW main power).
- Intelligent MMI + PLC Control: Full-line synchronization, recipe storage for different diameters/annealing parameters, and touch-screen operation — reduces operator intervention and ensures stable 24/7 production.
- Flexible Configurations: Compatible with single spooler, automatic dual spooler, or vertical coiler; optional threading machine, heat exchanger, steam generator (9 kW, 12 kg/h steam), and filtration systems for turnkey operation.
Production Speed Data (Double Wire, Soft Annealed):
- 2 × Ø0.8 mm → 1200 m/min
- 2 × Ø1.0 mm → 1000 m/min
- 2 × Ø1.2 mm → 700 m/min
- 2 × Ø1.6 mm → 700 m/min (25–33% elongation)
These features deliver 30–50% higher productivity, lower energy consumption per ton, and superior wire quality compared with conventional single-head systems.

Detailed FAQs – Answering Real Customer Questions
Q1: What is the advantage of double-head configuration?
A: The RZL280-17/2 model draws two wires simultaneously, doubling productivity while using the same floor space and operator — ideal for high-volume identical-specification fine wire production.
Q2: How does online continuous annealing improve wire quality?
A: Integrated DC annealing (3000 A / max 50 V) produces soft wire with 25–33% elongation directly after drawing, eliminating separate annealing, reducing oxidation, and ensuring uniform softness and bright surface.
Q3: What is the typical service life of the tungsten carbide wheels?
A: 2–3× longer than standard wheels due to tungsten carbide surface treatment; easy maintenance with quick-change design.
Q4: What power and utilities are required?
A: Main motor 75–290 kW (frequency conversion), compressed air 0.6–0.7 MPa (50 L/min, dew point -25°C), steam generator 9 kW. All systems are energy-efficient with frequency inverters.
Q5: Can the machine integrate with my existing bunching or extrusion line?
A: Yes. Compatible with WS series single/dual spoolers and WF series coilers; we provide full synchronization and turnkey integration.
Q6: What is the expected payback period?
A: 12–18 months through doubled output (double-head), reduced scrap, lower energy use, and elimination of separate annealing steps.
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.
