In today’s high-volume fine wire production, manufacturers demand maximum output, consistent quality, and minimal floor space. The RLB Multi Wire Drawing Continuous Annealing Machine (RDB series) is a state-of-the-art multi-head production line that simultaneously draws 8–24 copper wires from Ø1.8 mm (or Ø2.6 mm on RDB120) down to ultra-fine sizes between Ø0.14 mm and Ø0.50 mm while performing online annealing in a single, continuous pass.
Designed for high-speed, high-efficiency operation, this multi-head wire drawing line solves critical challenges of space, labor, and productivity, making it the ideal solution for manufacturers of electronic wires, magnet wires, automotive harnesses, and specialty fine conductors.
Brief Technological Process
Multi-Wire Simultaneous Drawing + Online Annealing Incoming copper wires (Ø1.8 mm max) → Multi-head drawing section (8/16/24 wires) with ceramic drawing wheels → Precision tension control → Integrated continuous annealing unit (digital voltage control, 3–4 stage) → Cooling & drying → Automatic take-up on shared bobbins or individual spools.
The advanced PLC + MMI system ensures full synchronization, real-time monitoring, and automatic adjustment of annealing voltage according to drawing speed.
Core Technical Advantages & Performance Excellence
Engineered for high-volume fine wire production in Saudi Arabia and GCC cable plants, the RDB Series offers measurable advantages:
- Multi-Head Simultaneous Processing: 8–24 wires drawn and annealed at the same time, significantly boosting productivity while saving electricity, lubricant, labor, and workshop space compared to single-wire lines.
- Integrated Continuous Annealing: Digital-controlled annealing (full automatic tracking of drawing speed) produces soft, bright wires with excellent elongation (25–33%) and uniform properties — no separate annealing required.
- Premium Ceramic Drawing Wheels: Single or double-layer ceramic cones provide exceptional wear resistance, long service life, and easy replacement.
- High-Speed Operation: Maximum mechanical speed up to 1800 m/min with fast die change system and pneumatic bobbin handling.
- Intelligent MMI + PLC Control: Touch-screen interface for real-time synchronization, parameter modification/storage, and online monitoring — simple and user-friendly operation.
- Complete Turnkey Solution: Optional threading machine, heat exchanger, steam generator, and filtration systems for seamless integration.
These features result in higher output, lower energy and labor costs, reduced scrap, and consistent high-quality fine copper wire.
The result is bright, uniformly annealed fine wires with excellent surface finish and mechanical properties at line speeds up to 1800 m/min.
