In today’s high-volume fine wire manufacturing environment, cable plants face constant pressure to increase output, maintain strict diameter and surface quality consistency, reduce labor and energy costs, and minimize workshop footprint. The Multi Wire Drawing Continuous Annealing Machine (RDB series) is engineered precisely for these demands.
This advanced multi-head production line simultaneously draws 8 to 24 copper wires from a maximum inlet diameter of Ø1.8 mm (RDB80/RDB100) or Ø2.6 mm (RDB120) down to ultra-fine finished sizes between Ø0.14 mm and Ø0.50 mm, while performing fully synchronized online continuous annealing in a single continuous pass. The result is bright, soft, uniformly annealed fine copper wire ready for subsequent bunching, stranding, or enameling processes — delivered at mechanical speeds up to 1800 m/min.
Designed for electronic wires, magnet (enameled) wire precursors, automotive harness conductors, communication cables, medical and aerospace specialty wires, and multi-strand flexible conductors, the RDB series solves the classic productivity bottlenecks of single-wire lines: excessive floor space, high labor intensity, elevated energy and lubricant consumption, and inconsistent annealing quality.
Brief Technological Process
Incoming copper rods/wires (Ø1.8–2.6 mm max) → Multi-head drawing section (8/16/20/24 wires) equipped with ceramic (zirconia or single/double-layer ceramic) drawing wheels → Precision tension control system → Integrated continuous annealing unit (digital voltage control, typically 3–4 stage, steam-protected) → Multi-stage cooling & drying → Automatic take-up on shared large bobbins (Φ600–800 mm) or individual spools with pneumatic clamping, lifting and anti-reverse safety functions.
The entire line is governed by an advanced PLC + MMI (touch-screen) system that ensures full mechanical and electrical synchronization, real-time process monitoring, automatic annealing voltage adjustment proportional to drawing speed, parameter storage/recall, and user-friendly operation.
Core Technical Advantages & Performance Excellence
Engineered specifically for high-volume fine wire production in Saudi Arabia and GCC cable plants, the RDB Series delivers measurable, quantifiable benefits:
- Multi-Head Simultaneous Processing 8–24 wires drawn and annealed at the same time. Compared with equivalent single-wire lines, this configuration typically reduces electricity consumption by 30–50 %, lubricant usage, labor intensity, and required workshop space while significantly increasing overall throughput.
- Integrated Continuous Annealing Fully digital voltage control automatically tracks drawing speed. Combined with insulated guide wheels and multi-stage annealing, it produces soft, bright wires with excellent and consistent elongation (typically 25–33 %), uniform mechanical properties, and superior surface finish — eliminating the need for separate offline annealing and reducing work-in-process inventory.
- Premium Ceramic Drawing Wheels Single or double-layer ceramic (or zirconia) cones offer exceptional wear resistance, long service life, and rapid, easy replacement. This minimizes downtime and maintains precise diameter control over extended production runs.
- High-Speed Operation with Minimal Downtime Maximum mechanical speed of 1800 m/min, supported by a fast die-change system and pneumatic bobbin handling. Larger shared bobbins further reduce changeover frequency and joint points, improving continuity and downstream processing efficiency.
- Intelligent MMI + PLC Control Touch-screen interface enables real-time synchronization, online monitoring of all critical parameters, recipe storage, and simple operator intervention. Micro-slip control and automatic tension adjustment ensure stable running even at top speeds.
- Complete Turnkey Integration Capability Optional auxiliary equipment includes automatic threading machines, heat exchangers, steam generators, and advanced filtration systems for lubricant and cooling circuits — allowing seamless integration into existing or new cable plants.
These design features translate directly into higher net output, lower total cost of ownership, reduced scrap rates, and consistent high-quality fine copper wire that meets the stringent requirements of modern electronic, automotive, and specialty cable applications.
