In the production of high-performance fine copper wires for electronics, automotive harnesses, and specialty cables, precise annealing followed by uniform hot-dip tinning is essential for achieving excellent solderability, corrosion resistance, and long-term conductivity. The RLB Copper Wire Annealing and Tinning Machine (Model RLE-40H) is a compact, high-efficiency multi-wire line specifically engineered for softening and tin-coating ultra-fine copper wires ranging from 0.1 mm to 0.4 mm in a single continuous process.
With the capacity to process up to 40 wires simultaneously at speeds reaching 5 m/s, this machine delivers consistent, bright tin coatings while significantly reducing labor and energy costs compared to traditional batch annealing and tinning methods.
Designed for high-volume production of fine electronic wires, automotive harnesses, and specialty cables, the RLE-40H integrates electrical tubular annealing with a high-capacity molten tin bath (max. 300 kg) in one seamless pass. It replaces traditional batch annealing and separate tinning processes, significantly reducing labor, energy consumption, and material waste while ensuring consistent coating thickness and superior surface quality.
Advanced Design & Process Advantages
- Integrated Continuous Annealing + Hot-Dip Tinning: Wires first undergo precise electrical heating in a multi-zone tubular annealing furnace for uniform softening, then immediately enter a stable molten tin bath. Advanced wiping dies and dual-tank design (optional) guarantee smooth, adherent tin layers with minimal thickness variation (typically 1–5 μm).
- High-Speed Multi-Wire Capability: Simultaneous processing of 40 wires maximizes throughput for fine-gauge applications, achieving industry-leading productivity without compromising quality.
- Precise Temperature & Coating Control: Real-time electrical heating with PID control maintains optimal annealing and tin-bath temperatures (250–300 °C), preventing oxidation and ensuring bright, uniform tin coating with excellent solderability.
- Robust & Flexible Bobbin Handling: Compatible with pay-off bobbins 300–630 mm and take-up spools PT-4 to PT-15, supporting fast changeovers and high-volume runs.
- Energy-Efficient & Low-Maintenance Design: Electrical heating offers superior energy savings and easy temperature adjustment compared to gas-fired systems. Heavy-duty construction and proven RLB engineering ensure reliable 24/7 operation with minimal downtime.
- Compact Footprint: Space-saving layout ideal for modern cable plants seeking maximum output in limited floor area.
The result is defect-free, bright tin-plated copper wire that meets stringent IEC, RoHS, and automotive standards for electronics, telecommunications, and high-reliability wiring harnesses.
