Copper Wire Tin Plating Machine

In the highly competitive wire and cable manufacturing industry, tin-plated copper wire remains the preferred choice for applications requiring superior solderability, outstanding corrosion protection, and consistent long-term electrical conductivity. As a trusted B2B supplier with over 20 years of expertise in cable production machinery, RLB introduces its High-Speed Electrolytic Copper Wire Tin Plating Machine — specifically engineered to apply uniform, high-quality pure tin coatings (99.9%) on soft annealed copper wire at line speeds reaching 16 m/s. This Copper Wire Electro Tinning Machine is the ideal solution for producers of automotive wiring harnesses, electronic components, transformers, communication cables, and specialty power distribution wires.

The RLB Tin Plating Machine combines precision current density control, intelligent tension management, and an advanced refrigeration cooling system to achieve coating thicknesses from 1–20 μm with minimal tin consumption per ton. The result is a dense, bright tin layer offering excellent adhesion that withstands subsequent drawing operations without cracking or peeling — fully compliant with ASTM B545 electrodeposited tin coating specifications for enhanced solderability and corrosion resistance in demanding environments.

Engineered Features Delivering Measurable Production Advantages

Our Copper Wire Tinning Machine is designed for maximum efficiency, reliability, and operator convenience:

• Controllable Power Supply & Precise Current Density Control: Delivers high plating efficiency, a compact tin crystal structure, and superior coating adhesion — critical for downstream processing and meeting automotive-grade IATF 16949 and ISO standards.
• Real-Time Thickness Monitoring System: Ensures uniform tin layers (±0.5 μm tolerance) across the entire wire length through continuous feedback and automatic adjustment.
• Energy-Efficient Refrigeration Cooling: Maintains optimal electrolyte temperature (typically 45–55°C) while reducing electricity consumption far below conventional water-cooling systems, lowering overall operating costs.
• High-Capacity Continuous Take-Up Innovation: Features an advanced wire storage and transfer system that supports 20% higher coil weights per coiler than standard models, enabling true non-stop production and significantly reduced downtime.
• Robust, Low-Maintenance Design: Average power consumption as low as 85 kWh/ton, stainless-steel 316L plating components for long-term durability, and 24/7 operational reliability with minimal maintenance requirements.

The outcome is a high-density, bright tin coating with exceptional solderability and oxidation resistance — precisely what modern automotive OEMs, electronics manufacturers, and EV battery cable producers demand.
