Product Description
1. Overview Engineered for the transformer industry, this cold welding foil winding machine integrates innovative solid-state welding technology with high-precision automation. It handles copper and aluminum foils (width 600–1600mm) with consistent tension and edge alignment, ensuring superior coil quality for power distribution, renewable energy, and industrial machinery applications. The PLC-controlled system automates feeding, winding, cutting, and welding—reducing labor costs while boosting throughput. 2. Key Performance Parameters
3. Core Advantages ① Cold Welding Technology (Heat-Free) Eliminates thermal damage to foil insulation. Creates strong, low-resistance inter-layer joints without oxidation or scaling. Enhances transformer efficiency, reduces hot-spot risks, and ensures mechanical stability under short-circuit forces. ② Wide Winding Range (600–1600mm) Versatile platform accommodates diverse transformer sizes—from distribution to large power transformers. Flexible for multi-spec production without machine changeover. ③ Servo Tension & Edge Control Maintains uniform tension throughout the winding cycle. Prevents foil stretching or wrinkling. Combined with automatic edge guidance, ensures ±0.5mm alignment for consistent layer stacking. ④ PLC Programmable Automation Store unlimited winding recipes (speed, turns, pitch, tension curves). One-key recall for repeatable batch quality. Auto fault detection stops machine instantly on deviation—protecting product and equipment. ⑤ Labor Saving & Throughput Integrated auto feeding, precision cutting, and cold-weld execution reduce manual handling by up to 60%. One operator can manage multiple units. Cycle time significantly reduced vs. manual methods. ⑥ Durable Industrial Build Heavy-duty welded steel frame (green/orange finish), precision-machined spindles, sealed guides. Built for 10+ years of continuous operation with minimal maintenance. Low wear due to smooth servo motion. 4. Typical Applications
