This short presentation tells the story behind the design and its intended use cases. Watch as we demonstrate the WNRLN USW-1500A ultrasonic spiral winding machine in action, showing how it automatically transforms PE strip coils into seamless plastic tubes through advanced ultrasonic welding technology. You'll see the PLC-controlled operation, adjustable winding speeds, and quick-change mandrel system that enables production of drainage pipes, ventilation ducts, and cable conduits from 50mm to 200mm diameter. Learn how this energy-efficient solution creates strong, environmentally friendly welds without adhesives or external heat.
