Hot Gas Welding Machine for Cold Shrink Support Tubes is specialized equipment for producing spiral-welded support tubes used in cold shrink cable accessories. Key features include:

1. Working Principle:
   • Utilizes high-temperature gas (hot air) to melt the contact surfaces of plastic support strips, followed by pressure cooling to form uniform welds.
   • Temperature range: 180°C–280°C, with precise control via PLC modules for heat and speed.
2. Structural Design:
   • Hot Air System: Equipped with heating rods, guide tubes, and hollow welding heads to ensure consistent melt depth.
   • Drive Mechanism: Servo motor-driven winding shafts enable uniform feeding, compatible with tubes of various diameters.
3. Advantages:
   • Eliminates reliance on operator skill in traditional heat sealing, achieving high-strength welds without voids, critical for cold shrink tube applications.
   • Compatible with PVC, HDPE, polypropylene, and other thermoplastics, suitable for irregular or customized tubes.
