Automatic insulated flexible air duct making machine for HVAC systems. Combine inner duct, fiberglass insulation and outer jacket into finished duct with compression & packing. High efficiency, OEM solution.
The Insulated Flexible Air Duct Making Machine is a complete production solution designed for manufacturing glass wool insulated flexible ducts widely used in HVAC ventilation systems.
This production line integrates assembly, forming, compressing, and packaging, allowing manufacturers to produce high-quality insulated ducts with consistent structure and strong thermal performance.
It is especially suitable for HVAC duct factories, insulation material producers, and ventilation system manufacturers targeting Europe, Middle East, and North American markets.
✅ Full Production Process (Step-by-Step)
1. Manual Feeding & Layer Assembly
Three different materials are combined through a sleeve-type feeding system:
Inner Layer: Flexible duct with steel wire (aluminum foil or PVC duct)
Middle Layer: Fiberglass insulation (glass wool)
Outer Layer: Insulation jacket (aluminum foil outer duct)
Operator inserts materials into the forming sleeve to align all 3 layers.
2. Duct Pulling & Forming
The combined duct is continuously pulled out
Ensures tight wrapping and stable structure
Maintains uniform insulation thickness
3. Automatic Turning / Transfer
Finished duct is automatically flipped or guided
Moves smoothly into the compression section
Reduces manual handling
4. Insulated Duct Compressing
Duct is compressed to reduce volume up to 70%–80%
Makes transportation & storage highly efficient
Keeps duct structure intact after release
5. Automatic Packing
Compressed duct is:
Automatically pushed into carton box OR
Inserted into plastic bag
Ready for shipping immediately
