Insulated Flexible Air Duct Making Machine | Glass Wool Flexible Duct Production

Product Specification

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
