Flexible Duct End Lining Machine | Inner Edge Liner Inserting Equipment

Factory Direct | 20+ Years Experience | Custom HVAC Solutions

Professional flexible duct end lining machine for applying inner plastic liner strips. Ensures smooth duct edges and easy HVAC duct connection. Factory direct supply.

Flexible Duct End Lining Machine

The Flexible Duct End Lining Machine is specially designed to apply a plastic liner strip inside both ends of aluminum flexible air ducts. This process creates a smooth and even duct edge, preventing exposed steel wire from affecting installation and ensuring easier, safer duct connections.

Unlike sealing or taping equipment, this machine focuses on inner edge finishing, making it an essential solution for high-quality flexible duct production.

Key Features

• Inner Liner Application Technology
  Precisely applies adhesive plastic strips to the inner edge of flexible ducts.
• Smooth Edge Finishing
  Eliminates exposed wire ends and ensures clean, professional duct openings.
• Improved Installation Efficiency
  Makes duct connection faster and easier for installers on site.
• Stable & Reliable Operation
  Heavy-duty structure with consistent performance for long-term production.
• Adjustable for Different Duct Sizes
  Suitable for various diameters of aluminum flexible ducts.

Applications

This machine is widely used in:

• HVAC flexible air duct manufacturing
• Aluminum flexible duct production lines
• Ventilation system factories
• Air conditioning duct processing

It is particularly suitable for manufacturers aiming to improve duct connection quality and installation convenience.

Why Inner Lining Matters

In standard flexible ducts, exposed steel wire at the ends can:

• Interfere with duct connections
• Damage sealing materials
• Reduce installation efficiency

By applying an inner plastic liner strip, the duct ends become:

• Smooth and safe
• Easy to connect
• More professional in appearance
