Duct Flexible Connector Line
■ Production Line to manufacture duct flexible connectors 
The automatic flexible duct connector production Line is consisted of de-coiler, hydraulic punching, roll former and notching, cutter  then the belt recoiling. If client has the large quantity production about the flexible duct connectors, this is the proper solution. The final products included punching anger and cutter all can be finished by one line.
The normal raw material of Flexible duct connector are the GI steel sheet and Fire-Resistant Fabric GC-PV (Polyester Vinyl), GC-SI(Silicone),GC-NE(Neoprene),GC-CV(Canvas). It can be installed between fans or similar equipment.

■ Technology Flow - Duct Flexible Connector Production Line
Duct flexible connector Roll Forming machine mainly consists of conic, guide equipment, leveling system, punching, roll forming system, cutting system, stacking equipment, hydraulic station, electrical control system.

■ Power Un-coiler (2sets)--- hydraulic holes punching -- Main Roll Former --- Notching & Cutter -- Re-coiler

■ Flexible Duct connector Application
The Flexible Duct Connector is designed to enable flexible joints of any size to be easily and economically formed in the
factory or on site. Flexible joints are installed between fans(or similar equipment) to prevent the transmission of vibration,
noise and rattles to the remainder of the air conditioning system.
