The production line III mainly consists of electric decoiler, leveling & grooving device, hydraulic notching & punching device, hydraulic shearer and hydraulic folder. The precision and reliability of this Square Duct Production Line III is guaranteed by using a computer with a closed-loop servo-system in the electrical control system. Various production lines can be configured according to your detailed requirements.

• Two power metal feeding frames
• One leveling & grooving roller machine
• Four hydraulic notches and dies
• Hydraulic shearer and folding machine
• Industrial PLC control and specific software

This V type auto duct line is the basic machinery designed for any duct fabrication workshop. It can operate as a stand-alone unit for producing duct blanks or serve as the core module of a complete sheet-metal forming line.

It is capable of removing coil set, beading, and notching for both two-piece ducts and sprial ducts, and it performs cut-to-length shearing using a feed-to-stop process. There is no minimum cut length requirement and no restriction on minimum notch spacing.

The PC-based control system ensures consistent accuracy in feeding and length. Only one operator is required.

This duct production line consists of a coil-feeding frame, leveling and grooving rolls, a hydraulic notching and punching unit, a shear, a movable Pittsburgh lock-forming machine, a duplex transverse duct-flange forming machine, a TDF folder, and a CNC control system.
