Line b consists of a feeding metal frame, leveler grooving roller, hydraulic notch and punch square machine, hydraulic shearer and folder. The electrical control system uses a computer with a closed-loop servo-system to increase the precision and reliability of the line. The maximum working speed is 10m/ min. The length tolerance is ± 0.5mm.The diagonal line tolerance is ± 0.8mm.
The capacity of the manufacturing process will produce 1000m2 of square duct.
