C: Duct Manufacture Auto-line Ⅲ

Line Ⅲ 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.

The work flow:
