Preda Machine provides the fastest, most reliable and cost saving auto duct line!
Available in operation in China and worldwide!.
The highest quality, most productive & cost efficient coil line (duct manufacturing) machines nowadays.
Use Japan MITSUBISHI PLC controller, servo motor drives that control the whole production line.
Accurate and accountable!
Our current main auto duct lines include auto duct line U 5, auto duct line 5, auto duct line 3,auto duct line 2.
Customized auto duct line acceptable!
U-type duct line 5structure requires smaller space, pretty much suitable for medium or small plant ductworks.
Pneumatic manipulators push plate in conjunction with combined lock forming machine, high speed and positioning more accurate.
Stepping out from traditional processing method, the lock former saves time greatly and significantly improve production efficiency.
Labor and time saver, high efficiency, a full piece of “口” shape duct can be finished in about 30 seconds
With production management functions: Day Count, Cumulative Count
Separate two kinds of input modes (touch screen and physical keyboard) ensure operation reliability greatly.
After inputting sizes you need on the screen of our duct line 5, production line can automatically do the decoiling, leveling, beading, notching, Pittsburgh locks, Duplex TDF flange forming, shearing, folding square.
Leveling roller isΦ70 solid roller, made by 45# strengthened and tempering steel coated with hard chrome to ensure long time using and leveling effect and protect the metal sheet from scratch.
Our duct line 5 is equipped with hydraulic shearing station with blade made by 6CrWu2Si steel, ensures the cutting accuracy ±0.5mm without burr on the duct sheared.
Auto duct line 3 performs almost the entire cycle of a rectangular duct (straight sections) - leveling, grooving, cutting corners under the flange, bending and cutting(except for Pittsburgh lock forming and TDF flange forming!).
After the auto line duct 3, Pittsburgh seam closer machine and TDF flange former must be fixed to the ends. With auto duct line 3 production process duct becomes more economical, faster and much more precise.
Production of large amounts of high-quality ducts can increase sales on the market in a short time, which makes those
manual shops would never compete with you!
Auto duct line 2 performs almost the entire cycle of a rectangular duct (straight sections) - leveling, grooving, cutting corners under the flange and cutting(except for Folding,Pittsburgh lock forming and TDF flange forming!).
The line consists of metal sheet cradle (usually its two or four decoilers to feed different thickness raw material for different duct diameters), feeding system with servo drive motor, beading rollers - to make stiffener ribs on the duct surface!
Shape and square notching and hydraulic cutting guillotine station.
The duct line 2 is automatically controlled by CNC PLC system with high-precision servo motors with feedback that allows you to achieve high accuracy, performance and reliability of the line.
The maximum operating speed of the line - 16m / min. Deviation ± 0.5 mm in length. Deviation ± 0.8 mm diagonal.
