Duct manufacture auto line III The length tolerance is 0.5mm, diagonal tolerance is 0.8mm.
Line III consists of material feeding frame,leveler grooving rolls,hydraulic notching and punching square equipment and hydraulic folder.The electrical is controlled by computer.This control system has loop feedback system,with higher manufacturing precision and stability.The maximum work speed is ±16m/min,The length rolerance is ±0.5mm/m. The disgonal tolerance is ±0.8mm/m.It is highly efficiency and automatic and also save material.it is very sutiable for mass production of square duct.
Lin IIIcan not only be used for duct production but also for TDF(transverse duct snap flange system.)If HCHduct manafacture system combines a LTA-30(TDC flange machine),pittsburgh lock machine,folder and shaped clip,high quality ducts can be easily produced.
