The main purpose of helical air pipe is to produce air vents, The main purpose of helical air pipe is to produce air vents, which meet all international standards: AFNOR, DIN, EUROVENT and SMACNA.
Duct line LMS-VI is our latest coil line. With U type structure, it cover less space and reduce time of plate passing which achieves the productivity of twenty-five seconds per piece.
Coil line LMS-II is mainly for TDF flange blanking, meanwhile, it can be used for normal sheet blanking. Matched with Pittsburgh lock former/ TDF folding machine and Angle joints, this duct line can produce very good TDF ducts.
Line III consists of a feeding metal frame, leveler grooving roller, hydraulic notch and punch square machine, Pittsburgh lock and single hem machine, servo motor and folder.
Line IV consists of a metal feeding frame, leveler and grooving roll. Hydraulic notch and punch square machine, hydraulic shear, movable Pittsburgh lock machine, duplex transverse flange manufacturing machine, and CNC system.
Line V consists of a metal feeding frame, leveler and grooving roll. Hydraulic notch and punch square machine, hydraulic shear, movable Pittsburgh lock machine, duplex transverse flange manufacturing machine, TDF hydraulic folder and CNC system.
