Hollow metal door frame roll forming machine brief.
The hollow metal door frame roll forming machine is a complete production line for the manufacturing of hollow metal door frame profile on the steel building construction.
The hollow metal door frame roll forming machine is a cost effective, flexible production line. It adopts many inline value added equipment to save the cost on secondary operation such like punching , notching , welding and polishing.
The standard profile drawing for hollow metal door frame
The roll forming process of metal door jamb roll forming line:
The metal door jamb roll forming line is starts from the unwinding of metal coils , entry the punching device after leveling , punched all the assemble holes and notched the angle corner,then roll formed to specific sections according to client’s design , cut to length by hydraulic cutting device then stack& packing.At last the whole door frame can be bend over and joint together by hands.
Decoiling—guiding&leveling —hydraulic punching—roll forming—-hydraulic cutting—-stacking—-bending(by hands)
