Garage Door Roll Forming Line
Continuous PU sandwich panel line for insulated garage door
This garage door roll forming line is a continuous PU sandwich panel line that produces double-skinned sectional door panels with polyurethane insulated core. This garage door production line mainly consists of uncoiler, leveler, upper and lower roll formers, PU foam injection machine, hydraulic press, fly saw cutting system.
Samples of Finished Product
In the sandwich panel production process, PU foam is continuously sprayed under high pressure into upper and lower sheet metal profiles that are formed by upper and lower roll forming machines respectively. The PU insulated sandwich panel is then cut off to desired length via fly cutting saw prior to being discharged and collected.
