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 Production Process

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.

Features Quick change system of roll forming machine enables forming rolls to be quickly and easily changed for producing different profiles. PLC control system adopts imported motion controller to guarantee high precision, and drive system utilizes only Siemens servo motors. The roll forming line is designed with gear transmission system, ensuring that the machine has high precision and long lifespan. Fly saw cutting system adopts hydraulic cutting method.
