PU rolling shutter slat production line
has been designed to continuously produce roller shutter door slats with PU or polyurethane insulated; the door slats or window blinds hinge each other horizontally as roller shutter.A PU roller shutter slat production line
is ideal for the manufacturing rolling shutter slats with variable lengths and in large quantities. The alloy aluminum and galvanized zinc steel which is used to make slats have neat external appearance, even ripples, high utilization and strength. The PU or polyurethane foam insulated rolling shutter slats have good ability of heating preservation, compared to rolling shutter door slats
and roller shutter door panels
which have nothing thermal materials insulated.
There are two different transmission and roll forming systems optional for a PU rolling shutter slat production line: economical type (chain-brackets transmission and conjoint-stands roll forming system) and upgraded type (gear-box & universal joint shafts transmission and separate-stands roll forming stands).
A PU rolling shutter door slat production line
generally consists of a manual decoiler, a hydraulic punching tool is optional for some types of slats, a roll forming machine with heating system and transmission system, PU foaming machine with glue spray system, a tracking fly-saw cutter which cuts down over moving forward synchronously with the running of the line, a pneumatic stacker, and a PLC control cabinet.
