PU Foam Rolling Shutter Door Roll Forming Machine - Polyurethane Slat Line

Wide view of the exit end of the PU foam rolling shutter door roll forming machine: the long line of forming stations ends at a flying circular saw with a bright orange guard that cuts profiles to length while running, with a large ribbed motor and two upright control consoles with PLC interface alongside. Cut slats leave here ready for polyurethane foam filling in the next stage.

Side view along the PU foam rolling shutter door roll forming machine: the off-white steel base carries a sequence of paired contoured rollers under bright yellow protective covers, and a dark steel strip can be seen being shaped in the foreground stations into the outer skin of the slat profile that will carry the polyurethane foam core. The linear arrangement of stands shows the progressive forming principle at work.

Macro view inside the PU foam rolling shutter door roll forming machine: a black lubrication manifold with brass fittings, one stamped 57-1, distributes lubricant through white push-to-connect hoses, while a circular metal collar and vertical rod support the mechanism above the dark profile passing through. Central lubrication keeps every roller shaft running smoothly through long production runs of insulated slats.

High-angle view over the forming stands of the PU foam rolling shutter door roll forming machine: each machined upright carries a vertical threaded adjuster with hexagon nuts for setting roller height and pressure, while polished guide bars keep the strip aligned and red universal joints link the roller shafts to the main drive. This station-by-station adjustment holds both slat skins consistent for a tight foam core.

 Precision close-up of the PU foam rolling shutter door roll forming machine: two heavy cast archway frames hold the roller shafts over the base plate, with a translucent yellow measuring wheel on an adjustable arm driving an OMRON rotary encoder that tracks material length and speed. Behind them, chain-and-sprocket drives from the gearboxes synchronize roller rotation as the pre-painted strip passes through.

PU Foam Rolling Shutter Door Roll Forming Machine - Built by XINNUO Since 1995

XINNUO has designed and built cold roll forming equipment since 1995, and our PU foam rolling shutter door roll forming machine range covers the complete insulated shutter system - not just the slat. More than twenty-eight production-proven profiles span PU foam filled double-skin slats from 75mm to 464mm, door frames and edge frames, guide tracks, bottom beams and T-hooks, so a single supplier can equip your whole shutter workshop.

A complete PU slat line combines roll forming, polyurethane foam injection, a curing tunnel and flying saw cutting. Forming sections use gear drive for quiet, high-accuracy shaping of narrow and medium slats, or chain drive for wide industrial profiles, and are built on square-tube, H-beam or heavy cast archway frames according to duty. Flying saw cutting with OMRON encoder length control, central lubrication manifolds and threaded roller adjusters keep the closed-cell PU core square and the slat surface clean.

Downstream, our insulated roller shutter slats serve cold storage doors, cold room and freezer doors, insulated garage doors and energy-saving industrial doors in markets across Europe, the Middle East, Africa and the Americas. We have exported to more than 150 countries, providing installation guidance, operator training and dependable after-sales support throughout the equipment's service life.

FAQ

Q1: What is a PU rolling shutter door roll forming machine? A: It is a roll forming line that produces insulated shutter slats - two steel skins with a polyurethane (PU) foam core injected and cured between them - and can be supplied together with door frame, guide track and bottom beam machines.

Q2: Why use PU foam instead of a plain hollow slat?

A: PU foam is the insulation material used in the vast majority of insulated roller shutters. It fills the cavity between the two skins, adding thermal insulation, reducing noise and increasing the structural rigidity of every slat.

Q3: How is the polyurethane foam injected?

A: After the double-skin slat profile is formed, the line feeds it to a foam injection station where PU is dosed into the cavity; the slat then passes through a curing tunnel so the foam sets before cutting.

Q4: What does a complete PU slat line include?

A: Roll forming with a high station count for the double-skin profile, a polyurethane foam injection system, a curing tunnel, a flying saw or shear for cutting to length, and a run-out table - arranged to your plant layout.

Q5: What slat widths can the machine produce?

A: PU slats from 75mm to 464mm are available, covering common 84mm, 95mm, 110mm, 127mm and 140mm insulated shutters plus wide industrial door slats.

Q6: Should I choose gear drive or chain drive?

A: Gear drive is the mainstream choice for slats up to about 140mm - quieter and more precise. Chain drive suits wide industrial slats and higher torque duty. Frame options include square tube, H-beam and cast archway construction.

Q7: Where are PU insulated slats used?

A: Mainly where thermal separation matters: cold storage doors, cold room and freezer doors, insulated garage doors, temperature-controlled warehouses and energy-saving industrial doors in cold-climate markets.

Q8: How do I get a quotation?

A: Send your slat drawing or sample, PU core thickness, steel thickness and daily output target via WhatsApp/Wechat +86 188 0307 8605 or email sara@xinnuomachine.com. We reply within 24 hours.
