Roller Shutter Door Roll Forming Machine - Forming and Foaming Line for PU Insulated Slats

Cutting end of the roller shutter door roll forming machine: the saw mechanism sits above the heavy base with metal swarf scattered around it, while a yellow-grey drag chain carries cables along the frame and the ribbed run-out table receives cut lengths. A finished brown slat with clearly readable interlocking edges lies on the bed.

PU foaming section of the roller shutter door roll forming machine: two blue chemical tanks - the larger with an agitator motor on top and an ISO label, the smaller a pressurised tank with gauges - feed white hoses to the mixing head, while the two yellow enclosures behind are the heated curing chambers where the foam expands inside the slat.

Tight close-up of the injection manifold on the roller shutter door roll forming machine: the black mixing block with an eye bolt on top is held over the injection point by an L-shaped bracket, and two clear hoses enter through brass valves with green handles. A cream gearbox with double chain drive and a blue pressure tank sit blurred behind.

 Forming stations of the roller shutter door roll forming machine: pairs of polished chrome rollers in heavy off-white cast stands draw a dark pre-painted strip through and shape the slat profile step by step, with a hand-written number 2 marking one shaft and red protective caps on the drive ends behind. The strip is caught mid-forming.

Drive side of the roller shutter door roll forming machine: polished rollers shape the dark slat in off-white cast frames, each station driven by its own cream gearbox linked along a central chain-and-sprocket line, with the large grey motor and gearbox unit at the far right. The control panel with digital screen and red emergency stop is just visible.

Roller Shutter Door Roll Forming Machine - Manufactured by XINNUO Since 1995

XINNUO has manufactured cold roll forming equipment since 1995, and the roller shutter door roll forming machine is delivered as an integrated forming and foaming line. Chrome-plated forming rollers with per-station gearboxes shape the double-skin slat, the two-component PU system doses foam through the mixing head from an ISO tank and pressurised tank, and heated curing enclosures expand and set the core before the saw cuts to length.

The factory covers machining, mold processing, assembly, appearance processing and warehousing on its own campus and runs a dedicated mold processing hall, so roller dies, frames and foaming stations are produced and matched under one roof. Insulated slats from 75mm to 464mm are supported, with door frame, edge frame, guide track, bottom beam and T-hook machines available for a complete roller door workshop.

Finished insulated slats serve cold storage doors, freezer doors, insulated garage doors and industrial roller doors. We have exported to more than 150 countries with installation guidance, operator training and long-term spare parts support.

FAQ

Q1: What does a roller shutter door roll forming machine produce?

A: It turns steel coil into insulated roller door slats with interlocking edges, and can also produce the door frames, edge frames, guide tracks, bottom beams and T-hooks that complete a roller shutter door.

Q2: Why are the curing enclosures heated?

A: After the polyurethane is injected, the foam must expand and set. The heated enclosures keep the slat at a stable temperature through that reaction, so the core fills the cavity evenly and the slat keeps its straightness.

Q3: How is the two-component foam dosed?

A: The polyol and isocyanate components are held in separate tanks - a large tank with an agitator motor and a pressurised tank with gauges - and metered through clear hoses and brass valves into the mixing block, which injects the mixture at the profile opening.

Q4: What determines the quality of the finished slat?

A: Three things work together: chrome-plated rollers that form the skin without marking it, one gearbox per forming station linked by a central chain drive so every station runs synchronised, and correct foam dosing with a stable curing temperature.

Q5: Is the line easy for our operators to run?

A: Yes. The control panel with digital screen and emergency stop manages forming and cutting settings, a compact button panel sits at the foaming station for local operation, and we provide operator training covering forming adjustment, foam dosing and cutting lengths.

Q6: What slat sizes and steel thicknesses can be produced?

A: Insulated slats from 75mm to 464mm, covering common 84mm, 95mm, 110mm, 127mm and 140mm roller doors plus wide industrial profiles. Steel skin thickness and PU core thickness are selected to suit your door specification.

Q7: Can I inspect the machine before shipment?

A: Yes. We welcome factory visits, and for remote buyers we run the line on your profile and send test-run video, slat samples and inspection photos so you can approve the finished slat before the machine is packed.

Q8: How do I request a layout drawing and quotation?

A: Send your slat drawing or sample, steel thickness, PU core thickness and required daily output to WhatsApp/Wechat +86 188 0307 8605 or sara@xinnuomachine.com. Our engineer replies within 24 hours with a configuration plan, price and line layout.
