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

Forming pass of the PU foam rolling shutter door roll forming machine: inside the enclosed roller stand, dark hardened rollers grip and shape the moving strip while a chain drive from the grey gearbox synchronizes the shafts above. The flat dark strip entering the circular guide and the finished black ribbed profile in the foreground show the slat skin taking shape.

Entry section of the PU foam rolling shutter door roll forming machine: two heavy polished chrome guide rollers align the flat dark steel strip as it feeds through the off-white bed, with thin chrome guide rods and a bright yellow safety panel behind. Correct entry alignment here keeps the double-skin slat profile square for a uniform polyurethane foam core.

PU foam metering station of the PU foam rolling shutter door roll forming machine: two large blue chemical tanks and a smaller pressure tank with gauge feed white pneumatic hoses toward the injection point, while an orange control box with green, red, yellow and white buttons and an ISO label on the tank manage the dosing. Drive shaft and double-row chain sprockets to the forming stations are visible below.

Close-up of the foam injection head on the PU foam rolling shutter door roll forming machine: two translucent feed tubes run through brass fittings and two green-handled valves into the black mixing block, whose downward nozzle injects polyurethane into the circular opening of the slat profile. This mixing head is the core of the insulation process that fills the double-skin cavity.

Full-length view of the PU foam rolling shutter door roll forming machine: rows of polished silver roller pairs sit in off-white stands under hinged yellow protective covers, with the main grey motor and electrical cabinet at the entry end. Test door-frame and track sections on the floor show the companion profiles this line can also produce alongside insulated slats.

Cutting station of the PU foam rolling shutter door roll forming machine: the orange blade guard and black saw block sit above a continuous dark-brown shutter slat profile with rounded interlocking hooks, and the white metal swarf on the bed shows the flying saw cutting to length during production. OMRON length control keeps every insulated slat within tolerance before the foam stage.

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

XINNUO has manufactured cold roll forming equipment since 1995 and builds the PU foam rolling shutter door roll forming machine as a complete insulated slat system rather than a single forming unit. Our own campus handles the whole chain in house - machining, mold processing, assembly, appearance processing and warehousing - so roller dies, frames and foam equipment are produced and matched under one roof.

The line combines double-skin roll forming, a two-component polyurethane metering and injection system with mixing block, a curing tunnel and flying saw cutting with OMRON encoder length control. Slat profiles from 75mm to 464mm are supported, together with door frame, edge frame, guide track, bottom beam and T-hook machines, so a buyer can equip an entire shutter workshop from one supplier.

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

FAQ

Q1: How does the PU foam rolling shutter door roll forming machine make an insulated slat?

A: Steel strip is roll formed into the double-skin slat profile, the slat then passes the polyurethane injection head where the two-component foam is dosed into the cavity, and after the curing tunnel the flying saw cuts the finished insulated slat to length.

Q2: What chemicals does the foam system use?

A: A two-component polyurethane system - polyol and isocyanate - held in separate tanks with a metering unit and pressure tank, mixed in the mixing block and injected through the nozzle into the slat cavity.

Q3: What slat sizes and profiles can be produced?

A: Insulated slats from 75mm to 464mm, covering common 84mm, 95mm, 110mm, 127mm and 140mm shutters plus wide industrial door slats. Roller sets are engineered to your drawing, and additional profile sets can be ordered later.

Q4: What output can the machine achieve?

A: Output depends on slat width, PU core thickness and the number of forming stations you choose, so we size the line to your daily target - tell us your required meters per shift and we will propose the matching configuration.

Q5: How good is the insulation performance?

A: The closed-cell PU core bonded between two steel skins gives the slat its thermal insulation and structural rigidity. Final performance depends on core thickness and foam density, which we select with you according to your climate and cold storage requirements.

Q6: What is included in delivery and installation?

A: The line ships as container-packed modules with hydraulic and control units pre-assembled. Our engineers provide on-site or guided installation and commissioning, plus operator training on forming, foam dosing and cutting settings.

Q7: How do you support buyers after shipment?

A: Remote technical support, spare parts supply and engineer dispatch are available for the service life of the machine. Central lubrication and standard components keep routine maintenance simple for your team.

Q8: How can I get a quotation quickly?

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