Gearbox Driven PU Foam Shutter Door Panel Roll Forming Line With Heating
These introductions refer only to the production line and configuration shown in the main image. Each machine is custom-built. Metalign welcomes your inquiry and provides the right production line—forming metal into profiles aligned to your needs.
1. Production Line Overview
This line is designed for clients in the building material, garage door, and industrial insulation industries. It offers precision shaping, continuous foam filling, and closed-section forming ideal for high-value insulated shutter slats.
2. Profile Description
This profile is a closed-section roller shutter slat formed from two galvanized steel strips (thickness 0.3–0.5mm), internally filled with polyurethane foam. It provides thermal insulation, noise reduction, and high strength, ideal for modern industrial or commercial roller doors.
3. Production Process
Manual Decoiler → Roll Former 1 → Guide Device → Roll Former 2 → PU Foam Injection Unit (A+B tanks) → Roll Former 3 → Straightener → Hydraulic Cutter → Out Table
The dual-strip roll forming line first pre-forms two steel strips separately, then guides and joins them before polyurethane foam is injected into the closed profile. A heated roll forming section ensures foam expansion and profile bonding. Final straightening and cutting ensure a clean finish.
4. Technical Parameters
| Machine | Analysis |
| Manual Decoiler (x2) | Holds top and bottom steel coils separately |
| Required for closed-type dual-strip design | |
| Roll Former 1 | Forms the inner section of the upper slat strip |
| 8 stations ensure pre-forming precision | |
| Guide Device | Aligns upper and lower strip before joining |
| Roll Former 2 | Forms lower strip while ensuring enclosure compatibility |
| Ensures closed structure before foam injection | |
| PU Foam Injector | Dual tank (A+B) system injects foam evenly |
| Critical for sound and thermal insulation | |
| Roll Former 3 | 14 stations complete profile and compress foam inside |
| Heating element boosts PU chemical reaction | |
| Straightener | Ensures final profile flatness and dimensional accuracy |
| Hydraulic Cutter | Saw blade cutting avoids profile deformation |
| Best for foam-filled closed shapes |
