Dual Coil PU Foam Insulated Shutter Slat Roll Forming Machine 15m/Min

Dual Coil PU Foam Insulated Shutter Slat Roll Forming Machine

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 → 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.

5. Key Focus

• Dual-strip design enables internal PU foam filling

• Gearbox-driven stations ensure high strength and forming precision

• Integrated heating enhances foam reaction and bonding

• Closed-shape design improves insulation and profile strength

• Clean saw cutting prevents foam deformation at the cut

• Ideal for insulated shutter slats with strict dimensional control
