I. Definition and Purpose
- Definition: A specialized equipment that uses roll-forming technology to bond metal coils (e.g., color steel, aluminum) with core materials (e.g., polyurethane foam, rock wool, fiberglass) into a three-layer composite structure ("metal surface + core + metal base").
- Purpose: Widely used for roofs and walls in industrial plants, warehouses, stadiums, cold storage facilities, etc., combining structural strength with thermal insulation.
II. Key Components
1. Uncoiling System
- Unwinds metal coils (top and bottom layers) with alignment correction devices.
2. Roll-Forming System
- Multiple sets of rollers shape metal sheets into profiles (e.g., corrugated, trapezoidal).
3. **Core Material Feeding System
- Automatically injects foam (e.g., polyurethane) or places pre-made insulation boards (e.g., rock wool).
4. **Lamination & Heating System**
- Bonds layers via heat pressing or adhesives to ensure structural integrity.
5. Cutting System
- Cures panels to preset lengths using hydraulic shearing or flying saws.
6. Stacking & Packing System**
- Automatically stacks and packages finished panels for transport.
III. Workflow
1. Loading: Metal coils and core materials are fed into the machine.
2. Forming: Metal layers are shaped, while the core is injected or laid.
3. Bonding: Layers are fused under heat/pressure or with adhesives.
4. Cooling & Solidification: Core materials (e.g., foam) are cured.
5. Cutting & Stacking: Panels are cut to length and stacked.
IV. Features & Advantages
1. High Automation
- PLC-controlled, minimal manual operation from uncoiling to stacking.
2. Versatility
- Produces panels of varying thickness (50-200 mm), width (600-1200 mm), and core materials.
3. Energy Efficiency
- Insulating cores reduce building energy consumption; some systems include waste heat recovery.
4. Precision
- Laser measurement and servo motors ensure accuracy (error within ±1 mm).
5. Durability
- Weather-resistant, corrosion-proof panels with a lifespan exceeding 20 years.
