Equipment shown here is used for continuously making sandwich panels with the facing layer (s) of color steel or galvanized sheet and the core material of polyurethane. Whole equipment is divided into PU insulation part and Facing sheet profiling part.
This line for roof and wall panel made of three kinds of material, in other words, sandwich panel including a Steel / Aluminium sheet + PU resin foam + Steel sheet, or Steel / Aluminium sheet + PU resin form + PVC Sheet
This line is easy to operate, high productivity, and reasonable price. Suitable for making roof wall color coated pu insulated sandwich panels and cool room insulated panels.
Whole line adopt PLC program control, with the communication module and inverter synchronization, highly automatically. Main machine adopt touch screen, simple operation. Productin line from uncoiler, roll forming, pu foaming, solidifying, automatically cutting, runout table ( opetional: auto stacker, auto packing ) to realize the auotmatically production process.
Whole line make up of Auto decoilers, roll forming machines, Flat pre-cutting devices, Transporting Conveyors, Steel plate pre-heating, Pressing machine, Tracking cutting, PLC control system, PU foaming machine, Hydraulic system and Pneumatic system etc.

Main Specifications

1. (a) Thickness : roof steel panel 30-200mm and wall steel panel 30-200mm.

(b) PU foam density : 40±5 kg/m³ ( or depend on requrement )

(d) Thickness of galvanizes color steel coil : 0.4mm~0.75mm

2. The production speed is different according to the panel thickness.

3. Speed of forming machine is 0~12m/min and adjustable. The length and amount of production can be set and count automatically by control panel.

4. Hydraulic material discharge stand can feed steel sheets automatically and keep accuracy during long time operation.

5. Bend saw cutter : Maximum thickness is 200mm. The suction channel is reserved for additional suction system to prevent the dust pollution.

6. The characteristic of this continuous rubber belt sandwich line is ALL parts including forming machine, lamination, conveyor, cutter and auto stacking equipment are synchronized by a central Ratio Setter control system. The user can easily control the speed through the main speed controller (VR).
