Fully Automatic PU Sandwich Panel Production Line
Description
This production line is a kind of specialized equipment for producing sandwich panel with the middle layer of anti-combustion polyurethane and with roof forming panel as the top face layer, aluminum foil as the bottom face layer. The sandwich panel is between 25 and 200mm in thickness, 1000mm in width, length determined by the customer. The sandwich panel is mainly used as keeping warm for wall and roof . Different insulating panels with other soft facing layers could also be produced on the line.
The operation principle of this line is as follows: raw materials of rigid-foam are delivered into the mixing head through the metering pump on the injection machine and then injected onto the bottom facing sheet going to conveyors along with the top superficial sheet. Between the upper and lower conveyors, the liquid materials are hardened into shape,after all for above actions are completed, by an automatic tracking cutting mechanism, cut into segments according to the preset length.

The type pursues board (basis on customer's requires to design)
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 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.
Advantages of Continuous Sandwich Panel Production Line
