Application of Metal Faced PU Panels with Decorative Pattern Embossed
In recent years, there are many horizontally assembled PU panels increasingly popular in building industries, and the panels have PU insulated and metal faced embossed with decorative patterns.
PU sandwich panels are insulated panels that are commonly applied as roofing or wall of buildings for their thermal effects. Those PU sandwich panels are composed of two metal faces top and bottom layers, and Polyurethane materials insulated in the middle. The width of a PU wall sandwich panel is usually 1000mm, thickness of metal 0.3-0.6mm and they are assembled vertically as exterior wall panels. 
However, within the latest years, there are horizontal-assemblying type PU panels are applied in the makets, as the wall panels of watch boxes, residential houses, portable toilets, vending boxes and new stands etc.
These PU panels can be used as both exterior and interior wall panels. This kind of PU panels usually has one side metal, and the other size aluminum foil/film (sometimes both sides are metal), the width is 600mm maximum, thickness varies from 16mm to 50mm, and the surface of metal has been embossed or printed with some decoration patterns, like brick patterns, marble patterns, and wooden patterns etc.
The production line for make the Decorative patterns embossed, carved or printed metal PU wall panels consists of decoiler, metal embosser, roll forming machine, laminating machine, PU injection machine, fly-saw cutting unit, re-printing machine, drying unit and whole control system.
The metal embossing machine can be designed as per required patterns and materials. Two or three width adjustable roll forming machines are usually required for making exterior PU wall panels and interior PU wall panels. The lamination machine has been designed to be ajdustable for making PU insulated panels with different thickness. A fly-saw cutter has been applied to cut the final sheets with machine no stopping, and re-printing machine has the function to print the final sheets into different colours, like red, black or something else. The whole line is controled by PLC computer system, and after the required length, and quantities have been input via the touch screen, the whol line will start full-automatic production.

Frequently Asked Questions
What types of decorative patterns can be embossed on metal-faced PU panels? ›
The page shows that metal surfaces can be embossed or printed with patterns like brick, marble, and wood designs. The specific patterns available depend on the design of the metal embossing machine, which can be customized to match required patterns. Some surfaces may also be printed in colors such as red or black after the panels are cut.
What are the typical dimensions of decorative embossed metal PU panels? ›
According to the page, these horizontally assembled PU panels usually have a width of up to 600mm and a thickness ranging from 16mm to 50mm. The metal face is typically 0.3–0.6mm thick when made as exterior wall panels, though this may vary for interior panels or different applications.
What materials are used in the construction of these PU sandwich panels? ›
The panels consist of two outer layers—on one side metal (which can be embossed or printed) and the other side aluminum foil or film—with a polyurethane insulating core in between. In some cases, both faces may be metal. The metal surface is what carries the decorative pattern.
Can these panels be used for both exterior and interior applications? ›
Yes. The page states that these PU panels with decorative embossed faces can be used as both exterior and interior wall panels. They are commonly applied in structures such as residential houses, portable toilets, vending boxes, and newsstands.
How does the production line handle different panel thicknesses and widths? ›
The lamination machine is adjustable to accommodate different PU panel thicknesses. For width variation, two or three width-adjustable roll forming machines are typically used—one set for exterior panels and another for interior panels. The metal embossing machine can also be designed for the required pattern and materials.
How is the cutting and printing process managed during full-automatic production? ›
A fly-saw cutting unit cuts the panels to the required length without stopping the production line. A re-printing machine can apply colors like red or black to the final sheets. The whole line is controlled by a PLC computer system, where operators input the desired length and quantities via a touch screen for automatic operation.
What information is needed to configure a production line for these decorative panels? ›
To configure a line, you need to specify the decorative pattern (brick, wood, marble, etc.), the metal face material and thickness, overall panel width and thickness, whether both faces are metal or one is foil/film, and the desired production length and quantity controls. The metal embosser and roll formers can then be sized and tooled according to those requirements.
